Was bedeutet der Fehlercode?
The CEM supplies the left brake light, which is the emergency brake light, directly from its own output. The code is set when a faulty signal lasts for a while with the brake light not activated. The fault can lie in a poor connection, a break in the supply wire, or a supply that is in contact with battery voltage.
Mögliche Ursachen
- Contact resistance, oxidation or a loose connection at the connectors
- Open circuit in the voltage supply wire
- The voltage supply is short-circuited to battery voltage
Was Sie tun können
- 1Check the fuses for the tail and brake lights. They should be intact
- 2Switch on the tail lights and press the brake with the ignition on. Check that the left lamp lights and goes out as it should
- 3Check the connectors at the lamp housing and in the rear wiring for oxidation, looseness and contact resistance
- 4With the ignition off, use a multimeter to check that the supply wire is unbroken
- 5If the fault returns, have a workshop with diagnostic equipment check the voltage supply
Symptome, die Sie bemerken können2
- The tail light or brake light does not work
