MGTF SRS Light ON!

I know this is a common problem, and I have checked and tested the underseat connectors, for which I get a 2.6 - 2.8 ohms each plug, so the pre-tensioners appear to be OK. (Correct assumption?)

Have replace underseat connectors with soldered spade connectors. No change light still on. Checked cable from pretensioner to underseat connector. OK

pscan indicates:

1526 pretensoner circuit right ignition switch fault
1524 pretensioner circuit right high resistance


So, I think the only thing it can now be is the rotary coupler behind the steering wheel, or the SRS/Airbacg ECU!

Is there a way of testing this? are there any other possible faults? That may contribute to the problem?

Any advice would be appreciated, as this is now driving me wild!

PS: The Horn works, and fuse checked.

if you have 2 airbags check the other side they are in parallel.

The Rotary Coupler has a fragile SRS connector in it-may have fell apart.

I also believe that a low battery can cause this problem.

Hi Only single airbag. No problem with battery full charged.

Hi ok,
have attached some info about the rotary coupler.
The yellow cable is the SRS plug
