Hi Jim,

It's indeed related to the left-sensor. BTW it can be easily diagnosed without the SRS tester by comparing the electrical resistance (Ohm) between the two sensors. There are 3 pins per sensor, the outer ones are having the same resistance, the middle one is "0".

If one the two is different, you've got one of the two failing. However my technical english is not good enough to exactly explain how to measure this with a voltage meter.

I had my FS1 (left sensor) replaced and the SRS unit did not need a reset, the SRS light switched off after the selftest.

Hope this posting helps others to resolve SRS lights. It's much easier to diagnose then the airbag steeringwheel ring. Please do follow the usual safety precautions by disconnecting the battery for at least 30 minutes.

Regards,

Robert/NL

At SRS school, we were instructed to never use an ohmmeter on the SRS system; the small voltage applied by the meter's battery could trigger the Airbag. Also avoid using a Voltmeter on a live system.
It couldn't hurt on a disconnected G-Force Sensor, but neither could it detect an intermittent fault.
Without a thorough knowledge of the whole system, avoid poking around at the wiring with a meter. You'll need the SRS tester to reset it anyway.

in my case I had the sensors disconnected so the voltage meter couldn't trigger the airbag. ofcourse taking all safety precautions first.
