Auto High-Beam (High-Beam Support System) Description - Overview
Overview
The system operates by switching the high beam and low beam automatically depending on the road condition of vehicles running
ahead and opposite vehicles, using the multipurpose camera unit.
Operating Conditions
The combination light switch is in the AUTO position.
The headlight low beam is turned on.
White and red light sources are not detected ahead.
2 or more streetlights have not been detected.
The vehicle speed is above 25 mph (40 km/h).
There is no halation state in front of the vehicle.
There is no manual operation input of the combination light switch.
NOTE: Weather and road conditions (undulation, curve, or environment illuminance etc.) may affect system operation.
Stopping Condition
When the dimmer switch is operated.
When the vehicle speed is low:
－ Less than 6 mph (10 km/h)
－ Less than 15 mph (24 km/h) condition continues more than four seconds.
Conditions that the System Switches to Low Beam
When there are objects that are emitting lights such as streetlights, house lights, advertising display lighting, signages, vending
machines, or other reflecting light.
When there are objects emitting lights on the road similar to the taillights of vehicles driving ahead or headlights of opposing
vehicles.
When the red lights of the traffic signals are detected.
When the front wiper motor operates at HIGH for 5 seconds.
Conditions that Switching Timing to Low Beam is Changed
When the taillights of the vehicle driving ahead are bright or dark.
When the headlights of the opposite vehicle are bright or dark.
In rainy, snowy, and foggy weather.
Detection Range and Limits
The multipurpose camera unit recognizes and reacts within the range of 25 degrees horizontally (total 50 degrees).
cardiagn.com
The system stops operation under the following conditions.
When the combination light switch is turned to other than the AUTO position.
When a system malfunction occurs, or when the camera lens or the windshield gets dirty, the warning message is shown on the multiinformation display (MID). If the warning message is shown, the system stops operating.
NOTE: The actual message may be different depending on your market.

Exterior Lights System Description - Components
Headlights
The vehicle uses LED headlights or halogen headlights. The headlight assembly consists of the headlights (Low/High beam), the front
parking/daytime running lights, and the front turn signal lights.
Rear Combination Lights
The taillights consist of the taillights, the inner taillights, the brake lights, the rear turn signal lights, the back-up lights, and the rear side
marker lights on the outside of the vehicle.
High Mount Brake Light
The high mount brake light is located on the rear shelf, top of the rear window, or the rear spoiler, and it is equipped with the bulb or
the LED.
Side Turn Signal Lights (With Mirror Turn Signal)
cardiagn.com
The side turn signal lights are built into the power mirror, and are equipped with the LED.
Exterior Lights System Description - Control/Function
Headlights Function
The headlights are controlled by the body control module, based on combination light switch input signals.
Headlights Auto-OFF Function
cardiagn.com
When the headlights auto-off function is selected, the exterior lights automatically turn off when the vehicle is in the OFF (LOCK)
mode, and the driver's door is opened and closed. The timing for turning off the exterior lights can be customized to suit the customer
needs.
Headlight Fault Detection Function (With LED Headlight)
When a low beam error is detected, the headlights send an error signal to the body control module. When the body control module
receives the error signal, it sends an LED headlight system indicator signal to the gauge control module via the B-CAN.
cardiagn.com
Turn Signal/Hazard Light Function
One-Push Turn Signal Light
With the vehicle in the ON mode, when there is a brief input from the turn signal switch, the body control module flashes the left or
right turn signal three times in succession.
Fog Light Function (With Fog Light)
The fog light is controlled by the body control module, based on the switch input from the combination light switch.
Daytime Running Lights Function
For daytime running light control, the body control module controls the daytime running light relay based on the combination light
switch signal, the parking brake signal, and the automatic lighting signal, and then turns on the light. When the combination light
switch is in the OFF position or the AUTO position at the time of the vehicle ON mode, and the parking brake is released, the body
control module controls the daytime running light relay. When the combination light switch is in the ON position or the AUTO position,
and the low beam output signal from the automatic lighting control unit-sensor or the automatic lighting/rain sensor are inputted to the
body control module, daytime running light control is not performed.
cardiagn.com
The turn signal/hazard warning lights are controlled by the body control module, using input from the combination light switch or
hazard warning switch signal. When the body control module receives a left turn or right turn command from the combination light
switch, it blinks the front and rear turn signal lights for the left or right side of the vehicle. When the body control module receives a
hazard warning command from the hazard warning switch, it blinks the front and rear turn signal lights for both sides of the vehicle.
The system also includes wire break detection by monitoring the current values using the body control module. An abnormal value is
registered as a wire break (open) or faulty bulb or LED. When this occurs, the body control module increases the turn signal lighting
frequency. If the break detection shows that the current value has returned to the correct value, the body control module returns to the
normal frequency.
When the light ON delay time elapses after the automatic lighting control unit-sensor or the automatic lighting/rain sensor output
voltage drops to the light ON luminance, the front parking lights, the side marker lights, the taillights, the license plate lights, and the
headlights turn on. When the light OFF delay time elapses after the automatic lighting control unit-sensor or automatic lighting/rain
sensor output voltage rises to the light OFF luminance, the front parking lights, the side marker lights, the taillights, the license plate
lights, and the headlights turn off.
Without Automatic Wiper
With Automatic Wiper
cardiagn.com
Automatic Lighting ON/OFF Control
cardiagn.com
Wiper Linked Mode
When the wiper switch is in a position other than OFF, the automatic lighting control unit-sensor*1 or automatic lighting/rain sensor*2
counts and records the windshield wiper motor ON to OFF signal (edge count) within 20 seconds from the body control module (FR
WIPER AS signal) via the B-CAN. After a total of 5 counts*1 or 4 counts*2, it switches to wiper linked mode and turns on the
headlights, the front parking lights, the taillights, inner taillights, and the side marker lights. The ON/OFF signals at the time of
windshield washer operation are not counted. When an edge count is not received for 30 seconds or more, the count is reduced by 1,
and shifting to normal mode is done when the count reaches 0. The wipers return to normal when the vehicle is stopped, or when the
respective switch is set to OFF.
*1: Without automatic wiper
*2: With automatic wiper
The automatic lighting control unit-sensor or the automatic lighting/rain sensor sends an indicator signal to the gauge control module
in case of failure of the automatic lighting sensor or when the signal sent from the body control module by B-CAN signal is abnormal.
Sensitivity Adjustment Function
Sensitivity adjustment function of the automatic lighting system can be customized with the gauge control module. You can select the
customized timing from 5 types (Min, Lo, Mid, Hi, Max) sensitivity.

How to Set Readiness Codes
Malfunction Indicator Lamp (MIL) Indication (In relation to Readiness
Codes)
The vehicle has certain readiness codes that are part of the on-board diagnostics for the
emissions systems. If the vehicle's 12 volt battery has been disconnected or gone dead, if DTCs
have been cleared, or if the PCM has been reset, these readiness codes are reset to incomplete.
In some states, part of the emissions testing is to make sure these codes are set to complete. If
all of them are not set to complete, the vehicle may fail the emission test, or the test cannot be
finished.
To check if the readiness codes are set to complete, turn the vehicle to the ON mode, but do not
start the engine. The MIL comes on for 15－20 seconds. If it then goes off, the readiness codes
are set to complete. If it flashes five times, one or more readiness codes are not set to complete.
To set readiness codes from incomplete to complete, do the procedure for the appropriate code.
To check the status of a specific DTC system, check the OBD status in the DTC MENU with the
HDS. This screen displays the DTC, the current data list of the enable criteria, and the status of
the readiness testing.
NOTE:
During the procedure, do not turn the vehicle to the ACCESSORY mode or the OFF (LOCK)
mode.
All readiness codes are cleared when the 12 volt battery is disconnected, if DTCs have been
cleared, or if the PCM is reset with the HDS.
Low ambient temperatures or excessive stop-and-go traffic may increase the drive time
needed to switch the readiness code from incomplete to complete.
The readiness code will not switch to complete until all the enable criteria are met.
If a fault in the secondary HO2S system caused the MIL to come on, the readiness code
cannot be set to complete until you correct the fault.
Enable Criteria
ECT SENSOR 1 at 158 °F (70 °C) or more.
IAT SENSOR at 20 °F (-7 °C) or more.
Vehicle speed above 25 mph (40 km/h).
Procedure
1. Connect the HDS to the vehicle's data link connector (DLC), and bring up the READINESS
CODEs screen for Catalyst in the DTCs MENU.
2. Start the engine.
3. Test-drive the vehicle under stop-and-go conditions with short periods of steady cruise. After
about 5 miles (8 km), the readiness code should switch to complete.
4. If the readiness code is still not set to complete, check for a Pending DTC with the HDS. If
there is no DTC, one or more of the enable criteria were probably not met; repeat the
procedure.
Evaporative Emission (EVAP) Control System Monitor and Readiness
Code
NOTE: All readiness codes are cleared when the 12 volt battery is disconnected, if DTCs have
been cleared, or if the PCM is reset with the HDS.
Enable Criteria and Procedure

Procedure
1. Start the engine.
3. Check the readiness codes screen for the AIR FUEL RATIO (A/F) SENSOR in the DTCs
MENU with the HDS.
If the HDS indicates complete, readiness is complete.
If the HDS indicates not complete, go to the next step.
4. Check for a Pending DTC. If there is no DTC, the enable criteria was probably not met. Select
the DATA LIST Menu. Check ECT SENSOR 1 in the ALL DATA LIST with the HDS. If ECT
SENSOR 1 is less than 140 °F (60 °C), run the engine until it is more than 140 °F (60 °C),
then repeat the procedure.
Air Fuel Ratio (A/F) Sensor Heater Monitor Readiness Code
NOTE: All readiness codes are cleared when the 12 volt battery is disconnected, if DTCs have
been cleared, or if the PCM is reset with the HDS.
Procedure
1. Start the engine, and let it idle for 1 minute. The readiness code should switch from
incomplete to complete.
2. If the readiness code is still not set to complete, check for a Pending DTC. If there is no DTC,
repeat the procedure.
Misfire Monitor and Readiness Code
This readiness code is always set to available because misfiring is continuously monitored.
Monitoring pauses, and the misfire counter resets, if the vehicle is driven over a rough road.
Monitoring also pauses, and the misfire counter holds at its current value, if the throttle
position changes more than a predetermined value, or if driving conditions fall outside the
range of any related enable criteria.
Fuel System Monitor and Readiness Code
This readiness code is always set to available because the fuel system is continuously
monitored during closed loop operation.
Monitoring pauses when the catalytic converter, the EVAP control system, and the A/F
sensor monitors are active.
Monitoring also pauses when any related enable criteria are not being met. Monitoring
resumes when the enable criteria is again being met.

How to Troubleshoot the Auto High-Beam (High-Beam Support System)
Auto High-Beam Indicator (Green)
When the Auto High-Beam is OK, the Auto High-Beam indicates its operation on the gauge
control module as below.
NOTE:
For Auto High-Beam function, review the Auto High-Beam Description.
Self-Diagnostic Function
The Auto High-Beam has a self-diagnostic function. If a malfunction of the Auto High-Beam
detects a problem while in operation, a warning message is displayed on the multi-information
display (MID), the Auto High-Beam stops operating, and stores DTCs.
NOTE: The Auto High-Beam operates while maintaining a mutual connection between the
multipurpose camera unit at the control origin and the other control units (relay control module,
MICU, gauge control module, automatic lighting/rain sensor, etc.). If malfunctions occur in these
control unit systems, the Auto High-Beam does not operate. At this time, warning indicator of the
related control unit turn on and a warning message is displayed on the multi-information display
(MID).
Dirt or dust detective function (CLEAN FRONT WINDSHIELD Indication)
If the message Some Driver Assist System Cannot Operate: Clean Front Windshield appears on
the MID, the camera lens or the windshield has enough dirt so that the camera view is obstructed.
The Auto High-Beam stops operating.
cardiagn.com
The Auto High-Beam communication with other control units via the F-CAN. For Auto
High-Beam diagram, review the Auto High-Beam Diagram. If a connected unit malfunctions,
the Auto High-Beam will not operate. In this case, both Auto High-Beam indicator and
connected unit indicator come on and stay on (except for the gauge control module).
Clean any dirt or contamination on the camera lens or the windshield. Once the camera's view is
unobstructed, the MID turns off and the Auto High-Beam automatically turns back to ON.
Multipurpose Camera unit
The Auto High-Beam of this vehicle is controlled by the multipurpose camera unit. If an error or
malfunction of the multipurpose camera unit occurs, the Auto High-Beam does not operate. At
this time, a warning message is displayed on the multi-information display (MID). The operations
of the Auto High-Beam corresponding to the multipurpose camera unit malfunctions can be
checked in the troubleshooting list by each DTC for the multipurpose camera unit.
If the message Some Driver Assist Systems Cannot Operate: Camera Temperature Too High
appears on the MID, the Auto High-Beam stops operating, and stores a DTC.
When the multipurpose camera temperature cools down to its proper operating temperature, the
indicator on the MID turns off, and the Auto High-Beam automatically resumes operation.
Multipurpose Camera Aiming Function
If the multipurpose camera unit is removed or replaced, you must do the multipurpose camera
aiming procedure. If the aiming is incomplete, the Auto High-Beam indicator blinks.
CAN communication
The Auto High-Beam communicates with other control units via the F-CAN. For Auto High-Beam
diagram, review the Auto High-Beam Diagram.
If the multipurpose camera unit detects a communication error or a malfunction in another
connected unit, the Auto High-Beam will not operate even though it is OK. In this case, both the
Auto High-Beam indicator and the related unit indicator will come on and stay on.
Intermittent Failures
The term ''intermittent failure'' means a system may have had a failure, but it checks OK now. If
you cannot reproduce the condition, check for intermittent failure DTCs. If intermittent failure
DTCs are not stored, check for loose connections and terminals. Also check ground and power
connections related to the circuit that you are troubleshooting.
How to Troubleshoot DTCs
Check the DTCs with the HDS.
NOTE: For Auto High-Beam DTCs, refer to the DTC troubleshooting index.
Before troubleshooting, check and note these items:
cardiagn.com
System Protect Function (High temperature) (MULTIPURPOSE CAMERA
HOT Indication)
Ask the customer about the conditions when the problem occurred, and try to reproduce the
same conditions for troubleshooting.
If the symptom does not appear and the Auto High-Beam indicator does not come on while
test-driving, but your troubleshooting was based on the DTC, check for poor connections or
loose terminals at all connectors related to the circuit that you are troubleshooting.
After the troubleshooting or repairs are done, clear the DTCs, and test-drive the vehicle
under the same conditions as when the DTC was originally set. Make sure the Auto
High-Beam warning message does not come on.
The Auto High-Beam sometimes stops operating because of the environment (weather, road
conditions, driving conditions, etc.). A intermittent failure DTCs.
How to Retrieve DTCs
NOTE:
