Ok, wife's 2005 is showing the following codes; p3021 c1259 P0A80 b1200 c1310 p3000 b1271 b1421 b1207 I'm all ears for answers.
I took it out and checked each module. Only one was low so I changed it out, put it all back together and it's still in same condition. Now, though, it won't even engage to drive as it did before I changed the module. Could the 12v battery be bad and causing this issue?
Did it but red triangle still on. Even disconnected 12v negative for 20 seconds just in case. What to do about triangle? On a good note, all other warning lights went off!
Test drove it after disconnecting neg terminal and locking NGO the safety link and all is well. Thanks for everyone's input, I was tired and at my brains end and you all came through. Great jobs!
Those codes mean something is wrong with those systems. I would first check and make sure your 12v is healthy. Then you would have to address the other problems. They don't just go away because you disconnected the 12v for 20 seconds. They will come back and remind you there is something wrong. Next time you see the warning lights, read them and we can go from there.....
I believe all those codes were caused by lack of power (caused by the safety interlock not properly set). I'm betting his codes don't come back and all is well with that car however, I am betting he will have problems with the battery pack again due to just replacing one module and no rebalancing.
