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.

OB15-11 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 OB15-11 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 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.
B.

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

Operating the CS1000 - Mercedes Benz
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)

ANALOG TEST PROCEDURES
1.

Ignition in the KOEO position (Key On Engine Off).

2.

Choose system

3.

Place test probe (yellow) in pin-out for specific analog test.

DIGITAL TEST PROCEDURE
1.

Ignition in the KOEO position (Key On Engine Off)

2.

Choose system

3.

Place test probe (yellow) in pin-out for Digital test.

4.

If any system does not respond, test it using the Analog Test Procedure.

2.

*Some early LH Injection and Diagnostic Module systems may not respond to the digital test.

4. Read Fault Codes
Press the READ key to begin to read the fault codes for the system selected. The scanner will scan all of
the fault codes and keep them in memory.



When reading Digital Fault Codes the scanner will display a U 1 or a U 2 indicating the type of
digital system it has discovered. Refer to the U codes displayed on the top of the code pages to
identify the system.

READ
Press the NEXT 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.

6. Clearing Fault Codes
After repairs have been carried out reread the codes. After rereading the codes press the CLEAR key to
erase all of the fault codes from the control unit memory. When there are no faults in the system, either 
1 (Impulse or analog systems) or  2 (digital systems) will be displayed on the screen.
