Function
As the control modules are interconnected with
a data bus wire, always start troubleshooting by
the Diagnostic Trouble Code (DTC) memories
of all the control modules in the vehicle.
This occurs in "Automatic test sequence" and is
activated with key function 00.
When doing this, check to see if there are
DTCs stored which may influence the ABS.
The On Board Diagnostic (OBD) relates to the
electrical/electronic part of the ABS, in other
words only malfunctions via the electrical
connection to the control module are
recognized (e.g. speed sensor open circuit).
The 47 pin ABS Control Module (w/EDL) -J104-
forms with the hydraulic unit a compact unit.
The unit is located on the left of the engine
compartment. The control module is equipped
with a DTC memory. The Data Link Connector
(DLC) is located in the center console below
the heating/air conditioning controls.
The control module recognizes malfunctions
during vehicle operation and stores them in a
permanent memory, the contents of which
remain even during periods of no battery
voltage.
