All,
For some time I have had a warning light that goes out after about two minutes and I need to fix it.
I have an OBD2 s/w pack and interface cable that I bought a few years ago an have never used (cheap from ebay, which I bought for a 51 clio I had), but I noticed the connector is the same type as the 993.
As my MY is 1994 and the connector cover says OBD not OBD2, I am assuming if it works the info I get will probably be limited. I am hoping it will tell me which airbag is reporting a fault. Failing this I am guessing I will have to disconnect the battery, wait a bit and access the orange conector to disconect the steering bag an insert a 2.8 ohm resistor in its place to see if it is that one that is keeping the light on for two minutes. Then move to the passenger unit if there is no change.
Is this the best DIY approach or are there other techniques I could consider. I have an MOT coming up so want to know where the fault is rather than replacing both bags.
Some other threads also suggest the cause could be dry solder joints on the clock PCB? Anyone got any details about this?
I am handy with a soldering iron if that s the route I need to take.
Any help gratefully received.
p.s I have tried the old ignition on with foot on throttle method, but no flashing lights that relate to airbag faults.
