I recently ran a self test and these trouble codes came up...

AMP U1064
DIM B1324
PCM P0741

Can anyone please help me with these.. I need to know what they mean and if possible how to fix them...

Thanks...

 

P0741 is the one to worry about. Normally internal trans problem, averages over 1800 - 3k to fix.

 

U1064 - Loss of communication with dash integration module. (If everything inside is working properly, it will most likely clear itself)

B1324 - Refrigerant overpressure. (Possibly a clogged expansion orifice. Can occur "normally" in EXTREMELY hot & humid weather.)

P0741 - Torque converter clutch stuck. (Judging by my experience with a Seville STS, that one's going to be EXPENSIVE!)
