General Usage Notes

The OB15 Code Scanner can display available fault codes from Mercedes Benz vehicles

fitted with 8-pole, 16-pole and 38-pole Diagnostic Connectors. The Red wire from the

scanner is for powering up the unit and is taken either from the power source socket on the

Diagnostic Connector, if available, or from the vehicle battery, using the extension cable

supplied. The Black earth wire from the scanner is grounded to the earth socket on the

Diagnostic Connector. The Yellow wire from the scanner is used to read the codes from the

Diagnostic Connector.

The P/N 15-C2 diagnostic cable must be used with the P/N 15-C2-1 diagnostic cable for the

38-pole vehicle diagnostic connector.

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 OB15-11 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 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 Benzmaintenance manual for location of the Diagnostic socketsfor thetype

of Diagnostic Connector fitted to the vehicle and the system capabilities available for code access on the

applicable Diagnostic sockets.

Press the

key to scroll through the fault codes

xx . The display will cycle to the first code after

the last code is displayed. When there are no faults in the system,

0 will be displayed on the screen.

There are 5 digital numbers for fault code for the ME-SFI control system, the fault code will

automatically display 1 digital number first then 4 digital numbers later. For example, the fault

code 1234 will display C 0 then 1 2 3 4 . C 0 stands for (Power-train system)

5678 will display C 1 then 5 6 7 8 . C 1 stands for (Chassis system)

0110 will display C 2 then 0 1 1 0 . C 2 stands for (Body system)

4321 will display C 3 then 4 3 2 1 . C 3 stands for (Unspecified system)

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 recordsthe number of times a component fails. When a certain number of failureshasoccurred

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.
