Fault-Tracing Information






Fault-tracing

Checking the function

Warning! Ensure that the vehicle is safely raised. Check that no objects are caught in the tire treads.

Caution! On vehicles with four-wheel-drive, the tests should be carried out with the vehicle raised so that all four wheels can rotate freely with attachments far out on the link arms so that the drive shafts are not damaged.

Note! If the vehicle has TRACS or TC (STC, DSTC), this function must be disabled. This is carried out by removing the fuse for the brake system pump motor in the engine compartment relay and fusebox. Note that this will generate diagnostic trouble codes in the brake control module (BCM). These diagnostic trouble codes must be erased before the vehicle is returned to the customer.




- Raise the vehicle so that the drive wheels can rotate freely.
- Start the engine. Allow the engine to idle.
- Shift the gear selector to position D so that the drive wheels begin to rotate.

Note! Ensure that the wheels are not rotating when the gear selector is moved.

Read off the transmission output speed.
Check that the transmission speed is updated.
If the transmission input speed updates correctly it means that the fault was present previously but is not active now. There is an intermittent fault.
If the transmission input speed does not update correctly it means that the fault is permanent.

Checking the wiring and sensors








- Ignition off.
- Disconnect the transmission connector.
- Transmission control module (TCM) disconnected.
Check connector B (22-pin) for the transmission control module (TCM). Check for damaged or pressed in pins. Check for contact resistance and oxidation.

Hint: Check the transmission speed 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

If a faulty value is measured in the test above, open the control system for the transmission and fault trace the wiring and components.
If the wiring is faulty, replace the cable harness.
If the sensor is faulty, replace the transmission.
Remedy as necessary.

Verification

Hint: After carrying out the repair, check that the fault has been remedied.

Caution! On vehicles with four-wheel-drive, the tests should be carried out with the vehicle raised so that all four wheels can rotate freely with attachments far out on the link arms so that the drive shafts are not damaged.

Warning! Ensure that the vehicle is safely raised. Check that no objects are caught in the tire treads.

Note! If the vehicle has TRACS or TC (STC, DSTC), this function must be disabled. This is carried out by removing the fuse for the brake system pump motor in the engine compartment relay and fusebox. Note that this will generate diagnostic trouble codes in the brake control module (BCM). These diagnostic trouble codes must be erased before the vehicle is returned to the customer.








- Ignition off.
- Reinstall the connectors, components etc.
- Raise the vehicle so that the drive wheels can rotate freely.
- Start the engine. Allow the engine to idle.
- Shift the gear selector to position D so that the drive wheels begin to rotate.

Note! Ensure that the wheels are not rotating when the gear selector is moved.

- Read off the transmission output speed.
Check that the transmission speed is updated.

Note! Diagnostic trouble codes may be stored in the brake control module (BCM) when the back wheels are stationary and the front wheels rotate. Erase any diagnostic trouble codes (DTCs) after fault-tracing.





Is the speed updated?

Yes - VERIFIED

No - VERIFICATION FAILED

Resetting the adaptation and the counter for "Transmission oil, replace"





Resetting adaptation

Resetting the adaptation and the counter for "Transmission oil, replace"

Hint: The transmission has torque-regulated, adaptive pressure regulation. The pressure regulator enables the transmission to regulate pressure during each shift to prevent hard shifting. Each shift is assessed by the transmission control module (TCM) and is stored in the internal memory. This makes it possible to compensate for transmission and clutch wear. It is important that the adaptation in the memory is reset so that the transmission works normally after the repair. Because the fluid was changed during the repair, the counter for transmission fluid change must also be reset. If the counter is not reset during draining/replacement, a diagnostic trouble code may be generated under the wrong conditions.

Note! This applies only if the transmission or one of the components in the transmission have been replaced.




- Ignition on.
Click on the VCT2000 symbol to reset the adaptation and counter.
