directly to an event record
An event record has been triggered from either an internal
sensor or from an IF Box:
1. If the DVM is not correctly mounted the
accelerometer events may be triggered
inadvertently. Adjust the DVM to the
correct positions for a rear view mirror.
2. Disconnect the Sensor Cable RJ-45
connector from the IF Box and reset the
DVM. If the problem doesn’t re-occur,
check the wiring from the vehicle to the
sensor cable.
3. Check the DVM configuration parameter
values for all internal sensors and/or IF
Box sensors.
