Co oznacza ten kod błędu?
The CEM supplies the left emergency brake light directly from one output. The code is set when a faulty signal lasts for a while with the brake light activated. The cause is a voltage supply wire shorted to ground.
Możliwe przyczyny
- The voltage supply wire is short-circuited to ground
Co możesz zrobić
- 1Press the brake with the ignition on. If the left light stays dark the fault is likely permanent; if it worked before, it is intermittent
- 2Check that the brake light fuse is intact
- 3With the ignition off, use a multimeter to check that the voltage supply wire has no contact with ground (the body)
- 4Look for chafing and pinched spots where the wire runs in the rear wiring harness
- 5If the fault returns, have a workshop with diagnostic equipment check the circuit
Objawy, które możesz zauważyć2
- The left brake light and tail light do not work
- The lights stay constantly on
