Have the Ecm checked At dealers ( recall )
I checked with my local Honda dealership and they quoted me around $1,350. Ouch.
If at all possible have the ECM checked out or replace. Have had this issue with the Grenadas and Cougars. Each one turned out to be the ECM.
only two things left in the system are the ecm and the wiring... check for power on all circuits before replacing the ecm...
replace the ecm
You need to have the ECM (engine computer), not the PCM, checked for trouble codes. You will then know what to diagnose.
where is the ECM located on my 2000 Jimmy? where is the ECM located on my 2000 Jimmy?
ecm stands for electronic control module
you can't fix an ecm, you have to replace it.
There are no ECM hoses. The ECM is the Electronic Control Module.
Computer (ECM) does a self test of components and has found a part that is out of the specified range and turns on the check engine light so that you get it checked out so that the problem doesn't get worse.
no ECM's in a 1981
