C0114

The pump motor is an integral part of the Brake Pressure Modulator Valve (BPMV). The system relay and pump motor driver is located in the Electric Brake and Traction Control Module (EBTCM). The system relay supplies power to the solenoids and pump motor whenever the ignition switch is in the RUN position. The pump motor driver switches the pump motor on during ABS operation.

CODE PARAMETERS
DTC C0114 will set if:
- System voltage is greater than 8 volts, the system relay is on and the pump is commanded off.
- Voltage across the pump is between 1.6 and 10 volts for 2 seconds.
When the trouble code sets, ABS is disabled and the antilock telltale is turned on.
Dynamic rear proportioning (DRP) will only have the hold function.

DIAGNOSTIC AIDS
- It is very important to thoroughly inspect wiring components and connectors. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.
Possible causes for DTC C0114 to set:
- Pump motor open.
- Pump motor (internal) circuit open.
