Sensor testing
Turn on the ignition so the car is under power (differs by the
model and the age of your car).
DO NOT start the engine.
Make your handbrake on. Then shift the gear to reverse.
Place the display for testing in the trunk.
ONLY plug in sensor A cable into the Control Box slot A.
Stand in
~2m
distance from
sensor A
(the sensor should NOT
beep and the display should show two minus
signs “– –“ in RED).
Then move slowly towards your car. In
~1.5m
distance from your
car, the beeping sound starts and the display should show the
corresponding distance as you move closer and closer. You can do
it by yourself, but it is easier to ask a friend or family member to
help you.
Unplug sensor A
If the display is not powered on and showing either two minus signs
“– –“ in RED on the display then, check your wiring with the reverse
light again. If the display is neither beeping nor showing the
distance when you went closer to sensor A then plug sensor A for
testing in the slot of one of the other three sensors.
Unplug sensor A and try connecting sensor B
If everything is working continue with the other sensors.
ONLY plug in sensor B cable into the Control Box slot B.
Stand 2m away from the sensor B and move slowly towards it. The
display should show the corresponding distance as you move
closer and closer to it.
