I've had a Renault Espace (III) 2.2 RT-DT 1997 (R) for nearly 2 years now, and I've got a few problems which I'm struggling to get sorted out:

1) The airbag warning light comes on at start-up, followed a few seconds later by 'service', I've had it checked by a non-Renault electronics diagnostic company who couldn't resolve it and said the ECU might need replacing - could this be the only solution?

2) The ABS warning light with the word 'stop' has just started coming on in the last few days, has anybody had this experience, what could it imply and could it be costly?

3) The light behind the dashboard which diplays the radio/cd info is intermittent - I've been told the whole dashboard has to come out to replace a bulb, but as it's intermittent, could it be anything else?

I'd appreciate help from anybody with similar experiences or knowledge of this car!

Many thanks,
Smozz

welcome to the forum. The airbag light is usually the multi connector under the seat coming loose. Disconnect then reconnect and this often does the trick. (pay attention to safety 1st i.e. ignition off or disconnect battery), as for the brake warning 1st off check the fluid level. I think the dash does need to come out for the bulb.

Thanks!

Thanks for all the replies so far!

I think the electrical diagnostics check threw something up around one of the seats, but I'm sure this was an actuating piston of some sort to trigger the airbags, but will check the wiring connector under the seats - probably be this weekend before I get a chance, but thanks anyway!

Will also check the fluid level for the ABS problem when I get a chance - the warning light went off for a couple of journeys yesterday, came back this morning, and is off again this afternoon, so low fluid level would make sense if it's just around the warning level.

Thanks also for the info on accessing the illuminated dashboard display, the images make it a lot easier to understand and hopefully the bulbs are easy to get at as well.

I'll let you know how I get on,
Smozz

I have experienced similar problems with the airbag error. Also the lighting at the back of the speedo display.

With regard to the lighting, my problem is that the wiring circuit printed onto the plastic sheet has a break, causing the lights to work intermittently. I have tried to fix it with some foil, but this failed pretty quickly. I intent to use some paint that conducts electricity (as used on heated rear windscreens) to try again when I have the energy.

It's difficult to get at this bit. You need to carefully remove the grilles over the front speakers. Remove the speakers with a tork key. Them remove the large plastic trim. There are foam pads to hold things in place. These have sticky bits that make first removal tricky. The speedo box is now on display. There are 3 tork screws (small) to remove before you can get at the bulbs etc. It's best to change all bulbs when you get in here as you don't want to have to do it again too quickly. Us a AVO meter to see if you a similar problem to me - set it at 12v and move around to circuit to see where you have voltage. Good luck!

Sorry for not getting back to the forum before now, but have only just had chance to check things out over Easter!

Got to the digital display OK by the method described thanks (very easy!!), there weren't any bulbs out, but played about with contacts on bulbs and connectors to get them to grip better, and initially got them all to work, but after a day or two they started playing up again - they were fine in the morning when the atmostphere was damp, but as it dryed out towards the afternoon - the lights went out again!

I took the front seats out and checked the wiring connectors, but everything seemed OK there, but made sure they had good contacts just in case (although, a previous owner must have already had problems, as the connector had been removed under the passenger seat, and the 2 wires had been soldered back together) - no change on the display though!

Also checked the brake fluid level, and that is also OK.

There is a new development though, and that is the speedo stopped working on Sunday, after returning to the car which was just parked up after a day out - and now not even the damp morning atmostphere makes a difference to the display's bulbs (it was quite hot on Sunday inside the car, don't know if that had anything to do with it)!!

So just to summarise; I have 4 bulbs not illuminating on the dash display, the airbag warning light and 'service' come on after 'OK' on start-up, the ABS red warning light and 'STOP' come on during journeys and the speedo reads '0' all the time - what joy!

I'm starting to wonder whether all the problems could be down to the circuitry/connectors of the digital display itself as the writer of the last post has suggested, or if multiple ECU's are failing, as I can't see that all the mechanical problems that these warning lights indicate could arise at the same time - has anybody repaired or replaced the circuitry on the display before to correct these sort of problems, or has anybody got any other ideas??

I'm going to take the digital display out of the dashboard, to see if I can see any breaks in the printed circuit on the plastic sheet.

I'd like to take the display out completely to do this, but have felt resistance from some of the electrical plug connectors when I looked at it before!

Are there any precautions I should take before disconnecting the display completely and removing it from the car, or reconnecting it?

Cheers,
Smozz

ECU Faults

Hi, Sounds like the ecu is starting to play up.

My espace wont start in the mornings until I warm up the ECU. When it does start the stop sign followed by airbags, service signs flash up before it sorts itself out.

Get your ecu checked out before renault sugest replacing your dash board as this wont work.

Good luck

Hi Smozz,

I would check all the grounding points first, as this can throw up all sorts off errors.


Good luck,
Jat.

Hi Jat,

Managed to get to dash display, and found small break in film circuit - so have repaired and all bulbs illuminating now.

But still have problems with airbag warning at start-up and ABS light on constantly, also the speedo stopped working shortly after ABS problem!

Have started to think about possibilty of a bad earth, but without a manual for the car it's like looking for a needle in a haystack - have you any idea where any of them are (I've found one by the driver's foot well which seems OK)?

Failing that I've thought about going to a Renault Specialist Breakers, and either swapping the digital dash display or the ECU that controls the Speedo, ABS and Airbag - do you think that might sort the problem?

Any help would be appreciated!

Cheers,
Smozz

Easiest way to check if it is a bad earth is to use a jump lead. Clip one end to the negative( make sure!! as positive will damage the ecu) on battery and the other to the casing off the ecu.

Hope it helps,
Jat.

Thanks, I'll give it a try and let you know how I get on!

There's an ECU under the passenger seat as well, can you test this one in the same way?

Yes, you can use the same method to test it. But again make sure you use the negative teminal of the battery or a good ground on the body.


Thanks,
Jat.

The speedo takes it feed from the ABS system,so those two faults are connected.The most common thing is a faulty wheel speed sensor.

Hi,
I've had all these problems over the last 18 months on my T reg 2.2td espace. The speedo had it's own sensor at the top rear of the gearbox, the problem was water getting into the three pin plug and corroding the connections. the airbag fault was in the plug/socket under the drivers (but could be the passangers seat) on the two wires that go to the seatbelt pre-tensioner (I cut the wires out of the harness and soldered them).
The abs fault drove me up the wall first time it was sorted after a et plug on the abs computer/ pump (in front of the nsf wheel) was dried out and cleaned up. but the fault returned twice after and needed two wheel sensors to fix it. knowing which sensor can be a problem, a multimeter from the abs computer plug will give a good idea, but a diagnostic check's the easiest way to find out.
good luck!
Where abouts are you ?
