FG F6 - System Comms Fault whilst driving

Recommended Posts

So I have a system comms fault that comms up whilst I am driving... when this happens the car will usually continue to accelerate even with my foot off the accelerator, or when slowing down and pushing the clutch in the car will start to rev or the revs surge.. If I turn the ignition off and back on the fault resets but generally comes back soon after.. anyone know what this could be? I am thinking maybe a TPS issue... It used to happen once in a blue moon now it happens every time I drive it more than 15 minutes..

Another mine of a thread that has not been looked at for a while. I hope the OP is still around.

@bzerkone, if you get a system comms fault show, did you try and read the codes off the ECU?

I had this problem popup again about 6 months ago. Turned out the ground cable from the battery was disintegrating and turning to dust inside the rubber. Switched it out and added another cable to another ground point and no problem since.

Yep - when my neg terminal was not tight on the battery on my FG F6 - all sorts of lights and wizardary happened on my dash to the point where (well for obvious reasons of lack of current flow) the car would not start.

 

Tightened the neg terminal screws and all good :thumbsup:  

 

At least had a reason for being late to meet the marketing lady when I offered my greased up hand (no time to clean it properly after hunting around the engine bay for the root cause before the meeting with her ...) :roflmbo:
