A few weeks ago, we mislaid a glasses case, with its contents. Despite avid searching including in the car, under the seats etc, all to no avail. Then seemingly unconnected, last week the airbag warning light came on. Having taken advice, I disconnected the battery, took each seat out, and there tucked up in the wiring under the passenger seat was the glasses case. So I cleaned all the connectors underneath each seat, but on reassembly, the light still stayed on. So I was dreading an expensive garage job.
Today Ray came to the rescue with a 'MUCAR CS6 OBD2 Scanner 6 System Auto Code Reader with ABS/SRS/ECM/TCM/BCM/TPMS, 7 Reset Services Oil/EPB/SAS/TPMS/ETS/ABS/DPF'.
Which in plain English means it does all the things an OBD2 scanner does with emissions etc, and can reset all those things on that list, SRS being Supplemental Restraint System, which includes airbags and seat belt tensioners.
So I plugged it in, switched on and it came up with the cars VIN and full spec. I went in to SRS, airbags, and it promptly identified the problem: "Firing Circuit, Belt Tensioner (Passenger)"
I then told it to clear the error code, and the warning light went out and has stayed out: it comes on when the ignition is switched on but goes out straight away. So presumably my cleaning the contacts had done its' job, but the error code just needed clearing. Ray is getting a different version reader which will do more on his electric car, so after short negotiations, I have now become the proud possessor of a Mucar SC6, which will get lifetime updates on your wifi with one touch of a button, no laptop or computer required. It will also email you a report direct, in .pdf format.
