SRS lite can be a number of thing....most common : Batt+ power failure. Then....Short to ground. Clock spring ( cassette.) causing an open. Poor/bad ground. Fault in SRS sensor/s.
You'll need OBDII port or underhood adaptor/scanner to read them or one of the generic scanners.........Please don't go to AutoZone for a 'free' code reading.
Have had a few cars with ECU problems ( One with bent OBD port pins. ) after a visit there.
I think our local MB dealer charges $100.00 per, and I'm told, they then won't tell you the codes.
