On Board Diagnostic (OBD) - New Beetle 

ITT MARK 20 IE ON BOARD DIAGNOSTIC (OBD), GENERAL INFORMATION 

FUNCTION 

Since the control modules are interconnected with a Controller Area Network bus (CAN-bus), always start 
troubleshooting by pressing buttons -0- and -0- to insert "Automatic Test Sequence" address word 00. This 
checks DTC memory for all control modules in the vehicle, including those that may influence the ABS system 
in case of malfunction. 

On Board Diagnostic (OBD) relates to the electrical and electronic components of the ABS; in other words, 
only malfunctions pertaining to the electrical connections to the control module are recognized (e.g. wheel 
speed sensor, open circuit). 

The 25-pin ABS Control Module (w/EDL) -J104- and the ABS hydraulic unit together form a compact module. 
The control module is equipped with DTC memory, and is located on the left side of the engine compartment. 
The Data Link Connector (DLC) is located left of the steering column under the instrument panel. Only early 
production cars DLC is in the center console below the heating and air conditioning controls. 

The control module recognizes malfunctions during vehicle operation and stores them as Diagnostic Trouble 
Codes (DTC) in permanent memory. The DTCs remain in memory if the voltage from the battery is interrupted.

Sporadic malfunctions will also be recognized and stored. If these do not occur again within the next 50 vehicle 
starts and driving cycles DTC memory will be erased (with the exception of "Control Module Malfunctioning").

Sporadic malfunctions are identified as such by "/SP" appearing on the VAG1551 Scan Tool (ST) display. 

After switching the ignition on and/or starting the engine, ABS warning light -K47- and brake system warning 
lamp -K118- (red) lights up for approx. 2 seconds. During this period a test sequence (self-test) is run in the 
control module, checking the following: 

z

Voltage supply (at least 10.0 volts)  

z

Control module, including valve windings  

z

Wheel speed sensor; electrical check fully completed at 20 km/h (approx. 13 mph)  

z

Control module coding  

z

If after driving off and exceeding a speed of approx. 20 km/h (approx. 13 MPH) the speed signal is not 
OK. The ABS warning light -K47- will light up again.  

VAG1551 Scan Tool (ST) or tester VAS 5051 

The On Board Diagnostic (OBD) program must be initiated at the start of troubleshooting. Electrical 
malfunctions which influence braking characteristics will be stored, and can only be checked with the
