Roll Over Sensor Diagnosis and Testing: Notes

The sensor performs a self check every time the ignition key is switched on. All components of the sensor are checked including the output stages for roll bar triggering. If a fault is detected, the warning lamp in the cluster is illuminated and the fault is stored in the memory of the RPS Sensor.

In the event of a power failure, capacitors in the sensor can still trigger the solenoids for approximately 5 seconds.
