To reset the ECU just remove the ground off the battery, turn on the headlight switch (will use up any residual power), let it sit for 10 min, and then reconnect the ground on the battery.
Not really sure what you want me to enlighten you on but if you get the code with the Key On Engine Off then its the (O), if you get the code with the Key On Engine Running then its the (R). A Memory code (M) or as some call it a Continuous Memory code (CM) is just that, a code that is stored in continuous memory. The only way to clear the code is to reset the ECU.
The 511 code is generated when you are performing the Key On Engine Off testing. Quick Google search says that is from the chip being installed so no worries there.
Typically driving it around long enough for the motor to get up to operating temperature will do it. Get back to the garage and perform the KOEO tests and then the KOER tests and see what you get.
ok just got back and few questions.....
Do you have to perform the tests with a warm engine? Just curious as I read earlier where you want to and I did it before the fact cold. I then did it again after warming it up and the only differences I got was during the koer the cold got a 116 which is ECT sensor something but all related to the codes 113,117 in the manual out of range or below a certain temp or something. When the car was warm I got a 111 system pass so I figured that was no biggie but that might seem that indeed the car needs to be warmed up.
I read somewhere where both fans are supposed to come on cycle at the start of the koeo test, is that so? I only heard one with mine and sounds like the high speed. IIRC though in the past and over the years I think I just heard one fan; can't totally remember.
at the start of the koer test I am only getting 4 flashes and not 8
still not getting a cylinder balance test to be performed and I even made sure to tap the throttle right after the 111 test. Maybe because the idle hung for that period of time before giving the code that's outside of the range to do the cylinder balance but I didn't get code 538 that's for something along the lines of invalid cylinder balance test due to throttle movement.
I'm going to reset the idle and put it back to where it was prior to the other day and that should be where it was when the tune was done. I will see if that solves the IAC situation during the test of rasing to 1500-2k and staying there until I hit the throttle.
other than that I got a code 111 during the koer test. The throttle raised for a while then came back down and presented 111.
Also 111 during the koeo test after the 511 and 564 which are nothing. That 111 system pass was during the CM process so good on that front?
On another forum this guy mentioned this about the CM or KAM process and getting code 15, then code 15 disappearing, unless that's fox related?
Checking codes is perhaps the most important step in diagnosing problems with your 5.0. It is free, easy, and effective. Materials Needed -a paperclip or a piece of wire approximately 3-10 inches -pen and paper *To get accurate results it is important that the car is fully warmed up Step One...
