Help with codes from DIC

690 Views 1 Reply 2 Participants Last post by  Ranger
First of all, I have a 97 STS. Everything seems to be working fine on it (except for the passengers front window, but that's another story), but just about a week ago my Service Engine Soon light came on and stayed on. Today, I got the following codes from the DIC:

P0300 - Engine Misfire Detected
P0741 - TCC System Stuck Off
B1552 - Keep Alive Memory (KAM) Error
B2710 - PASSKey Open/Shorted Pellet
U1255 - Class 2 Communication Malfunction (Serial Data Line Malfunction)
B1341 - Air Mix Door Two Movement Fault

All I have is a crummy Chilton Manual, so most of the codes weren't even listed in there. I looked those up from the sticky at the top of the forum. I'd just like to know what the problem is here and if it is anything I should worry about. Like I said, the car seems to run fine, but I just would like to know what is wrong since the light came on. I'd really appreciate if some of you guys around that I'm sure know much more than me about these Northstars could help me out. Thanks in advance.

Only the first two DTC's will trip the SES light. Has the fuel rail recall been done recently? A misfire afterwards is not uncommon and new wires solves it.

P0741 is an expensive repair as the trans has to come out, but it is one that you can live with. Do a search for it as it has been discussed many times.

If you are going to do your own work, ditch the Chiltons and get a FSM by Helm Inc. Ebay is your friend.
