Pinpoint Test An: Stability Control Sensor Initialization Fault

Refer to: VEHICLE DYNAMIC SYSTEMS for schematic and connector information.

Normal Operation and Fault Conditions 

The ABS module monitors various inputs and compares the values to what should be expected. If the values received are out of range or not what is expected, the ABS module sets a DTC. When a new ABS module or RCM is installed, the stability control sensors in the RCM must be initialized. This is accomplished using a diagnostic scan tool to run the ABS Calibration routine.
