Hawkeye fault code 4022?

Hello again everyone

On my way home tonight all my dash lights, (except oil engine power) I pugged it into hawkeye and error code 4022 - referance earth not conected to earth- I've searched the web for the code as well as on here, and other site but can not find the code, or the referance earth thing as anyone got any ideas what it is, I have already checked the earths and their ok, if you turn the engine off and on again it goes off for a bit but the lights came back on again, my disco still runs fine even thought the lights are on and I have also checked the wheels just in case they were lose, but they wasn't......

Also while I was checking it I heard the sls relay energising even thought the key isn't in it, but that's been doing that For a while to be honest

Any help, as always would be greatly appreciated

There is an earth header beneath the footwell on RH side, under the pedals which has connection with diagnostic socket too, this used to make tricks...check this header / give it a contact spray or something(C0551)... albeit i have no idea what that fault code means

Hi sirrafery

Are you referring to the in the engine bay under the window?

No, this one, lift the carpet

Thanks will have a look tomorrow, now in bed and the misses might not see it my way

By the way, how old is your battery?

Ive got the same 4022 today!?! Haven done anything yet but will crack on tommorow morning checking and cleaning earth points. My battery is less than 1 year old. Solly... The thread I started is call "I havent got the 3 amigos but its bad." hopefuly we can get sorted

On on the same thing in the morning, my battery is 2 year old but it as just been conditioned so I know it's ok, I hope it's something simple, I have have a bit of bad look resently with mine, trouble is I still like her ( the disco that is, her name is andie)

Will report tomorrow :doh:

Just pulled these screen shots from rave. Might make things go a bit more smoothly??? Is C0017 behind the door mirror or on the passenger side floor though?

U found C0017 well cos this one is also connected to the diagnostic socket.... but it could be any earth point in the front of the car.

Check c0551 today, also for good measure I clean the plugs on the abs pump, cleared the fault and so far it's not come back, so looks like it may have been the earth plug, not done many miles yet so will know more next week if it comes back on, but so far so good

Thanks again all

Solly great news! I didnt check the earth point under the brake pedal but I unpluged and checked the ohms on both front sensors which were fine so I pluged them back in then when I checked the abs block the round plug with the single wire was loose so a quick push and a click and I thought I'd try my luck. Switched on with no lights selected reverse and as soon as I touched the accelerator the abs unit did its pulsing as if the abs was activated under heavy braking and all lights came back on Switched to live data and both rear sensors read 2.23v and 0Kph front right 2.23v and 0Kph front left reads 0.00v no now its 0.57v hang on now its 0.8v and then 0.00v again... Ah harrr we have a culprit especialy as hawkeye reports the front left wheel is doing 5Kph when stationary Im just wondering if I should do just the sensor £46.20 with vat or chuck a new hub on £198 with vat both are Wabaco parts at that price. Just changing the sensor aint suposed to last that long and that would be a waste of £46... Hmmmmmm decisions decisions.

Bugger, didn't check that I've already had 2 hubs done, hopefully mines ok, but ill check my out tomorrow, bummer about yours though, I would probably take a chance and go down the cheaper option, as it cost me over £300 to have one done, but at least you know it will be ok if you have the hub done. You have to let me know what you decide

see this too, there is an explanation at the end http://www.landyzone.co.uk/lz/f8/i-...s-but-its-still-bad-166818-2.html#post1668538
