Roll Over Sensor

The rollover sensor is installed in the rear behind the right rear seat back on the rollover cassette. It contains the processing electronics for rollover detection and deployment final stage for triggering the rollover bar solenoids. Two capacitors are also installed for roll bar deployment in the event of a power failure with the system during an a crash. The sensor is connected to the diagnostic link for troubleshooting purposes.

The sensor preforms a self check every time the ignition is switched on. If any faults are detected, the warning lamp in the cluster will illuminate. If possible, the system will trigger the solenoids even though a fault is stored in the fault memory.
