Connect the Red test lead from the scanner to the power supply socket (B+) on the Diagnostic Connector, where available, or to the vehicle's battery via the extension cable and battery clamp supplied.

Connect the Black test lead from the scanner to the ground socket on the Diagnostic Connector. Now the scanner powered up and the power indicator light should be fully illuminated. The screen will display E 1.

Note:

Power indicator light (LED) must light up. If it does not, refer to the list below for detailed test.

Refer to the connection table of this manual; check the Red and Black test lead with the socket number on the

Diagnostic Connector, Is there an incorrect or weak connection?

Check the power requirement on the Diagnostic Connector. (Must be performed with the ignition ON when connected with 16-pole diagnostic connector at socket 16)

Connect the Yellow test lead to the system diagnostic socket that you use to extract codes.

Refer to this manual or Mercedes Benz maintenance manual for location of the Diagnostic sockets for the type of Diagnostic Connector fitted to the vehicle and the system capabilities available for code access on the applicable Diagnostic sockets.

5. Identification/Rectification of Faults

A.

Identify fault code and related circuit using this manual or using the factory diagnostic manuals available from Baum Tools Technical Publications 415-566-9229.

B.

Carry out required repair before clearing fault codes.

About Current, Stored and Registered Faults

Current Faults - These faults are detected while the car is running at idle or speed. They represent components currently failing. These codes cannot be erased, and are only meaningful with the ignition on and the engine running. Codes found in this system with the KOEO have no meaning. Components not present on the vehicle may be flagged as failing by the cars internal diagnostics due to the generic nature of the cars software. This is particularly true in C-Class (202) cars.

Stored or Permanent Faults - These faults are recorded in the permanent memory of the cars system controller and are the main cause of MIL illumination. These codes can be erased.

Registered Faults - These faults are recorded in the temporary memory of the of the cars system controller. This temporary memory records the number of times a component fails. When a certain number of failures has occurred the fault is moved to permanent storage and the Check Engine Light (MIL) will be illuminated. On cars equipped with Fault Registers the Check Engine Light may stay on after the Stored or Permanent Fault has been erased if another occurrence of the fault has happened since the Permanent Fault was stored. To extinguish the light erase the Stored and Registered faults. These codes can be erased.

16



Check Engine Light Diagnosis

Mercedes S(140), SL(129), E(210) and C(202) class have multiple systems which can turn on an Check Engine

Light. All related systems must be tested for codes and repaired before the light will extinguish.

OB15-12 Memory Cartridge - Mercedes Benz Analog & Digital Fault Codes

1. Setting Up

ATTENTION: DO NOT INSERT CARTRIDGE WITH POWER SUPPLIED TO THE CS1000.

PROPER USE OF THE MERCEDES DIAGNOSTIC SYSTEM

Identify vehicle Model and Month/Year of production

Confirm specific drivability complaint. If MIL is on, when did it come on and under what conditions?

Insert the OB15-12 memory cartridge into the base of the scanner. Make sure the arrow on the cartridge is facing up as it is inserted. Gently push the cartridge into the CS1000 until the cartridge seats completely.

Refer to Diagnostic Cable introduction page 9 and connection table page 10 of this manual to determine vehicle cable requirements. Connect the cable specified to the scanner and to the vehicle Diagnostic

Connector.

Connect the 25-pin cable connector head firmly to the scanner 25-pin connection port.

Connect the Red test lead from the scanner to the power supply socket (B+) on the Diagnostic Connector, where available, or to the vehicle's battery via the extension cable and battery clamp supplied.

Connect the Black test lead from the scanner to the ground socket on the Diagnostic Connector. Now the scanner powered up and the power indicator light should be fully illuminated. The screen will display 1.

Note:

Power indicator light (LED) must light up. If it does not, refer to the list below for detailed test.

Refer to the connection table of this manual; check the Red and Black test lead with the socket number on the

Diagnostic Connector, Is there an incorrect or weak connection?

Check the power requirement on the Diagnostic Connector. (Must be performed with the ignition ON when connected with 16-pole diagnostic connector at socket 16)

Connect the Yellow test lead to the system diagnostic socket that you use to extract codes.

Refer to this manual or Mercedes Benz maintenance manual for location of the Diagnostic sockets for the type of Diagnostic Connector fitted to the vehicle and the system capabilities available for code access on the applicable Diagnostic sockets.

2. Turn Ignition ON (KOEO) or Engine at idle (KOER)
