Rps Diagnosis And Testing
The roll over 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 the roll over bar solenoids. If a fault is detected, the warning lamp in the cluster is illuminated and the fault is logged in the memory of the convertible top control module.
In the event of a power failure, the capacitors in the sensor can still trigger the solenoids for approximately 5 seconds.
The operation of the roll over protection system must be checked as every inspection I & II. The operation of the system is checked using the DIS tester or MoDiC to trigger the deployment of the roll bars. A signal is sent from the Convertible top module to the roll over sensor to activate the system.
The total number of times the system is activated is stored in the memory of the top module. It can be read out though the tester display.
After fifty activations of the system, it must be inspected for wear. Refer to the appropriate article for the proper checking procedures.
