Pinpoint Test Y: Abs Module Internal Fault Concern
Normal Operation and Fault Conditions
The ABS module carries out self tests during operation, the module also monitors various inputs and compares the values to what is expected. If the values received are out of range, are not what is expected, or if any of the self tests fail, the ABS module sets a DTC.
