My car is a 2002 XJR and I’m planning to work on the Clock Spring for which I need to remove the driver’s airbag.
All the airbag removal instructions that I’ve read tell you to disconnect the battery for several minutes or up to an hour before doing work on airbags. Well, I’m looking at the electrical diagram 18-1 of the Jaguar 2001-2002 Electrical Guide that shows the car’s various airbags connected to the Airbag Single Point Sensor Module. The diagram shows only two leads coming out of each airbag and going to the single point sensor module and those two wires are the only airbag connection to anywhere in the car. Furthermore, the only power source shown on this diagram shows it coming from the ignition switch to the single point sensor module; no other power source. There is no battery connection shown on this airbags diagram. If this is correct, what’s, then, the deal with disconnecting the battery to work on a device that shows no use of battery power?
Would anybody know of another possible power source to the airbags, or any other connections that this guide is not showing?
