Hey guys! I have some some issues going on and I'm reading the codes but still not sure what to do. I'm getting service vehicle soon, abs light, service traction control, service active handling system and I have to wait a few minutes to get my air conditioning going. I've been reading up a little on this but still confused with all the information out there. Could really use some help. I have a 2001 standard with 116,000 miles on it.
This is what i'm getting guys:
DTC B2262-B2265
Mirror Position Sensor Signal Circuit
DTC C1277 or P1571
Powertrain Indicated Traction Control Malfunction
DTC C1276, P1644, or P1689
Delivered Torque Circuit
DTC U1000 and U1255
Class 2 Communication Malfunction
DTC U1001-U1254
Lost Communication with XXX
28TCS no comm.
B042 rear defogger relay circuit

When posting U codes we need to know what module they were under. What does "or" mean?

Put a new battery in it

Or at least get the battery and charging system checked to rule out those items.

Like they said above, make sure you have a fully charged battery. Low voltage can create havoc with the electronics in these cars. Been there.

There is a sticky in the C5 tech section on cleaning the ignition switch. Do this first. 100% guarantee that there is oxidation on the contacts.

Had a list of errors on my brothers 2001 that cleaning the ignition switch corrected. This was at about 75K miles about 3 months ago.

The very first thing to check is the battery!
After that you can check anywhere you want.

Thanks for the advice. That will be my next step.

Depending on the battery, you want around 12.6 volts or better, if you're around 12.1 you need to charge it or replace it
