I am getting some wierd codes in the dash. There WERE 4 of them and now there are only 2 but EVERY time I check the codes on the dash the first one changes by 2. Ex. The code I first got was A4 76 and the second time I checked the codes in the dash I got A4 78 and so on. The other code I get is A8 00 but it hasn't changed yet. When it had 4 codes popping up I took it to the dodge dlrship to have them read the codes and tell me what they mean and one was a TCC Controler Low Voltage. Another was something about an Overdrive sensor (Which is funny because the truck is a 2005 3500 dually 6spd 4X4) The next was an Acceleration Sylanoid Low Voltage and I forget what the last one was...However, I changed the speed sensor on the rear end yesterday and 2 of the codes were gone. I haven't got the chance to go back to the dodge dlrship for lil bit and I am trying to fix it myself but I can't find out what the 2 codes left mean anywhere. I haven't found a list that has the codes that are still coming up. They are : (1st one that changes every time by 2) A4 76 and A8 00. Does anyone know what they mean or perhaps where I may find an archive for the C-Codes listed? (Just to clarify these are not codes generated by turning the key back and forth 3 times. I hold the trip odometer button and turn the key from the off position to the run position and where my odometer is these codes flash after the "C-Code" flashes) PLEASE HELP :CRY:
