Issue 01
The CAN bus that connects to the CAN interface for the installer is called the external CAN bus below.
The CAN protocol contains all messages sent and received by the engine control unit.
REQUIREMENT!
Two messages received by the engine control unit take high priority:
•
DLN1 proprietary
•
Cruise Control/Vehicle Speed
If these two messages are not received, fault codes will be created.
The CAN protocol used is based on SAE J1939-71.
•
A summary of the available CAN messages in the external CAN bus is contained under the heading Summary of CAN messages. This also lists
the engines for which the various messages are applicable.
•
Detailed information about each individual CAN message is contained under the heading Detailed description of CAN messages.
Introduction
Introduction
•
The communication speed is 250 kbit/s.
•
Control units connected to a CAN bus must be able to handle up to 100% bus load with the correct messages with no significant functional
limitations or malfunctions.
•
As a rule of thumb bus load should not exceed 80%.

Summary of CAN messages
CAN message sent from engine
The following tables use the concepts below:
For the content of messages with PGNs specified in SAE J1939
•
Not defined: Not defined in SAE J1939.
•
Not used: Defined in SAE 1939 but not used by Scania.
IMPORTANT!
For Not defined and Not used, FF must be sent or received.
The CAN specification applies to both engine control units S6 and S8. The lists contain two columns with the headings EMS S6 and EMS S8, the
message only applies to the engine control unit marked with a cross. The engine control unit which the message does not apply to should be
considered Not Used.

A: Specifies which version of the DLN1 message this is. If the version is incorrect, a fault code is created and the engine control unit will use the
basic value for the contents of the message. For SW-Basic 1 721 428 both 0xA0 and 0xA1 versions are permitted.
B: Values between 0xFB and 0xFD are not permitted.

A: If the incorrect version is specified, a fault code is generated and the engine control unit will use the basic values for the contents of the message.
B: If Torque enable is engine speed control, see note D. Increase or decrease the reference speed (with or without droop, see note. C) in relation to
nominal engine speed. The setting range can be changed with calibration parameters, normally ±120 rpm.
Example:
Nominal engine speed at full load
1,500 rpm
Droop
4%
Minimum offset
-120 rpm
Maximum offset
+120 rpm
Nominal speed offset
0x3A = 58% gives an engine speed offset of +19.2 rpm
Reference speed to control unit at full load 1,500 / 19.2 / 1,519.2 rpm
Reference speed to control unit without load 1,500 + 0.004*1,500 + 19.2 = 1579.2 rpm
If Torque enable is Torque control, see note D. The torque request according to the maximum available torque at current engine speed.
C: Engage or disengage the droop function. The droop value can be changed with a calibration parameter or with TSC-proprietary.
D:
00 Means engine speed control with Nominal speed offset. Som beskrivet i not B.
01 Means torque control with Requested Torque. As described in note B.
E: The start request for the starter motor is connected and controlled by the engine control unit.
Detailed description of CAN messages sent to engine
Note: The DLN1 message for checking a single speed engine can be run together with or be de-prioritised by the message TSC-proprietary.

A: The request to start sending fault codes and delete saved fault codes.
If the switch is pressed down for more than 0.2 s and then released, the engine control unit starts sending fault codes in the DLN2-Proprietary
message.
If the switch is pressed down for between 2.5 to 10 s at system start (ignition on), saved fault codes are deleted. The fault codes which can only be
read with SDP3 are not deleted.
B: This switch can be used to stop the engine from switching off due to low oil pressure, low coolant level or high coolant temperature.

A: Only Speed Control or Speed Limit is permitted.
B: If status 10 is received, a more powerful regulator is used, otherwise a normal regulator is used.
C: If medium or low priority is received, the request from TSC1 can be de-prioritised by Accelerator Pedal in the DLN1 message. If highest or high
priority is received, the normal accelerator pedal has no affect. This applies only to Speed Control. For Speed Limit the accelerator pedal can never
exceed the limit.

The TSC-proprietary message can be co-run with the DLN1 message to control single speed engines.
The TSC-proprietary message has higher priority than the DLN1 message. If the message is not received by the engine control unit or if the values
are Not available, Error or Out of range, congruent values in the DLN1 message will be used. Alternatively, EMS parameters will be used.

The droop value is defined as: (n2 - n1)/Nominal rpm * 100 (%).
B: It is possible to control torque instead of engine speed. The torque level is related to the maximum available torque.
The values between -125% and 0% are seen as 0%, and the values between 100% and 125% are seen as 100%.
Detailed description of CAN messages sent to engine
A: The nominal engine speed is the engine speed at a defined load (stored in the engine control unit, normally 100% and only valid when the droop
level is >0%). The requested engine speed depends on the current load, speed offset and droop.
D: It is possible to select whether the usual offset signal (message DLN1, Nominal speed offset) is to be used or not.
•
If Override Control Mode Priority is the same as Highest- or High Priority, DLN1 Nominal speed offset will be ignored.
•
If Override Control Mode Priorityis the same as Medium- or Low Priority, DLN1 Nominal speed offset will be used.
E: It is possible to adjust the droop value which is stored in the engine control unit. The current droop value is sent with DLN2, Single Speed Droop.
F: It is possible to request the desired droop value directly.

C: It is possible to select hardness on the engine speed regulator.

DTC = Diagnostic Trouble Code (fault code)
A: Normally controls the high coolant temperature warning lamp. The message is sent when the coolant temperature exceeds the limit (normally
95°C).
B: The message is sent if the function for reducing engine output due to high engine temperature is selected and the engine temperature exceeds the
upper limit (normally 95°C).
C: The message is sent when the coolant temperature exceeds the switch-off limit (normally 103°C).
D: For low urea level, use message DLN8 instead.
E: For engines with 2 generators, the message Generator not charging is sent so that none of the generators charges.

•
As soon as at least one DTC is activated, the lamp becomes Active. If all DTCs become inactive, the lamp is Not activated.
•
The engine control unit is started with the signal U15 - ON. During the first few seconds that U15 is activated, the lamp is Activated.
•
When the engine control unit is switched off with the signal U15 - OFF, the lamp will be Activated until the engine speed is 0 r/min and all
engine data is stored in the memory. After that the system shuts down and no more messages are sent. All fault codes are saved in two memories,
the flash code memory and the DTC memory in the engine control unit.
•
The DTCs can be read with the KW2000 command and the flash codes can be sent in this message together with a request in the message
Cruise Control/Vehicle Speed - K Engine Test mode switch.
G: When the diagnostics switch (in the message CruiseControl/VehicleSpeed-K - Engine Test mode switch) is activated, status 10 is transferred.
While the flash codes are being transferred, status 01 is transferred.
H: When a new DTC has been saved in the engine control unit, status 01 is sent for 1 second.
I: For single speed engines, the current droop value is sent. For all speed engines, the value FF - Not available is sent.
