Hva betyr feilkoden?
The upper electronic module (UEM) reports a low signal level on the movement sensor's supply wire while the alarm is set. The code is set when this happens. The fault comes from the sensor's supply being short-circuited to ground, or from a defective sensor.
Mulige årsaker
- The sensor's voltage supply is short-circuited to ground
- Defective sensor
Hva du kan gjøre
- 1Read off the code, clear it and check whether it returns.
- 2Look for chafed or pinched spots on the sensor's wire and connectors.
- 3Use a multimeter to check that the supply wire to the sensor has no contact with ground (the bodywork).
- 4Check that the connectors at the sensor and at the upper electronic module are firmly seated and not corroded.
- 5If no fault is found, have a workshop replace the sensor.
Symptomer du kan merke1
- The alarm does not respond to the movement sensor
