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 should be expected, the ABS module sets a DTC.

PPT Y ABS MODULE DTC FAULT TRIGGER CONDITIONS

DTC	Description	Fault Trigger Conditions
C1A99:14	Pressure Sensor: Circuit Short to Ground or Open	Sets when the ABS module detects master cylinder pressure sensor within the ABS module has failed.
C1A99:25	Pressure Sensor: Signal Shape/Waveform Failure	Sets when the ABS module detects master cylinder pressure sensor within the ABS module has failed.
C1A99:28	Pressure Sensor: Signal Bias Level Out of Range/Zero Adjustment Failure	Sets when the ABS module detects master cylinder pressure sensor within the ABS module has failed.
U2007:1B	Valve(s): Circuit Resistance Above Threshold	Sets when the ABS module detects high or low resistance in one or more of the HCU valve coils.
U2007:49	Valve(s): Internal Electronic Failure	Sets when the ABS module detects an electrical failure (open or short) from one or more of the HCU valve coils.
U2007:4B	Valve(s): Over Temperature	Sets when the ABS module detects excessive temperature within the ABS module.
U3000:44	Control Module: Data Memory Failure	Sets when the ABS module detects an internal fault.
U3000:45	Control Module: Program Memory Failure	Sets when the ABS module detects an internal fault.
U3000:46	Control Module: Calibration/Parameter Memory Failure	Sets when the ABS module detects an internal fault.
U3000:47	Control Module: Watchdog/Safety Failure	Sets when the ABS module detects an internal fault.
U3000:48	Control Module: Supervisor Software Failure	Sets when the ABS module detects an internal fault.
U3000:49	Control Module: Internal Electronic Failure	Sets when the ABS module detects an internal fault.
U3000:4B	Control Module: Over Temperature	Sets when the ABS module detects excessive temperature within the ABS module.
