REPAIR PROCEDURE
INTERNAL CONTROL MODULE ERRORS RELATING TO THE ABS MODULE
NOTE:
"Internal control module errors" may be the result of components within the ABS/Dynamic Stability Control (DSC) module. These may include
problems with the microprocessor, power supply or driver circuit (e.g. valve driver circuits). Internal control module errors are usually a good
indication of a genuine control module fault, but can sometimes be logged as a result of other faults that are external to the control module.
NOTE:
After following the guidance in this bulletin, if no definite cause was found for an internal control module DTC, and the vehicle does not have a
history of repeat failures, and all DTCs have been cleared and have not returned after a test drive of at least 10 miles (16km), the vehicle can be
returned to the customer.
IDENTIFY AND RESOLVE FAULTS
NOTE:
A Midtronics battery charger PSC550 must be connected to the vehicle battery during diagnostic sessions.
