On EC-179, it shows that the ECM (ECCS Control Module) throws code 31 when it malfunctions.......

Thanks Man...

Yes...we did that testing...but not the ECM test.
What a pain in the Arse !

I'm seriously considering selling this year truck and looking for a OBDII system. I feel sorry for the mechanics and end-users of the OBDI system... its like i'm reading / looking for smoke signals with the flashes, etc.----not to mention the location of it. My Ass and knees are scabbed !
