: I got the codes, now what?

08-20-04, 02:56 PM
First of all, sorry, I'm learning here thanks to you all, so just asking for more help. It's sensory overload for me, but I'm loving learning all this new stuff! :bighead:

I had a transmission post yesterday and found that most of you believe it's a solenoid issue. I was told to get the codes, so I found out how to do that. I have the codes, but I'm not sure if the lists I'm checking them against are where I need to be looking. Here is my car info, and the codes I rec'd. Sorry if I'm putting too much on here.

96 Deville 4.6L Northstar


PCM 0603 History
PCM 0741 Current
PCM 0756 Current
PCM 1406 History
PCM 1520 History
PCM 1552 History

I'm assuming from what I've read that the History items are no longer issues. I've seen people say to clear them, but I do not know how to do so. Any assistance on these issues, where to find what this means, how to fix it, where to get parts, etc. Thank you all SO very much! I'm not worthy! :worship:

Go to the top of the page and you can get the code definitions. Your car is OBDII.
History codes mean that there was but no longer is a fault detected. When a fault is detected it sets a current DTC. After 3 ignition cycles with no fault it goes to history. After 50 ignition cycles with no fault it gets deleted unless you do it prior by using the hi fan button to answer yes when prompted PCM? after the codes. Then use the low fan button to answer no the the next prompts til you get to CLEAR PCM CODES?.Then answer yes with the hi fan button.

Thank you Ranger, but I have a question about your reply...

Where are you referring to when you say "Go to the top of the page and you can get the code definitions." I don't see a link anywhere?
