FLASHING AIRBAG LIGHT

[ANDYCAP]

I have just had the headliner renewed in my S type , apparently they took the front passenger seat out to remove the headliner. They did a great job but now the airbag light flashes on start up then stays on. Is there a cable or connection under the seat that needs attention. Any help would be much appreciated.

Hi Andy

My guess is one of two possiblbilites.

1) Seat occupancy sensor not reconnected - Simply reconnect to sort it, or 2) Battery not disconnected before starting the job and a transient voltage event scrambled the SRS module when disconnected /reconnected.. In this case it is probably going to need a re-code for the module, or worst case a new module. First thing  you need to do is to read the DTC codes (or get them read). Failing that, this (from another forum) may help...

"the airbag light should come on for six seconds, then go out and stay out. If there's a fault, the light should come on for six seconds, then go out for two seconds, then flash the appropriate number of flashes for the fault, go off again for two seconds, then repeat the whole sequence five times. Finally the light stays on until the ignition is turned off.
Eg; Flash code 16 would be shown as lamp ON for one occurence of 0.5 seconds, then lamp OFF for one second, followed by six occurences of lamp flashing ON/OFF for 0.5 seconds each (1 - 6).
here is the list of codes i.e. the number of flashes that are seen, may help point you in the right direction

13 - Crash data memory full
16 - Pass seat weight sensor CAN fault
17 - Pass spatial sensor CAN fault
18 - Pass airbag deactivate lamp circuit fault
19 - Airbag circuit status fault - driver
21 - Airbag circuit status fault - pass
22 - Side Airbag circuit fault - driver
23 - Side Airbag circuit fault - pass
33 - Seat Belt Pretension fault - driver
34 - Seat Belt Pretension fault - pass
42 - Impact sensor circuit fault - front
43 - Impact sensor circuit fault - driver side
44 - Impact sensor circuit fault - pass side
51 - Seat belt switch circuit fault - driver
52 - Seat belt switch circuit fault - pass
53 - Airbag audible warning circuit fault
54 - RCM configuration failure"

 

Please let us know how you get on.
