Function<br />

As the control modules are interconnected<br />

with a data bus wire, always start<br />

troubleshooting by the Diagnostic Trouble<br />

Code (DTC) memories of all the control<br />

modules in the vehicle.<br />

This occurs in "Automatic test sequence"<br />

and is activated with key function 00.<br />

When doing this, check to see if there are<br />

DTCs stored which may influence the ABS.<br />

The On Board Diagnostic (OBD) relates to<br />

the electrical/electronic part of the ABS, in<br />

other words only malfunctions via the<br />

electrical connection to the control module<br />

are recognized (e.g. speed sensor open<br />

circuit).<br />

The 47 pin ABS Control Module (w/EDL) -<br />

J104- forms with the hydraulic unit a<br />

compact unit. The unit is located on the left<br />

of the engine compartment. The control<br />

module is equipped with a DTC memory.<br />

The Data Link Connector (DLC) is located in<br />

the center console below the heating/air<br />

conditioning controls.<br />

The control module recognizes malfunctions<br />

during vehicle operation and stores them in<br />

a permanent memory, the contents of which<br />

remain even during periods of no battery<br />

voltage.<br />
