Remove the component : Q8 Control Solenoid Valve Assembly
Verify the condition does not exist : Contamination with metallic debris
- If a condition exists
  Repair or replace as necessary.
- Go to next step : If no condition exists
Verify the resistance is within the specified range for each solenoid valve. - Refer to : Control Solenoid Valve and Transmission Control Module Assembly Inspection
- If the resistance is not within range
  Replace the component : Q8 Control Solenoid Valve Assembly
- Go to next step : If the resistance is within range
Test for infinite resistance between the test points : Each terminal of the component - Solenoid Valve & The component's housing
- If less than infinite resistance
  Replace the component : Q8 Control Solenoid Valve Assembly
- Go to next step : If infinite resistance
Install the special tool : DT-48616-10 Adapter Harness @ Q8 Control Solenoid Valve Assembly & Vehicle wiring harness X1
Ignition - On / Vehicle - In Service Mode
Perform the scan tool control function : High Side Driver 1 - On and Off
Verify the scan tool parameter :
- High Side Driver 1 Circuit Low Voltage Test Status = OK or Not Run
- High Side Driver 1 Circuit Open Test Status = OK or Not Run
- High Side Driver 1 Circuit High Voltage Test Status = OK or Not Run
- If not the specified state
  Replace the component : Q8 Control Solenoid Valve Assembly
