Engine immobilisation and anti-theft alarm
- Thiese functions are realized by the Alarm-ECU which measures some
sensors en switches and depending on the setting will produce
immobilisation and alarm.
- Interior light and central door locking are controlled by the alarm
ecu [AS10].
- Immobilisation and alarm are by flips
The Nanocom diagnostic unit can be used to measure and set AS10 values.
