When I came home last night I put the key in and no more warning, she started with no problems. So I think, ok fine nothing I can fix if there is no fault so I go to bed. This morning taking my son to school and in the middle of the highway...beep beep beep, IMMOBILIZ failure vdc failure, refused to start. Now, you cant even turn the wheel without power assist running so I left it there on the side of the road.
If this is just a fuse, then the fault should always be present, not just intermittent like this, it's redilulous this refusal to do anything. Then I tried to take off the connector to the throttle body actuator motor but I cant reach it without having to take off the whole intake hose.
Is there no bypass for this, I need to get the car home to at least start and drive home then I can check, surely there must be something to at least start the damn thing.
Something I noticed as well, when I reversed out of the driveway, the rearward sensor that alerts you if something is in the way got stuck and beeped away as well in reverse gear, then, as we were driving along, I noticed something is gonna happen because as soon as I depressed the accelerator pedal just a little bit it cut out as soon as I wanted to accelerate. But it was 100% fine the first couple of km's so there is definately a link to the throttle body and accelerator pedal.
Yes, I get both failure warnings, VDC and then IMMOBILIZ. I know already when I get back to the car later today after work it will start fine - until I am again at an impossible place on the road this is driving me crazy.
If it is the ECU, how to I take it out and maybe blow it out with air or check electrical components, is it under the steering wheel where I plug my cable in or does it sit on top of the plenum? She also used to cut out and give me motor control unit failure warnings once I rev'ed over 6,000 rpm, I always thought it is the limiter cutting in, could be one and the same problem? Where is the ECU located and can it be removed quick quick to open it and check it my dad is pretty clued up about electronics and he might be able to fix it.
I am not sure where the steering sensor is supposed to be located, if I remove the steering cover will I be able to access it and check connections?
Is the ECU part of the body computer unit or are they separate? Can both be taken out and opened up and possibly repaired? I was under the impression the body computer is where I plug my OBD cable in, under the steering column and the ECU sits on top of the plenum with 2x big black cables coming out, that one seems easy to remove.
One last thing I also noticed, once key is turned to MAR, all lights should come on and as the self test progresses they should go out, well, I noticed the yellow engine light, the one that looks like a little compressor, doesn't come on anymore hence why I cant do the emergency manual override procedure.
Thank you so much for everyones help and suggestions this far, you guys are awesome!
