Co oznacza ten kod błędu?
The rear electronic module (REM) reads the signal from the seat belt reminder sensor in the passenger seat. If that signal is too high, the code is set. The cause can be a signal wire shorted to supply voltage or a defective sensor, and a general warning lamp then lights.

- 2Check the connectors at the rear electronic module and at the seat belt reminder sensor in the passenger seat for oxidation, damage and loose contacts
- 3Look for an intermediate connector in the wiring to the sensor and check it
