Buttload of warning lights but nothing is actually malfunctioning - ZPC??

[Eicca]

Posting in behalf of my uncle. He just got a 2008 GX470 in pristine condition with 80k miles on it. He replaced the shocks, springs and tires for a 2" lift and eliminated the electrically-controlled shocks.

He did not do a zero-point calibration on it after the suspension work.

Two weeks later and he's got all the warning lights, a P0500 code, and the dealer is saying his ECU is bad. But nothing is actually malfunctioning. Everything still works, other than the VSC/ABS now being disabled by the computer.

He replaced all the speed sensors on the wheels and transmission but no change.

Is this as simple as a zero-point calibration problem?

He's going to try and get it back from the dealer so I can poke around in it.

Thanks for any input.

CORRECTION: He replaced the front shocks with something that raised the nose by 2" and adjusted the height sensor to raise the rear. Stock air springs and height control are still installed.

P0500 is generic fault for speed sensor.
You would need more specific software that can read ABS fault.
Try techstream of you have access to a computer. And buy the recommended OBD VCI adapter.

Since he just replace the suspension, it's very common to stretch the ABS speed sensor cable and damage it. If he replace the sensor it would not get fixed if the cable still bad.

I'll try and get my Techstream on it. He took it to the dealer before I talked to him and apparently the dealer is saying it's the ECU, they can't figure anything out, the head mechanic won't be back until Wednesday, etc etc etc.
