Case 2: CAN-box does not detect reverse gear
If the CAN-bus interface does not d12V on the green wire of the 6pin to 8pin cable
when reverse gear is engaged (not all vehicles are compatible) an external switching signal
from the reverse gear light is required. As the reverse gear light signal contains electronic
interference, a normally open relay (e.g AC-RW-1230 with wiring AC-RS5) or filter (e.g. AC-
PNF-RVC) is required. Below schema shows the use of a relay (normally open).
Connect the green wire of the 6pin to 8pin cable to the output connector (87) of the
relay.
Connect the Reverse light’s power-cable to coil (85) and the vehicle’s ground to coil
(86) of the relay.
Connect the output connector (87) of the relay to the rear-view camera’s power-
cable, like you did it to the green wire of the 6pin to 8pin cable before.
Connect stabile and per12V to the relay’s input connector (30).
