Engine/Transmission (1998.5 - 2002) Code questions

[BSmalley]

Hey all, I have a 2001. 5 HO 6spd. I have posted a few questions over the last few weeks with some problems I have been having. Thanks to HuffnPuff and Snoking for thier input. Have done the clean connections to ground thing and doesn't seem to be any difference. I guess I'm going to be calling a dealer this week. Hopefully this dealer will be better than the last one I dealt with. Anyway, the reason for this post is that this morning I checked the codes on my truck again and it has thrown two new ones that I can't find either in my manual or on line at the code sites posted here. Wondering if anyone has any input. They are in the ECU and they are 0343 and 0577. I had several more, but all those I found in the book. These two I can't find listed anywhere. Also last week, the truck was showing APPS voltage too low, today it is showing 1286, APPS volts too high..... Any help ????????

Thanks,

Bill

PS. Also noticed that yesterday, there were 8 codes set in ECU 2 in PCU. This morning, there were still the same two in the PCU but there were 8 new codes in the ECU. In the order they came up, the only one that was the same was the very last one, 0606-ECM Failure, which was the first one yesterday. Does the odometer only hold/read out 8 codes at a time? Are the other previous codes still set there?

I have been getting the P-0123 code for the last few weeks, APPS switch A circuit high input! Got in it Sunday and now have the APPS P-0122 voltage to low

I'm ditching this POS APPS and getting a new one this week, all for the low low price of $400 samolleys!!!!
