Circuit/System Verification
- Ignition - On/Vehicle - In Service Mode
- Verify the scan tool parameter: Transmission Fluid Temperature = -39 to 149°C (-38 to 300°F)
- If not between -39 and 149°C (-38 and 300°F)
Refer to: Circuit/System Testing
- Go to next step: If between -39 and 149°C (-38 and 300°F)
- If not between -39 and 149°C (-38 and 300°F)
- Verify DTC P0711 is not set.
- If the DTC is set
- Verify the condition does not exist: Incorrect fluid level or condition - Refer to: Transmission Fluid Level and Condition Check
- If a condition exists - Repair or replace as necessary
- Go to next step: If no condition exists
- Operate the cold vehicle above 64 km/h (40 MPH) for 10 min.
Verify the scan tool parameter: Transmission Fluid Temperature = Temperature increases greater than 15°C (27°F)
- If the temperature does not increase 15°C (27°F) or greater - Refer to: Circuit/System Testing
- Go to next step: If the temperature increases greater than 15°C (27°F)
- All OK.
- Go to next step: If the DTC is not set
- Verify the scan tool parameter: Transmission Fluid Temperature = The value should not spike or drop out.
Perform the action while monitoring the parameter:
- Wiggle the harness and connector(s): X1 @ T12 Automatic Transmission
- Wiggle the harness and connector(s): K71 Transmission Control Module
- If the value spikes or drops out
Repair as necessary - Wiring/Terminal(s)/Electrical Connector(s)
- Go to next step: If the value does not spike or drop out
- 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
Refer to: Circuit/System Testing
- Go to next step: If the DTC is not set
- If the DTC sets
- All OK.
