Install the two ultrasonic sensors on the “A” pillars (see pic below). One either side of the
windscreen pointing towards a hypothetical point at the centre of the rear window and
ensure that between the ultrasonics and the rear window there are no objects (i.e. headrest).
Plug the ultrasonics connectors in the module paying attention to their colours: RED and
WHITE. Do not cut or lengthen the ultrasonics cables. Plug the 4 pin BLACK loom connector
in the module. The module can be placed under the dashboard on the driver’s side.
Sensitivity increases if you turn the adjuster clockwise and decreases if you turn the
screw anticlockwise. NOTE:
This operation is important as
you do not want to have false
alarms. To check that it is not
oversensitive,arm the alarm
and hit the front and rear
windows with your hand (care
should be taken not do
damage the windows).The
system should not generate
any beep and flashes of the
LED on the receptacle.
