Yet another headache! I’ve done the resistor mod for the battery and all seems okay but if you do a run, stop a short while go to start and the needles go round the clocks twice before I can start it. It also makes the abs light stay on. It’s been off for days but when I had the problem yesterday the abs light came on and stayed on. The battery is still well charged so I’m head scratching, any ideas please?

Anything's possible. Many hundreds done fault free, don't know how you joined wires but one is earth the other +5V. If you used for example chokkie block just unscrew, pull cables, and revert to no MOD @ 12.7v instead of 14V.

 

If it still happens is wheel sensor. Let me know how you get on M8! I can't see any way you could have messed with ABS/IPM cables.

I probably misled you but ever since buying the Voyager it’s done the clock needles spin round twice before starting. I have been getting various jobs done ie radiator, new front suspenders etc, so thought I would do the button mod. Having done it the starting from cold has improved and where the abs light has stayed on before mod, all of a sudden it went out and stayed off. Then the other day I stopped for about 15 mins then going to start it, the needles spun round before starting and the abs light stayed on. It’s not doing anything new it’s just reverted back to what it was doing prior to doing the battery mod! I will borrow an obd11 scanner and see what it comes up with regarding abs light. You can tell the mot is coming up.

Hey folks, just dropping in on my old pals :-)

 

Needle spin constantly, suggests your battery is on it's way out and this is an early warning, most battery testers and meters, etc, don't give you a true indication battery is going, can either live with it waiting for it to die or get a new one, search back though as you need to choose the battery wisely, I believe my old pal @QinetQ posts previously in the forum on the best battery selection, pricey but the CGV's need it.

 

ABS light staying on sounds like you do have an underlying issue there, it could be due to low power confusing the ABS module at each start (Does the starter fire happily and kick the engine quickly/easily each start?).

 

Good luck, and defo needed before MOT as ABS light is a fail.

[QinteQ]

I have a full diagnostic scanner. Even if I properly cleared your codes the error would continue to return IF the BCM module knows it has one of the four ABS wheel sensor's NOT supplying a reading!

 

It's a default catch all code till you find and repair the offending part. Ditto what I describe as 'lifestyle' or lack is use, solution on this is 30 minutes each trip every week to replace CCA use in just one start.

 

Clearly I've no idea what issue you have just ask an indi if they're able to pre-clear the code for the MOT, then get a year test on it.

 

Best of luck.

Watcha Andy lad. You might be gifted my GV about a year from now. Keep trawling the boards after Xmas for message!

Hiya fella, thought I'd say hello and catch up with everyone, will keep in touch and yes I check in now and again if I can help people out. Cheers

Thank you gents I have read your advice regarding battery condition, I should have remembered that I had an XJ8 that would fire up easily and charging was spot on but the asc light and trac light would stay on. I changed the battery all was fine and all the lights stayed off. Just to confuse me I did a 40 mile round trip yesterday with two stops and the abs light stayed on, I basically did the same trip today the abs light went off and stayed off! I’m sure it’s playing with me. I will look back at advice on a new battery but it will have to wait a couple of weeks I’m broke after the front suspenders.

[QinteQ]

It's not "playing with you" just EEPROM programming design.

 

- finds ? Bad so = warning light

- finds ? Good = removes warning light

 

Old school XJ8 would also along with most have charged @ 14+V, Chrysler temperature cell under your battery tells alternator to send 13+V hence my 'lifestyle' warning and batteryMOD.

 

Given co¥id issue you need to do a 30 minute trip once a week summer to keep it topped up my friend. Best of luck.

Hiya Andy!

Hope you and yours are keeping well mate!

@@biscuit remember ABS is a self-resetting warning light, as QinteQ says, when it's good it'll clear the light (after a few minutes of driving normally) and when it's bad it'll light up again. If it's intermittent then you could start looking at the ABS sensors but without diagnostics you'd be shooting in the dark as to which sensor is causing it.

 

@@QinteQ @@bignev all good here fella, thanks for asking hope you're all good. I'm working my way round catching up again, my project Volvo 480 is the main job I have going these days (https://www.youtube.com/playlist?list=PLkG_31Apro1lklGwqRQ0L3Cn5jz067K6R if you want to see an idiot trying to get a car working again!)

You take yourlearning seriously AndyB - some project, and well documented walkthrough ! Many others benefit too.
