Co oznacza ten kod błędu?
The fault code concerns the engine torque signal on the CAN network, which the transmission control module uses for shift points and system pressure. The signal is indicated as faulty on either HS-CAN 1 or HS-CAN 2. The fault is general and does not say more precisely what type of fault it is; the cause may lie in the engine control module or in the CEM.
Możliwe przyczyny
- Sporadic open or shorted CAN wire between the engine control module and the transmission control module
- Fault in the engine control module (ECM)
- Fault in the central electronic module (CEM)
Co możesz zrobić
- 1Read the fault codes in the engine control module and the CEM, and fix those first
- 2This code can be cleared only after the root fault has been fixed and its fault code cleared
- 3Have a workshop check the CAN network between the engine control module and the transmission control module for open circuits and short-circuits
Objawy, które możesz zauważyć5
- Warning symbol and text message in the display, and the check engine light lit
- Engine stalls when a gear is engaged
- Engine stalls when slowing down
- Lockup does not work
- Gear changes harsh or jerky
Na co może wpływać usterka3
- The transmission control module uses a basic value for the signal
- Adaptation is blocked
- Slip lock-up and automatic engine start/stop are switched off
