Hi all

I bought my carisma over a year ago and it's been a brilliant family car.
It's done 131000 miles, so it's had a few minor grumbles that it didn't object to me fixing, but nothing major.
Just last week though, it lost the speedometer, Back-up light, odometer and cruise control without any apparent reason.

I'm guessing (hoping) it's a wiring fault, but I'm not sure where to start looking. I have wiring diagrams, but still trying to make sense of them.

Hoping someone can suggest a likely cause or a way of testing the harness to find the fault, or if anyone come across this problem themselves.

Thanks

very nice car

what has the recent weather been during this multipule failure

is this a manual or auto

start under the bonnet cluster of fuses and relays

then the interior panel fuses relays if any

check for corrosion in connections

different systems failure

odometer and speedometer are related ..may have a sender at the gearbox

Back-up light ... check for earths and reverse switch .. i thought carisma were a separate white bulb each side for reverse

cruise control ..is this cable set up or electronic

The had been a bit stormy, wet and windy, but not exceptionally wet the day it went (this is Britain). You thinking it finally got into the electronics somewhere?

It's the manual box, with the electronic cruise control on the steering wheel. I did have a look at both of the fuse boxes, I checked all that looked relevant, but couldn't find any dodgy fuses. It does have two reversing light bulbs, unlikely they both blew at the same time.

I forgot to mention that the SRS light came on at the same time the other bits stopped working.

There's a lot of cables, trunking and pipes making a physical examination of the wires a problem. What path do these circuits take through the engine bay that could cause or expose them to damage? Or is it just a task of pulling connectors apart and checking continuity?

I'll test it that way if that's the way to do it, I'm just a bit cautious of false positives if I'm not doing it right, could waste a lot of time...

I pulled the VSS from the box to inspect it, looked ok, but in all honesty I don't know what it should look like, can't find a photo anywhere.

Check the battery voltage - maybe your alternator isnīt producing enough volts.
Electronics tend to need a minimum voltage.
Fuses may look good - better check them with multimeter for no resistance.

If thatīs all good I would start at gearbox - speedo - reverse light - cruise control - could all be at gearbox.
Might just be a loose ground ...

definately sounds like a wiring issue or corrosion or a faulty vss for sure.... my 3000 gt vr4 has a bad vss..... i have no cruise control or speedo or odometer.... keep in mind that the computer needs to know vehicle speed to activate cruise.... so in other words... no working speedo will cause the cruise to not work

First of all: Thanks for all the help!

Finally had a chance to have a good look under the bonnet, removed the air intake hoses and filter-box to get to the gearbox, and started testing from there.

Found what I think was the wire that supplies power to the VSS and Back-up switch had been rubbing on the edge of a metal support. Just got through the insulation, wasn't touching all the time, but with the wet and probably the position I'd parked the car in, it shorted out and blew the fuse in the passenger compartment.

So a bit of rubber tape and a new fuse later, put everything back, turned it on and everything is working!
Even the SRS fault has gone.

Thanks again

Hi everyone.

Hoping to start this up again because after the repair I made I've had weeks of problem free driving, but then, after weeks of dry weather, it blew the fuse again.

Replaced the fuse.

I week goes by and then it blows again.

Then over the weekend we're on a weekend away and it blows 3 more times.

While blowing fuses, learned that it only blows when I turn the ignition to start too quickly.

If I turn it and wait for the same time it takes for the glow plug light to go out (even if the engine is warm) it doesn't blow.

I have a theory involving the VSS, it's the only common component downstream of that fuse that is also connected to the glow system.

What do you think? And if it is the problem, does anyone have a mitsy or volvo part no.?

Big ta.

Could also be resistance glow plugs is decreaseing.
Less resistance means more amps + the amps from starter and you blow fuse.
Check resistance glow plugs - maybe better to change all four - they do get old.
Better start next winter ...
