Fault-Tracing Information
Fault-tracing
Checking oil temperature
- Ignition on.
- Read off the oil temperature.
Check that the oil temperature is within its permitted range. Compare it to the automatic transmission temperature.
Note! The transmission temperature sensor is inside the control system and may be affected by the heat given off by the solenoids.
Oil Temperature Sensor:
Is the temperature reading OK?
Yes - Checking the wiring and component
No - Checking the components and wiring
-------------------------------------------------
Verification

Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off.
- Reinstall the connectors, components etc.
- Ignition on.
- Start the engine. Allow the engine to idle.
- Read off the oil temperature.
Check that the oil temperature is within its permitted range. Compare it to the automatic transmission temperature.
Note! The transmission temperature sensor is inside the control system and may be affected by the heat given off by the solenoids.
Oil Temperature Sensor:
Is the temperature reading OK?
Yes - VERIFIED
No - VERIFICATION FAILED

Information
Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit fault-tracing
No - Attempt New Test
------------------------
Attempt New Test - Checking oil temperature
-------------------------------------------------
Checking the components and wiring
- Open the transmission control system.
Check the signal cable. Check for a short-circuit to ground.
Remedy as necessary.

Continue - Verification
-------------------------------------------------
Checking the wiring and component
The probable cause of the diagnostic trouble code (DTC) was the transmission being subjected to high loads and high temperatures. It is therefore important to change transmission fluid and to check the function of the transmission.
Hint: If no fault is found check the oil temperature sensor. See: Checking internal components of the transmission, B6304T4, TF-80SC AWD, B6324S5, TF-80SC AWD, B6324S5, TF-80SC, B6324S4, TF-80SC AWD, B6324S4, TF-80SC Checking Internal Components Of The Transmission

Resetting the oil quality counter
Resetting the "Transmission fluid change" counter
Checking the function
Hint: The transmission control module (TCM) has a counter for fluid quality that counts the number of times the transmission is subjected to too hard a load or too high an ambient temperature. If the counter is not reset during draining/replacement, there is a risk that a diagnostic trouble code will be set under the wrong conditions. Thus, it is important that the counter for transmission fluid change be reset.
Note! This only applies when the transmission oil is changed and when the oil is changed during repairs to the transmission's temperature sensor.
- Ignition on.
Click on the VCT2000 symbol to reset the counter.
