Brody Walker Posted November 23, 2013 Report Share Posted November 23, 2013 Hi guys & girls. I have fitted a G4 plug n play to my r34gtt skyline. Whilst calibration I noticed that when I turn the key off the dash lights & gauges remain on, the radio however turns off. The only way to turn it off is to disconnect the battery. Power is still going to the ecu too.   have a auto watch security system installed if that's any help. Has  anyone ever had this issue before or know what it could be?  Quote Link to comment Share on other sites More sharing options...
Simon Posted November 28, 2013 Report Share Posted November 28, 2013 It could be a back feed causing the ECU to remain powered and in turn keep the main relay on. Pin 31 should get a switched 12V from the key this hen causes the ECU to supply a ground to pin 4. If Pin 31 does not loose its 12 volts when the key is turned off the ECU and main relay will stay on. Pin 4 should go to 12V when the key is turned off.
