C0110

DTC C0110

Circuit Description
Ground is continuously supplied to the low side of the ABS pump motor. The electronic brake control module (EBCM) activates the ABS pump by supplying battery voltage to the high side of the motor.

DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC C0110 Pump Motor Circuit

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 EBCM disables the ABS/vehicle stability enhancement system (VSES).
^ The traction control system (TCS) operates with engine torque reduction ability only.
^ The ABS indicator turns ON.
^ The stability indicator turns ON.
^ An ECE 13 response may occur.

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

Diagnostic Aids
Separate the EBCM from the brake pressure modulator valve (BPMV) in order to inspect for corrosion or any other condition that may cause a poor connection at the pump motor connector. If severe corrosion or other damage exists, the BPMV or the EBCM may need to be replaced.








Test Description
The number below refers to the step number on the diagnostic table.
4. This step tests for high resistance in the battery positive voltage circuit by verifying that an excessive voltage drop does not occur in the circuit.
