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 should be 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.

PPT Y ABS MODULE DTC FAULT TRIGGER CONDITIONS

DTC	Description	Fault Trigger Conditions
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.
