Problem with reverse lights

[InFlames]

Hi everyone,

I have a problem I need help with. My reverse lights stay on no matter what I do (short of turning the engine off). It stays on with or without headlights on, gear in neutral. Anyone knows how to troubleshoot?

Thanks...

Where and what is M & Q? I'd troubleshoot it myself if someone could just point me in the right direction. I looked in the fuse box and none of the fuses look blown.

Electronics get me everytime!

M&Q is @ tampines. they are repairing bimmers since the days they started in this industry. look for Mr Chia. Very delicated in servicing.

They entertain drive-ins? I know some workshops are always booked and they don't like to do troubleshooting because it takes time and cannot charge alot for it. Plus I can only go on Saturdays

Re: Problem with reverse lights

its the wiring at your rear lights that gone nuts, not the fuses bro.
pop open your rear lights cover and see if anything wrong with the wiring.

Re: Problem with reverse lights

bro, i also highly believe is the wirings at the rear light.

this are the steps tat i will do ba... i'm no professional, but no harm trying...

1) open up the tail light cover , i'd start off from the driver's side.

2) check for any wirings that is exposed... it might be that the wire for the reverse light is exposed and pressed against another live wire?

if still cannot

3) trace out which wire is connected to the reverse bulb... trace that wire to the harness...

4) unplug the harness and take a tester (12v tester) to test if the wire that was supposed to be connected to the reverse light (linked to your car, not to the tail-light) has got electricity running or not...

IF HAVE = siao liao.. i also dunno what to do liao... it may be the line is explosed and pressed against another live wire along the way...if this is the case... i'd recommend u get a workshop to check...

If Don't have = your tail light internal wirings got problem ....

hope this helps..

Ok, I will try this and update you guys.

Does it matter that BOTH reverse lights are on? Which means both reverse lights just happened to short themselves, or is there a central circuit that was shorted?

bro, that's why i ask you to check the driver's side

What i realised was that the wires is actually peddled from the driver side to the passenger side.. from the harness, you can actually see some wires from the harness that goes to the passenger side ... so if 1 side kena short circuit, the other side should light up too ...

Re: Problem with reverse lights

Ok folks, source of the problem has been identified - it was the reverse sensor switch. If you jack the car up and lie underneath it it will be on the left, if you're looking directly at the gearbox it will be on the right of the gearbox. It's a small little clip. Easy fix, wiring was all fine.

I was told if both reverse lights are on then its the switch. If wires cross all your lights will be screwed up, depending on which are the wires affected.

One more for the record.

Forgot to add, this fix is for manual gearboxes only
