C1273

CIRCUIT DESCRIPTION
The valve solenoid circuits are supplied with battery power when the ignition is ON. The EBTCM controls the valve functions by grounding the circuit when necessary.

CONDITIONS FOR SETTING THE DTC
The EBTCM senses a discrepancy such as an open, short to ground, or short to voltage in the circuit.

ACTION TAKEN WHEN THE DTC SETS
^ A malfunction DTC is stored.
^ The ABS/TCS/Stabilitrak is disabled.
^ The ABS indicator is turned ON.
^ The TRACTION CONTROL indicator is turned ON.
^ The DIC displays the SERVICE STABILITY SYS message.

CONDITIONS FOR CLEARING THE DTC
^ The condition for DTC is no longer present and you used scan tool Clear DTCs function.
^ The condition for DTC is no longer present and you used the On-Board Clear DTCs function.
^ The EBTCM does not detect the DTC in 50 drive cycles.

DIAGNOSTIC AIDS
Make sure the integrity of the connection between the EBTCM and the BPMV is secure, tight, and free from corrosion.

TEST DESCRIPTION
The numbers below refer to step numbers on the diagnostic table.
3. This step checks the resistance value of the solenoid.
4. This step checks for a short to ground in the BPMV.
7. This step checks for an internal short to voltage.
