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.
The U3000:XX Diagnostic Trouble Codes (DTCs) may set along with other ABS Diagnostic TroubleCodes (DTCs). Diagnose all other ABS module Diagnostic Trouble Codes (DTCs) before diagnosing any ABS module U3000:XX Diagnostic Trouble Codes (DTCs). Refer to ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL - SYSTEM OPERATION AND COMPONENT DESCRIPTION .
PPT Y ABS MODULE DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C101F:49 | Generic Valve Failure: Internal Electronic Failure | This DTC sets due to incomplete or improper module programming procedures. |
| C1A08:1C | Pressure Sensor Supply: Circuit Voltage Out Of Range | This DTC sets when the ABS module detects an internal fault. |
