Anti-Lock Brake System (ABS) and Stability Control

Diagnosis and Testing).

C1A08:1C Pressure Sensor Supply:

Circuit Voltage Out of Range

The brake system pressure sensor is supplied voltage by the ABS module. The ABS module monitors this output and sets this DTC when the voltage is out of range. DIAGNOSE DTC U3003:16 or U3003:17, before diagnosing C1A08:1C. If DTC U3003:16 or U3003:17 is not present, make sure all ABS module-to- HCU fasteners are tightened to their correct torque specifications. If all fasteners are tightened to their correct torque specifications, INSTALL a new ABS module. REFER to: Anti-Lock Brake System (ABS) Module (206-09 Anti-Lock Brake System (ABS) and Stability Control, Removal and Installation).

Hydraulic Pressure Unit: Calibration / Parameter Memory Failure

The ABS module and HCU should not be swapped between different vehicles. This DTC sets when the identification data stored in the ABS module does not match the identification data from the HCU. Using a diagnostic scan tool, CARRY OUT the Inlet Valve Calibration routine and then the Master Cylinder Isolation Calibration routine. CLEAR the DTC and REPEAT the self-test. If the DTC returns, INSTALL a new ABS module and HCU assembly. REFER to: Hydraulic Control Unit (HCU) (206-09 Anti-Lock Brake System (ABS) and Stability Control, Removal and Installation).

Hydraulic Pressure Unit: Internal Electronic Failure

The ABS module and HCU should not be swapped between different vehicles. This DTC sets when the identification data stored in the ABS module does not match the identification data from the HCU. Using a diagnostic scan tool, CARRY OUT the Inlet Valve Calibration routine and then the Master Cylinder Isolation Calibration routine. CLEAR the DTC and REPEAT the self-test. If the DTC returns, INSTALL a new ABS module and HCU assembly. REFER to: Hydraulic Control Unit (HCU) (206-09 Anti-Lock Brake System (ABS) and Stability Control, Removal and Installation).
