Hey R34 Owners,

I've had my R34 for 8 days now but there's a switch in the car that I have no idea what it does. It's just above my right knee and has 4 settings ( 0, 1 , 2 , 3 ) with a icon of a head light.

I've read thru my manual but it doesnt seem to shed any light on the mystery switch. Any help would be appreciated!

yes it's the headlight angle adjustment.

park your car in front of a wall at night with your lights on and switch the dial 1 through 4 and see what it does

have fun

see thats what I initially thought it was but it doesnt seem to change at all, I've even had a passenger stand outside and look for me. Perhaps it may have been disconnected during compliance???

not understanding what is hard to believe.

if the switch is connected then why wouldnt it work..

i changed mine back to xenon.. set the switch to lowest position to not blind anyone (not like its that harsh anyways) and off i went.. into the sunset

Maybe the fuse is out or blown...

Sure it is something stupid like that :P

my car has switch taken off and xenon replaced with halogen lights.....anyone know why they do this just stuffs up a nice feature the car had from factory.......

To comply with ADRs, which state that any car with xenon (HID) headlamps must have automatic headlight range control (the switch on the R34s in manual adjustment) and headlamp washers, which the R34 doesn't have.

You'll notice on the European cars (and now some domestics too like Holden Caprice) when you order the Xenons as an option, it usually comes as a package with washer jets and automatic height adjustment.

    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
    • No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.
    • Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
    • You think its the AFM? I know its a common issues on R32s. I find it coincidental how this issue raised right after cleaning the fuel system. As everything except the fuel system was fine before. I tried running it with the IACV unplugged but did not notice a difference and still stalled. However, the RPM gauge is not in the cluster right now, so I will need to connect the laptop again and use Nistune to check the RPM. I will check this weekend.
