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.
REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS C1B11:71 | Pressure Control Valve: Actuator Stuck | Sets when the ABS module detects an unwanted opening or closing of the pressure control valve. This is most likely due to an internal failure of the EBB. |
| ABS U3000:00 | Control Module: No Sub Type Information | Sets when the ABS module detects an internal hardware fault. |
| ABS U3000:49 | Control Module: Internal Electronic Failure | Sets when the ABS module detects an internal hardware fault. |
| ABS U3000:4B | Control Module: Over Temperature | Sets when the ABS module detects an internal hardware fault. |
| ABS U3000:96 | Control Module: Component Internal Failure | Sets when the ABS module detects an internal hardware fault. |
| ABS P1177:64 | Synchronization: Signal Plausibility Failure | The ABS module monitors the linear actuation motor during operations. The rotational speed and current of the motor is monitored when the motor is spinning-down. If the information is not within specifications or if there is no motor movement, this DTC is set. |
