Hva betyr feilkoden?

The transmission control module receives the requested torque signal from the engine control module (ECM) over the CAN network. The signal is missing or faulty. The transmission uses it to decide shift points and to adjust system pressure. The fault lies in the engine control module, so fault tracing starts there.

Mulige årsaker

The fault lies in the engine control module (ECM)
A CAN wire that is intermittently broken or shorted, linking the engine module to the transmission module

Hva du kan gjøre

1Read the fault codes in the CEM and the engine control module, and fix them first. Do not clear TCM-C007400 while they are still present
2Have a workshop trace the engine control module and the CAN network with diagnostic equipment
3Clear TCM-C007400 once the root fault is fixed and drive the car to see whether the code returns

Symptomer du kan merke5

Malfunction Indicator Light (check engine) lit or behaving abnormally
Engine stalls at idle when a gear is engaged
Engine stalls when slowing down
Lock-up does not work
Shifts hard or jerky

Hva feilen kan påvirke2

The transmission control module uses the requested torque signal sent from the engine control module on HS-CAN 1
If that signal is also faulty, the transmission control module uses a basic value and the transmission runs an auxiliary program
