Hello,

I am having an issue with the vehicle listed above SE model. The ABS, ESP, traction etc, all on. Check engine light on. Randomly stalls around 160-190+ (from what I’ve gathered so far anyway).

Issue: stalls randomly and silently shuts off. Usually has to heat up a bit before it turns off, usually around 170+ F. I think. Has issues sometimes turning back on and doesn’t turn over at all. Rough transitions into drive and reverse etc, when it stalls sometimes. It doesn’t do it unless it has stalled. Low voltage and battery light come on when this happens. Battery and alternator just replaced. Doesn’t stall if in park or neutral. 13 codes:

U1110 Mod$00 Confirmed, U0121 ECM Stored, U1110 ECM Stored MIL, U0173 SRS Active MIL, U0176 SRS Active MIL, C2200 ABS Active MIL, C2205 ABS Stored, C1027 ABS Stored, C2100 ABS Stored, C1246 ABS Stored, C1011 ABS Stored, C1032 ABS Stored, C1020 ABS Stored.

It sounds like you have a bad PCM, here is how you can change it out in the images below, you can get a preprogrammed unit by searching Google or Ebay.

Here is the information that makes me think the PCM is bad:

U1110: This code indicates a loss of communication with the electronic control module (ECM). It means that the ECM is not able to communicate with one or more modules in the vehicle's network. Possible causes for this code include a malfunctioning ECM, a wiring issue, or a problem with the network communication system.

U0121: This code points to a communication problem between the ECM and the anti-lock braking system (ABS) control module. It indicates that there is a loss of communication or a communication performance problem between these two modules. The ABS control module is responsible for controlling the vehicle's anti-lock braking system, and if it cannot communicate with the ECM, it may lead to issues with the ABS system.
