Fault-Tracing Information

Fault-tracing

Checking lock-up solenoid SLU




- Ignition on.
- Activate solenoid SLU by clicking on the VCT2000 symbol.
Read off the current through the solenoid SLU circuit. The current should oscillate between 100 and 950 mA.
The fault is permanent if the current does not change.
If the current changes, this is an indication that the fault was present previously but is not active at the moment, i.e. an intermittent fault.

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








- Ignition off.
- Reinstall the connectors, components etc.
- Ignition on.
- Activate solenoid SLU by clicking on the VCT2000 symbol.
Read off the current through the solenoid SLU circuit. The current should oscillate between 100 and 950 mA.

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

Checking the components and wiring




- Ignition off.
- Open the transmission control system.
Check the cable for a short-circuit to supply voltage.
Take readings between:
- Transmission connector #B9 and the connector for solenoid SLU #1.
- Transmission connector #B4 and the connector for solenoid SLU #2.
Also check the cables for a short-circuit to each other.

Hint: If no fault is found in the wiring, check solenoid SLU. 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 no fault is found in the wiring or the component replace the control system.
Remedy as necessary.

Resetting the adaptation and oil quality counter





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.
