Re: tips on checking airbag system
well i did unplug the connector from the trw unit (without disconnecting the car battery, was worried about losing key codes etc), has i see it surely the unit must need a fair wack before it sends signals for airbag deployment.
lucky my thinking worked, no big bang & still in one piece !
i left it over night, had a quick look at the pretensioner wire connections, all look ok, i have not had time yet to check for continuity between connector blocks but i doubt that theres a break.
still really worried about using a meter on those pretensioners, don't like the way that they are so tight up against the carpet no wonder the seats are hard to slide back, were they an after thought by alfa ?
of course even with the airbag ecu disconnected the bloody warning light is still on, suppose it's still got to warn you of total failure.
i did reconnect it for a few minutes, but of course the warning light is still on !
i really would like to know how the dealers machine does reset it, the connector only has 3 wires in it, does it just earth one or send a voltage to one or a complete a circuit ?
maybe i'm wrong, but how much can you do with 3 wires..............oh i know, charge a fortune for an hours labour charge !
