05 Monaro VXR indicator constant

[preciousmetal]

05 Monaro VXR - all 3 indicator lamps on NS are on constant orange inc green dash indicator. RH indicator works and hazards work on OS. tried obvious fuse for indicators. cant find an indicator relay to check. pulled out lighting main fuse under bonnet to stop them flattening battery

any ideas please, weird one

Dear pm,

have you reinserted the fuse?
Is the fault still there?

Is there a dedicated flasher box or are the indicators controlled by one of the ECUs?
If one of the ECUs does the indicators then pulling the fuse and replacing it may cure. If not I'm thinking the output for that side has gone short circuit.

There's a few members who've got schematics for the car. Hopefully one of them'll be along to assist,

regards,
Jet

Thanks tried reinserting lighting main fuse, inds. still on permanently, have swopped lighting fuse with another, still on. will try the ECU fuses if in handbook thankyou

I think there is a common fault that is to do with relays in the body control module . If you google vz indicators bcm you should find some info.

That looks plausible. Indicators controlled by BCM. Relay sticks. Lights stay on. Replace relay or BCM to fix,

Have recently had this with another GM car, identical symptoms,( you could hear the relay trying to operate when the engine was off ) £20 saw a new relay and the problem solved, I should point out that no errors were logged on diagnostics . The flasher relay should be in cabin above the fuses, top left , three pin

Sucking eggs I know but if you do a swap with another monaro relay then its a quick easy check, if it still doesn't work then the relay wont be the problem

thanks, swopped cabin relay for lights / lamps - no change - NS indicators still on permanently, but remove hazard fuse in same box and hazards don't work but indicators now work normally both sides, even more confused now ...........

My first thought was that you had a faulty circuit, that was grounding to earth through the indicator circuit - and it would have to be something that wasn't on a switched live.

Now that you have mentioned the above, as the hazards are on a permanent live feed, I would say it's got to be that circuit, and either a faulty hazard switch or relay (if it has a dedicated circuit). My money is on the switch.

thanks, looks like its a common fault, but never had it before and that's having had over 100 Monaros

look like hazard relay fault inside bcm, desolder and replace relay......... simples ............not

Is it not worth trying another switch first then?

do you mean hazard warning switch ian ? if so make s more sense to try first

Yes. If you can easily swap for one from another car, and see if the fault transfers too.

Different car admittedly, but recently had this on another car, it turned out to be the hazard lights switch/relay.

[MatrixXXx]

It has to be the Hazard relay, the switch if stuck would just keep the relay flashing.

you could just bypass the BCM and wire a flasher relay into the indicator circuits controlled by the switch, with a couple of diodes to stop cross feeding, the only thing you would lose would be control from the BCM like the alarm etc?

Give Roger at MF a call, had an issue with mine staying on, he fixed it last week
