Circuit/System Testing

Ignition OFF, remove the Q8 Control Solenoid Valve Assembly.
NOTE: You must perform Circuit/System Verification first.
Verify the Q8 Control Solenoid Valve Assembly is not contaminated with any debris and clean as necessary. Refer to Control Solenoid Valve and Transmission Control Module Assembly Inspection .
- If contaminated
  Repair as necessary.
- If not contaminated
Verify the resistance is within the specified range for each solenoid valve listed in the Control Solenoid Valve and Transmission Control Module Assembly Inspection .
- If the resistance is not within range
  Replace the Q8 Control Solenoid Valve Assembly.
- If the resistance is within range
Place the Q8 Control Solenoid Valve Assembly on a clean work surface near the transmission assembly.
Connect the DT-48616-10 adapter harness between the vehicle harness connector and the Q8 Control Solenoid Valve Assembly connector. Ignition ON.
Verify the scan tool parameters listed below do not display Malfunction when commanding Shift Solenoid Valve 1 On and Off:
NOTE: If Shift Solenoid Valve 1 is not commanded from the Transmission Solenoid Performance Test, High Side Driver 1 will not be commanded On and the circuit test status will not run.
- Shift Solenoid Valve 1 Control Circuit Low Voltage Test
- Shift Solenoid Valve 1 Control Circuit Open Test
- Shift Solenoid Valve 1 Control Circuit High Voltage Test
- If Malfunction is displayed
  Replace the Q8 Control Solenoid Valve Assembly.
- If Malfunction is not displayed
All OK.
