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 compa
ti
ble) 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
fil
ter (e.g. AC-
PNF-RVC) is required. Below schema shows the use of a relay (normally open).
Cut the green cable of the 6pin to 8pin cable close to the black 8pin connector.
Isolate the short end of the green wire (CAN-box side).
Connect reverse gear light signal/power to coil (85) and ground to coil (86) of relais.
Connect rear-view camera power and green wire (video-interface side) of 6pin to
8pin cable to output (87) of relay.
Connect permanent ba
tt
ery power to input (30) of relay.
