Hva betyr feilkoden?

The transmission control module (TCM) has found that one clutch fails to open. The transmission has two clutches, clutch 1 for odd gears and clutch 2 for even gears, and the control module opens a clutch by releasing its pressure. The fault may come from a missing or incorrect signal from the engine control module or from a damaged clutch unit.

Mulige årsaker

Signal from the engine control module is missing or incorrect
Damaged clutch unit

Hva du kan gjøre

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 a missing or incorrect engine signal can cause this code
3If no fault is found in the engine control module, the clutch unit may be damaged and a workshop should replace it
4Fault-tracing may also show a fault in the transmission, in which case the transmission must be replaced; have a workshop do this
