C1262

DTC C1261-C1274





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

Conditions for Running the DTC
^ The solenoid power 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 for the duration of the ignition cycle.
^ The ABS indicator turns ON.
^ The Traction Control indicator turns ON.
^ The DIC displays the Service Stability System message.

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 50 consecutive drive cycles.

Diagnostic Aids
^ Make sure the integrity of the connection between the EBCM and the BPMV is secure, tight, and free from corrosion.
^ The solenoid valves are internal to the BPMV and can not be serviced individually. The solenoid valve circuits are internal to the EBCM and can not be serviced individually.

Test Description
The numbers below refer to step numbers on the diagnostic table.
3. Tests the resistance value of the solenoid.
4. Tests for a short to ground in the BPMV.
5. Verifies that the DTC is current.
