2.3 Rollover Sensor
Rollover sensor module constantly monitors the motion of the vehicle and determines whether the
vehicle is in the safe state or it’s approaching the rollover situation. The rollover sensor module
also performs other tasks such as brake performance monitoring and shock absorber performance
monitoring. The sensor should be mounted close to the rear axle, at the middle of the vehicle. The
connector plug on the rollover sensor should face forward. The sensor should be mounted as
horizontal to the ground, where the bottom of the sensor should face the ground.
Once the sensor is mounted on the vehicle and the connector plug is connected to the dashboard
unit, the service personal should verify the connectivity and also check the orientation angle. If the
vehicle is standing flat, the dashboard unit should display the orientation angle for pitch and roll
axes as close to zero as possible.

2.4 Motion Sensor
Motion sensor (tacho sensor) measures speed and distance travelled by a vehicle. The tacho
sensor is mounted in the gearbox, where it picks up revolutions of gear output that are used to
measure distance travelled by the vehicle and its current speed.

2.5 Calibration
AutoMonitor needs to be calibrated regularly according to the local regulation. The motion sensor
and the rollover sensor both need to be calibrated by a trained workshop technician.
