I was tidying the car and removed some cottonwool wadding that the previous owner had put under the left front seat. The SRS light came on afterwards. I put the wadding back and the light went out but after a few miles it lit again. I removed the front seat securing bolts and tipped the seat back so that I could get at the plugs. I wiggled and waggled the plugs . Cleaned them with switch cleaner but no joy. I then removed the yellow plug and soldered the wires. Still no joy.TOAF gives the following readings.
9134- Side Sensor; communication error
9035- Ignition Circuit IC4 sidebag front seat left resistance low
9132- Side sensor left plausibility error
9036 Ignition circuit IC4 sidebag front seat resistance high
9015 ignition circuit seat pretension left resistance too low
The only plugs I touched were the yellow and blue ones and I replaced the yellow plug with soldered joints. Can there be a polarity issue in the case of the yellow plug soldered connection? but both leads have the same colour coding.
Does the fact that the seat is tilted backwards at about 45 degrees matter? Or does the system require time to reset the codes? Hope some kind person can enlighten me please
