C0010 03

* Ignition ON.

* System and ignition voltage is above 9 volts.

* The system enable relay is ON.

C0010 04

* Ignition ON.

* System and ignition voltage is above 9 volts.

* The system enable relay is ON.

* The pump motor has been commanded OFF for 2 seconds.

C0010 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 03

The EBCM detects an open in the pump motor driver or supply when the motor is commanded on and if the motor feedback is below 50% of the

system voltage for 10 msec.

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 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 an open circuit, binding or stalled pump motor.

Actions Taken when the DTC Sets

* The EBCM disables the antilock brake system (ABS), traction control system and StabiliTrak for the duration of the ignition cycle.

* A driver information center message and/or a warning indicator may be displayed.

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 40 consecutive drive cycles.
