Does anyone know the location of the PCM fuse on a 2001 VX? The shop manual instructs to check the 30A PCM fuse, but I checked the two fuse boxes, and could not see anything label as a PCM.

Thanks for your help

its most likely labeled ECU or ECM on the fuse box

I looked at Main fuse box under the hood and there was only one fuse labeled ECM (EB-18) but it is a 40A fuse, the manual says to replace a 30A PCM fuse...was that a typo? What is the rating on yours?

Thanks a lot for your reply...I am trying to solve an issue with the "Engine Fuse CB-3" constantly blowing. The shopmanual instructs to check the 15A engine fuse, the 30A PCM fuse and to check for short to ground in the PCM ignition and battery feed circuits...which I don't know where they are. The engine fuse blows the second I turn the key on...before the engine cranks.

The shop manual I downloaded from this site was for model year 2000, did Isuzu go from a 30A to 40A ECU fuse on the 2001 VX models? I do have a 40A ECU fuse under the hood
