V36 350GT - Air-con , radio not working

[Pac]

Hello Guys 

I have had a issue with my V36 350gt Sedan radio screen has switched off and now i don't have the radio working and can't change the air-con .

The Car runs fine but no way of using the entertainment unit which is also connected to the aircon .

First i thought maybe the screen/monitor or the switches or the radio control box . i brought all three and replaced them and still no success .

The next step was i have taken it to my mechanic but he specializes  in European cars so all he could do for me was to advise me of the error code. 

BCM - DTC B2611 - ACC RELAY 

I'm hoping one of you might be able to help find this relay and advise on how to replace it.

 

Cheers Pac.

Extracts of the G35 workshop manual, which might be a good starting point.

Thanks Mate , that looks like a great place to start.

Worth checking every fuse in the cabin and engine bay.

The error code clearly says that the Accessories relay is not working.  So either the relay, the fuse or the wiring in that circuit are compromised.

[Pac]

Checked the fuse in the cabin and engine bay not sign of the Acc Relay , its going to be somewhere inside , but it is hard to find.

[Pac]

Thanks for the help guys , i'll pass on the details when i get it checked out but it would be good know if anyone does know exactly where i can find this ACC relay. the G35 stuff kind of shows where it but i think it doesn't match the Japanese models.

Its been a while since i have been on SAU  and one thing that still strong with the group and helping each other out.

Have you checked near your accelerator pedal as the diagram indicates?

[Pac]

Had a look at that , there is a fuse box there so i'll look at it in more detail today  , but being that the infinity have the steering wheel on the other side i'm guessing it would be on the passenger side of the car.

[The Max]

Not necessarily. Wiring harnesses typically come in LHD and RHD flavours, so it's still very likely that those relays and fuses will be on the driver's side in your vehicle, as they are in mine when compared against the US G37 workshop manual.

[GTSBoy]

In Nissans, almost all relays are either in the engine bay fusebox, or strapped near the ECU.

[Pac]

Finally !! I found the Relay , right where you guys said it was but it wasn't in plain sight , the relays are attached to the back of the fuse unit .

Just in case someone else has this issue here a picture , now the next step to to find a replacement relay and lets hope that fixes it if not then its gonna be some work replacing the cable.

Thank you all for the help.

Swap it with one of the ones next to it and see if the problem moves with the relay.

Those sneaky Nissan guys

Just swap a relay to see if it's fixed first

[The Max]

Exactly what Ben suggested. Swap with another one that's known to be working and see if it kicks in. Just don't pick a relay that disables anything else that the AV+A/C system would rely on, in accordance with the workshop manual.

If you know someone with access to a multimeter, just check the relay coil to be sure it's still in good working order (compared to another relay) and if it passes the resistance test, then feed the relay coil with a 12V power supply and check continuity between the contactors, as indicated on the diagram that's engraved into the relay. That way, you won't be wasting money on an expensive Nissan relay.

[Pac]

Great success! well not great but good , the radio, Bluetooth and screen have powered up but still nothing from front panel aircon and controls , but the steering wheel controls are working .

Maybe because the relay you swapped it with was for the A/C?

At any rate, definitely a dud relay. Replace that and hopefully that'll be all you need to do.

[Pac]

Great News ! i got the aircon controls up now , i brought a spare air con control unit cover just in case if that unit was faulty just replaced it and everything is back online.

Thanks to all you  SAU members for the help .

[Ben C34]

Sweet. Please post a skid vid to show appreciation.

 

 

[Pac]

Worth a thought , but i'm too old to be doing that , back in my r34 days yeah but in the v36 i'm not sure if it suits it.
