I have a 2000 f250 that is pretty much stock with the exception of a 10k mod that's been on the truck for about 3-4 yrs now.
On to the problem now. The other night I plugged up a innova 3150 to the truck to see if there were any soft codes or anything. There was a few that came up like the EBP sensor and then the rom error code. I reset and the rom error won't clear out even with disconnecting the batteries. My other thing is that I tried to run the KOER test and after doing the prompts that it says to do it will not do anything. The tester says that it's testing but that's all it will do. We left it plugged up with the truck running for about 10-15 mins and nothing happened. I unplugged the scanner and the truck shut off within a few sec by its self. Tried it again and same result again. We then tried it on a 99 f250 and got the rom error code. We tried the KOER test on it and within a few sec it was doing its thing. The truck started running crazy then idiled up kinda high and then the EBPV closed for a few sec and it started running fine again.
What would cause my truck to not do any of this? And what exactly is the KOER test checking for?
