Transmission/Control Solenoid Valve and Transmission Control Module Assembly Inspection).
3. Place the Q8 control solenoid valve assembly on a clean work surface near the transmission assembly.
4. Connect DT-47825-10 - jumper harness between the vehicle wire harness electrical connector, and the Q8 control solenoid valve assembly
electrical connector.
5. Ignition ON, verify with a scan tool the following test status parameters display OK:
* Pressure Control Solenoid Valve 5 Performance Test Status
* Pressure Control Solenoid Valve 5 Control Circuit High Voltage Test Status
* Pressure Control Solenoid Valve 5 Control Circuit Low Voltage Test Status
瀚慖f any test status parameter displays Fault or Malfunction, replace the Q8 control solenoid valve assembly.
Repair Instructions
