Hi. Lonster,
I think this has something to do when a coolant temperature sensor gives of a.35volts or less for any length of time ( when the water temperature sensor is normal) All dash lights flashing most upsetting I found when it happened to me. Basically I think I'd switched the ignition on when I had the gas pressure sensor disconnected but i think this might happen if any of the engine sensors are disconnected when the ignition is switched on , I had a laptop with me and I was able to cancel the fault codes and stop the flashing dash lights, If you havent got ap top with the required soft ware, I think you can rectifye and cancel the codes by switching the ignition on and dancing on the accelerator pedal in a strictly timed sequence. witch I cant remember how to do or describe. If you go to the mechanical discussions you may pick up on it descibe in one of the Cat Postings as it has been describe quite a few times before.

Regards Titus
