Engine/Transmission (1998.5 - 2002) "No Response From ECM" - Is it Bad?

[HeavyHauler]

Hey guys, I've tried to have the 3-cylinder high idle feature activated twice with the DRBIII showing that the ECM is not responding. I've tried it with my EZ plugged in and unplugged and got the same results. There aren't any codes either.



Has anyone else had this problem and should I take it into the dealer again and try to get them to replace it?



Thanks for the help - I want to try to get this taken care of before my warranty expires.

Audio Check! Is this thing getting out?

if you search the archive for the 3 cylinder cold idle reflash, there is a ton of information



The dealer's even have a PITA trying to get the high idle enabled. your ecm is fine
