Was bedeutet der Fehlercode?
The transmission control module (TCM) has found that the clutch torque it has calculated for the clutches does not match the engine torque. The transmission has two clutches, clutch 1 for odd gears and clutch 2 for even gears. The fault may come from an incorrect torque signal from the engine, but it may also be in the transmission.
Mögliche Ursachen
- Damaged clutch unit
- Incorrect engine torque
Was Sie tun können
- 1Read out the fault codes from both the transmission and engine control modules and check whether fault code TCM-04A2 is set; trace it if so
- 2Check the engine control module first, since an engine fault that affects torque or the torque signal can cause this code
- 3Check whether the transmission control module has other fault codes that may have the same cause, for example for pressure sensors, speed sensors or the solenoids, and trace those first
- 4If the fault-tracing shows a fault in the transmission, it must be replaced; otherwise the clutch unit may be damaged and a workshop should replace it
Symptome, die Sie bemerken können2
- Gear changes take too long to complete, sometimes or all the time
- Gears shift hard or jerky, sometimes or all the time
