I bought my 97 P38 4.6 HSE back in January with the SRS light on hoping it would be an easy fix. After a few months I was took the car into an independent garage and had their Autologic to find the fault, it appears to be the rotary coupler according to him and he quoted me £140 for the pleasure for replacing the coupler.
As I was already spending £250 on getting the heater matrix o rings replaced, I thought I would attempt to replace the rotary coupler myself with a £18 second hand one from a breaker. I have the RAVE and I think I understand the process but have a few questions about it that I am sure someone on here can clarify.
1. When disconnecting the battery, do I need to follow the 17 second ignition key procedure to stop the alarm going off? I haven't been able to find information about the 'back up battery' noted in the workshop manaual from 96 models onwards and if it is fitted to my car.
2. How can I move the steering wheel to get to the 4 torx screws without moving the wheels? Am I misunderstanding the instructions?
3. Once put back together, will I need to take it to the independent garage to get the fault code cleared? Only reason I need this done is to get it through an early MOT.
First time I have needed to do this to car so wanted to have some extra information before disconnecting the steering wheel and taking apart the steering wheel.
