Co oznacza ten kod błędu?
The lane keeping aid (LKA) is receiving incorrect or unreasonable information from the forward sensing module (FSM), and the fault has been active for a while. The code is a knock-on fault: it shows the fault lies in another control module, which must be fixed first. The code can be cleared once the root fault has been repaired.
Możliwe przyczyny
- Poor contact at a connector, from resistance or oxidation
- Brief open circuit or short circuit in the CAN cable between the power steering control module (PSCM) and the forward sensing module (FSM)
- Open circuit or interference in the communication wiring between the PSCM and the FSM
- Interference or a brief open circuit in the CAN network
- Damaged forward sensing module (FSM)
Co możesz zrobić
- 1Start the fault search in the control module that sends the information, since the root fault is there
- 2If you have a diagnostic tool: first check for faults in the FSM, and clear this code only after the root fault is repaired
- 3Check that the connectors at the forward sensing module are firmly seated and clean
- 4Check that the wiring between the PSCM and the FSM is not chafed or pinched
- 5Safety note: lane keeping and steering are safety systems, so have a workshop carry out the rest of the fault search
Objawy, które możesz zauważyć3
- Text window with warning symbol and text message
- The lane keeping assistant does not work
- The lane departure warning does not work
Na co może wpływać usterka1
- The lane keeping assistant (LKA) is disabled while the fault is active
