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.
