Circuit/System Verification
- Engine idling at the normal operating temperature.
- Verify the scan tool Transmission Fluid Temperature parameter is between -254 and +254°C (-425 and +489°F).
- If not between -254 and +254°C (-425 and +489°F)
Replace the Q8 Control Solenoid Valve Assembly.
- If between -254 and +254°C (-425 and +489°F)
- If not between -254 and +254°C (-425 and +489°F)
- Verify the scan tool Transmission Fluid Temperature parameter increases greater than 2°C (3.6°F) after operating the vehicle at 64 km/h (40 mph) for 10 min.
- If the temperature does not increase greater than 2°C (3.6°F)
Replace the Q8 Control Solenoid Valve Assembly.
- If the temperature increases greater than 2°C (3.6°F)
- If the temperature does not increase greater than 2°C (3.6°F)
- Verify the scan tool Transmission Fluid Temperature and the TCM Temperature parameters are within 20°C (36°F).
- If the temperatures are not within 20°C (36°F)
Replace the Q8 Control Solenoid Valve Assembly.
- If the temperatures are within 20°C (36°F)
- If the temperatures are not within 20°C (36°F)
- Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
- Verify the DTC does not set.
- If the DTC sets
Replace the Q8 Control Solenoid Valve Assembly.
- If the DTC does not set
- If the DTC sets
- All OK.
