'95 S320 SRS light goes on every time I start the car and goes out every time after a minute or two. I have an actron cp9135 OBDII reader and the only code it shows is P1137 which i think is rear O2 sensor. Per a forum I purchased some contact cleaner and lube from Radio Shack and did each buckle, no change. Any ideas and any ideas why my reader is not giving me any other codes? Thanks, Steve

Because SRS is not an OBD system.
