Hi all, I am getting DTC code U1000 in a 2004 coupe with 75,000 miles. I'm seeing that the code is related to the PCM but seems to be very high level. The car shuts down to "reduced power" mode and all kinds of warning lights will pop on and off randomly . I'm wanting to ask if anyone has experienced this problem and they can let me know that solution and where/what do I need to check? Thanks.
