Circuit/System Verification
1. Engine running with the hood open, accessories OFF, measure and record the battery voltage. The voltage should be between 12.6-15.0 V.
瀚慖f not within the specified range, refer to DC Power Conversion Test ().
2. Observe the scan tool transmission data ignition voltage parameter. The reading should be between 12.6-15.0 V.
Circuit/System Testing
1. Ignition OFF, disconnect the X1 Q8 control solenoid assembly harness connector at the transmission.
2. Ignition ON, verify that a test lamp illuminates between the ignition voltage circuits listed below and ground.
* Terminal 4
* Terminal 12
瀚慖f the test lamp does not illuminate, test the ignition circuit for a Short to Ground or an Open/High Resistance.
3. If all circuits test normal, replace the Q8 control solenoid valve assembly.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
