DTC C0110

Circuit Description

Ground is continuously supplied to the low side of the ABS pump motor. The EBCM activates the ABS pump by supplying battery voltage to the high side of the motor.

Conditions for Running the DTC

- The ignition is ON.
- The vehicle speed is greater than 6 km/h (4 mph).

Conditions for Setting the DTC

The EBCM detects an open pump motor circuit, a shorted pump motor, or a seized pump motor or ABS pump.

Action Taken When the DTC Sets

- The TCS operates with engine torque reduction ability only.
- The ABS indicator turns ON.
- The message center displays the service stability system message.

Conditions for Clearing the DTC

The Conditions for Setting the DTC are no longer present and you use the scan tool Clear DTC's function.

Diagnostic Aids

Separate the EBCM from the BPMV in order to inspect for corrosion or any other condition that may cause a poor connection at the pump motor connector.
Refer to Electronic Brake Control Module (EBCM) Replacement (w/ JL4) Electronic Brake Control Module (EBCM) Replacement (w/o JL4) and Testing for Intermittent and Poor Connections. If severe corrosion or other damage exists, the BPMV or the EBCM may need to be replaced.
