Solenoid valve for lock-up 3 disengage - Open circuit
Check the cable harness on the high voltage side on the solenoid valve actuator box and on the G6 ECU. If several other fault codes indicating open circuit check the low voltage connection on the cable harness for the solenoid valve actuator box and for the G6 ECU. Check the wire between the G6 ECU and the solenoid valve actuator box. The fault can also be inside the solenoid valve actuator box.
What you'll see
No driver-visible symptom recorded.
System reaction
The system will not be able to shift the lockup 3 gear sleeve. If the lockup 3 gear sleeve is engaged, it will be possible to continue in the current gear. If the lockup 3 gear sleeve is not engaged, no gears will be available.
Diagnostic depth
Solenoid valve is disconnected either on the high or the low voltage side. If disconnected on the low voltage side other solenoid valves will also have open circuit fault codes.
Harness, connectors or component has open circuit.
