Ok, I'm not sure if I should start a new thread, so I'll just ask here first.

My particular 2001 ML320 has a check light, BAS light, flashing Low Range light on startup and is stuck in limp mode.

I am getting codes:

C1142 - Lateral Acceleration Sensor, Open/Shorted

different module:
P2061-004
P2061-016
P2061-064

New codes from today:
P114214
P102400

I have replaced the conductor plate, 13-pin connector, and renewed fluid and filter. I also repaired melted wiring going to the 13-pin connector.

None of this made any difference.

Clearing the codes doesn't make any difference. The lights stay off for about a minute, then come back on.

I'm at a loss with this one. I am assuming the Acceleration sensor is a separate issue and will not put the car in limp mode?

Could I be looking at a bad TCM? When I try to access the "Transmission" computer in my scanner it only says "Communication error".
