Hello guys, I have an Jaguar xf 2.7, 2009 model.

the airbag light is on, at first it turned on and off but after some time it stayed on, i got a scan reading from a workshop and it says something is wrong with the crank position on the rear left. We tried to clear the code but the srs light stayes on, how do i turn it off, any suggestions?

 

I’ve had to replace the clockspring in the steering wheel on my XK for the SRS light others have had problems with the drivers seat airbag connection

 

Are you anywhere in north Virginia? I could come over and do a hopefully better reading and clear it again if you’d like.

 

thank you very much but I live out in Sweden!

Update: the light turned off without doing anything but I’ll keep an eye out

 

This could be as simple as a partially discharged battery failing to provide sufficient power for normal monitoring of the restraint system. If you are not so lucky and the warning returns, an explanation of how it operates may help:

When the ignition is switched ON the RCM (Restraints Control Module) supplies power to the impact sensors which perform a self test.

1. after satisfactory self tests the impact sensors continually output 'digital acceleration' messages to the RCM.

2. if a fault is detected the relevant impact sensor sends a fault message, instead of the 'digital acceleration' message, to the RCM which stores a related fault code and illuminates the air bag warning indicator.

There is a seven page list of relevant fault codes in the Workshop Manual which can be retrieved by Jaguar SDD (Symptom Driven Diagnostics) diagnostic system from the RCM via the high speed CAN bus connection. As you can imagine from this, guessing possible causes is not the best approach to troubleshooting restraints faults.

I can relate to this explication because the previous owner talked about changing the battery to a new one, on the dashboard when the car is on stall it also says limited performance but I haven’t had any issues to be honest, but better to be safe than sorry. Do you suggest that I change the battery once again?

 

Most of us get four to five years out of a battery on a 'modern' Jaguar and weird electrical issues are a classic indication one is beginning to fail. You could get a 'drop test' done on the battery as a health check.
