I need some help with these codes they are getting annoying and they seem to randomly spring up for no reason...

B1341 - Air Mix Door Two Movement Fault - I assume that this has something to do with the heater...maybe

C1224 - Right Rear Wheel Speed Sensor Input Signal is 0 - I mean I get what it means, but how do I fix it...

U1064 - Loss of Communications with DIM - What is a DIM, and what lost communication with it?

U1128 - Loss of Communications with IRC - Again what is an IRC and what did it lose communication with?

P0174 - Fuel Trim System Lean Bank 2 - Again I get what it means, but what is the problem...


Sorry I'm reatarded...any help would be GREAT

B1341 is indeed the heater. It means that the air mix door is not in the commanded position. It may not be off enough to bother with if your heater is working OK.

C1224 might be a bad wheel speed sensor. It is integral to the hub & bearing assembly. Check the connector on the back of the hub to be sure it is clean and tight. If OK, run a continuity test on the pins from the hub (not the connector with the wires attached). If no continuity, R & R the hub & bearing assembly.

Forget the "U" codes. Could be from pulling battery power. DIM = Dash Integration Module. IRC = Integrated Radio Chassis.

P0174 might be a vacuum leak on the left bank.
