Conditions for Running the DTC

C0110 04

* System and ignition voltage is above 10.5 volts.

* The system enable relay is ON.

* The pump motor has been commanded OFF for 2.5 seconds.

C0110 03 or C0110 61

* Ignition ON.

* The system enable relay is ON.

* The pump motor has been commanded ON, OFF and ON again.

Conditions for Setting the DTC

C0110 04

The EBCM detects an open in the pump motor circuit when the feedback voltage remains greater than 0.75 volt for more than 50 msec.

C0110 03 or C0110 61

The pump motor continues to rotate briefly after activation creating a feedback voltage. The EBCM sets the code if the measured feedback voltage

indicates a binding or stalled pump motor.

Action Taken When the DTC Sets

* The EBCM disables the ABS/TCS/vehicle stability enhancement system (VSES) for the duration of the ignition cycle.

* The ABS indicator turns ON.

* The Traction Control indicator turns ON.

* The driver information center (DIC) displays the Service Stability System message.

Conditions for Clearing the DTC

* The condition for the DTC is no longer present.

* Operate the vehicle at speeds greater than 15 km/h (10 mph) to complete the self test, and the EBCM will turn off the ABS indicator.

* The EBCM clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
