C1265








Circuit Description
The system relay is energized when the ignition is ON. The system relay supplies voltage to the solenoid valves and the pump motor. This voltage is referred to as the system voltage. The EBCM controls the solenoid valve by grounding the control circuit.

Conditions for Running the DTC
^ The system voltage is greater than 8.0 volts.
^ The ignition voltage is greater than 9.0 volts.

Conditions for Setting the DTC
The commanded state of the driver and the actual state of the control circuit do not match for 0.03 seconds.

Action Taken When the DTC Sets
If equipped, the following actions occur:
^ The EBCM disables the ABS/TCS/VSES/DRP for the duration of the ignition cycle.
^ The ABS indicator turns ON.
^ The TRACTION CONTROL indicator turns ON.
^ The DIC displays the SERVICE STABILITY SYS message.
^ DTC C1248 also sets.
^ The red BRAKE warning indicator turns ON.

Conditions for Clearing the DTC
^ The condition for the DTC is no longer present (the DTC is not current) and you used the scan tool Clear DTC function.
^ The condition for the DTC is no longer present (the DTC is not current) and you used the On-Board Diagnostics Clear DTC function.
^ The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Diagnostic Aids
The solenoid valve circuit is internal to the EBCM. The solenoid valve circuit is not diagnosable external to the EBCM. The DTC sets when there is a malfunction in the solenoid circuit internal to the EBCM.

Test Description
The number below refer to the step number on the diagnostic table.
2. This step determines whether the DTC is current.
