"Error 2"

[FJR1300]

Most vehicle electrical problems start out with a bad ground, looks mean nothing. Best way to test your ground is via voltage drop, measure from a known good ground, use the battery terminal for convenience, the other lead at the ground point you are considering.
Max reading is .5 volts, but even that is bit a high in modern cars, I recommend < = .2 volts.

If you have that, the next thing to check is whether that voltage reading changes with temperature, if you have a multimeter with record fumction, you can just leave it hooked up and run the engine for a while,, then let it cool back down and check your max readings.

One common area that causes high voltage grounds on the entire vehicle is the negative cable where it connects to the engine block, particularly in snowbelt vehicles.

If your multimeter has an ammeter function you can take recorded readings of that also (as long as you're tapped into a power source rated <= the ammeter capability)

This is all above my head to be honest. I have tried two ground locations and changed out fuse tapes etc. My radar detectors and the Laser Interceptor that I had all run perfectly in my car, so I am not sure what the deal is. AL is looking into it. We will see what they come up with. Whatever it is , it's something in the ALP that is not agreeing with my car obviously.
