Well I finally purchased a Tech2 Clone thinking this will help me figure out whats going on with my two 2006 9.3 Aero convertibles. Bot have been dealing with stability control/ABS codes. The AC stops working gauges freeze when the ABS lights up and it will disappear and gauges start working again and a host of related issues for a while now and finally rendered both of them parked in the garage.

Silver car had the stability control issue for the previous owner as well but I was able to get it running again by replacing the battery that did not hold charge and by doing the relay jump. It ran great for 6 months until one morning when the dreaded triangle showed up on the dash.

ESP+ 2105 00
ECM missing on bus


Is there a approach to determine if the ECM is bad?


Thanks,

Tom
