0bdii wiring

[christian1992]

Wanting to wire in a obd2 into my nova just wanted to know what wires are needed to be wired into the plug any help would be great

[Dave.]

Red, Brown, Brown & Blue, Brown & White, Brown & Yellow, Ive got a Powerpoint on my laptop Christian ill show you it tomorrow, says where to wire it upto etc

You can use one of your existing ignition live red wires & a earth brown wire that you have behind the dash to connect up to it, or run a new wire straight to the battery and one to the battery earth. The other 3 wires connect up to there corresponding colours off the engine loom (the Brown & Bluefor ECU light will obviously have to have 2 wires joined into it so you can still run the dash light).

Red - Perm live
Brown - Earth
Brown & Blue - Dash ECU warning light
Brown & White - ECU Diagnostic Link
Brown & Yellow - ECU Diagnostic light

Get a plug from Mallys and we will do it this weekend, i need one in mine too

EDIT: For anyone wondering when engine it is its a X16XE running C16XE Management

[Stuart]

The nova isnt obd2 compatible..... The corsa b is barely obd1

[Dave.]

I think he just wanrs a diagnostic plug Stuart, as it keeps throwing the EML on but he hasnt got a plug wired in to read them off

[Plug]

Just wire the brown/ yellow to a switch, then the otherside connect it to an earth and watch the eml flash

[Benn]

I was gonna say, you can do anyhting on it bar read the fault codes, which you can do by grounding the brown/yellow... Not really worth the hassle.

Dave is right it keeps putting on the eml and annoying me , just wanting to read the. Codes and clear them because when it come on it shuts the engine down

[mowgli]

you only need a paper clip or a small piece of wire in the plug & then turn the ign on & count the flashes & pauses.

or get a gunson reader, its a few bob, but you do get a book of fault codes.

You cant clean xe codes. Touch the brown/yellow to ground, count the flashe the ecu light makes. Go to www.topbuzz.co.uk they list them all, then fix.
