Was bedeutet der Fehlercode?
The transmission control module (TCM) has seen the signal from the position sensor for shift fork 2 change too quickly. The fault concerns that sensor, but whether the cause is in the sensor or in the transmission is shown by the other fault codes present.
Mögliche Ursachen
- Damaged position sensor
- Incorrect voltage supply to the sensor
- Damaged transmission control module (TCM)
Was Sie tun können
- 1Read out the fault codes from the transmission control module again to see whether the fault is in the transmission or in the mechatronic unit
- 2With diagnostic equipment, look at the position value for shift fork 2 in live data and see whether it changes unevenly when the gears are engaged
- 3If fault code TCM-042B is set, the cause is outside the mechatronic unit and a workshop should replace the transmission
- 4If any sensor code TCM-0408, TCM-0409 or TCM-040D is set but not TCM-042B, a workshop should replace the mechatronic unit
- 5If none of these codes is set, a workshop should check the input shaft speeds and the counter values to decide between a sensor and a mechanical fault
Symptome, die Sie bemerken können5
- Check engine light comes on or behaves abnormally
- Text window with yellow warning symbol and message
- Gear changes take too long to complete, sometimes or all the time
- Gears shift too early, too late or too often, sometimes or all the time
- No movement forward or in reverse with a gear selected
