No KOEO Codes = Failed RAM?

Unread postby yeastieBoB » Sun Jul 15, 2018 12:00 pm

Vehicle: 1995 F150 5.0 auto

I can get KOER codes. I used to be able to get KOEO codes, but not anymore. I read here that "The processor's Random Access Memory (RAM) is tested during KOEO Self-Test. If the processor's RAM has failed, the MIL will light and no codes are output."

Questions:

What impacts does failed RAM have?

What now? Open up the EEC and have a look?

Thanks

A failed RAM test is a serious hardware failure (and does not just affect the KAM). It means that any value held in a failed RAM address will be corrupted and this can lead to all kinds of running problems.

Ah, thanks. I'm surprised it's running at all with a RAM failure. A PC wouldn't even boot if the RAM didn't work.

I guess this explains the miss.

I suppose I need to find a replacement computer.

Replaced the ECM with a remanufactured unit from Cardone (via RockAuto). Passed KOEO/KOER and runs great now.
