Connecting power rear ECU
• The rear ECU gets power from the reverse light circuit of the vehicle. Use the red/black rear ECU
power cable with the 2-pin connector and the included cable clips to make the connections.
• Locate the +12V power cable of the reverse light circuit and guide it through a cable clip.
• Insert the red cable of the rear ECU power cable in that cable clip and press the metal part of the
clip tightly. Close the cable clip.
• Locate the GND cable of the reverse light circuit and guide it through a cable clip.
• Insert the black cable of the rear ECU power cable in that cable clip and press the metal part of
the clip tightly. Close the cable clip.
• Connect the power cable to the rear ECU.
Connecting power front ECU
• The front ECU gets power from the ACC power. A signal from the brake light circuit will activate
the system. Use the included orange/brown/black front ECU power cable with the 4-pin
connector and the included cable clips to make the connections.
• The front ECU power cable contains an On/Off switch (F), which enables the user to switch the
system off (e.g. during traffic jam).
• Install the On/Off switch (F) in an easy accessible location on the dashboard. The included hole
saw can be used to drill the hole. Be careful not to damage any cabling or other vital parts of the
car when drilling.
• Locate the +12V power cable of the brake light circuit and guide it through a cable clip.
• Insert the (brown) cable marked with ‘B’ in that cable clip and press the metal part of the clip
tightly. Close the cable clip.
• Locate an ACC cable (e.g. from car radio) and guide it through a cable clip.
• Insert the (orange) cable marked with ‘ACC’ in that cable clip and press the metal part of the clip
tightly. Close the cable clip.
• Locate the GND cable of the brake light circuit and guide it through a cable clip.
• Insert the black cable of the front ECU power cable in that cable clip and press the metal part of
the clip tightly. Close the cable clip.
• Connect the power cable to the front ECU.
7. Operation
Display overview
Start-up
• Make sure the power On/Off switch (F) is in the on position.
• When reverse gear is engaged, the system will beep once (0.5 seconds) to indicate diagnostics
mode started. Both rear and front sensors start working.
• When a failure is detected, the display will show the letter ‘E’ followed by the ID of the faulty
sensor(s) for about 3 seconds. E.g. when sensor number 3 is defective, the display will show
‘E3’. After 3 seconds, the faulty sensor is still indicated as its display indicator is not longer
shown on the display (see example below).
• After 3 seconds, the system enters warning mode and will continue working but obstacles
behind the faulty sensor(s) may not be detected.
• When none of the sensors are working, the message ‘EE’ will be displayed, and the system will
beep continuously for 1.5 seconds.
