Right folks.
Attacking this again.
So far we have changed the clock spring.
Checked the fuses, checked the three wires from the fusebox. Yellow to diagnostic plug, purple from airbag module under rear seat. Purple also goes to the dreaded srs dash bulb light. Green is the power from fusebox mounted on drivers inner wing. Fuse humber b5-2 red 10 amp.
The other end of the purple wire goes to the bulb then back to the fuse A4-2...
Checked the pre ignitors all 2.7ohms.
So my thought process is..
The power comes from the fusebox. Along green wire into airbag loom to the module. Then powers that. The purple wire comes from module back to the dreaded srs light on dash.
What else could I do.
Check the clock spring connection again and the resistencein the steering wheel airbag.
The airbag module has as far as I know never been set off.. how sensitive are these? WHO REMANUFACTURES THESE.
When rover suggested the airbags be serviced every 10 years(back in the day) what did that involve?
Also checked the srs bulb is a 2.2 Watt bulb and not a more available 5 watt bulb.
Does the module need a full 12v to function properly. My fusebox was giving me some strange readings. Blamed the voltmeter to start with....
Also found a bad battery -ve terminal on the carso that will get dealt with..
Been over all the simple things but drawing a blank.. someone must have been in this same position with the dreaded srs lamp.
Historically the car had the main airbag loom power plug cut off due to what was advised as low resistance in wire... (not exactly 100% sure what that meant on mot mans report)..
Any help appreciated... Internet seams to be lacking in ideas for me... (other than bulb out or tape over it)
This has been useful for wiring diagram.
