First off let me say hi to everyone as I'm new to the board.
So I got a Service Engine Soon light a couple weeks back. Pulled the codes in the thread topic. Ive researched it a bit and just now had the chance to go through it. I've pulled the GPCM green and black plugs/connector to test the circuits to the glow plugs. Here are the values
Black harness That connects to GPCM
Glow plug 8 - .5
Glow plug 6 - .3
Glow plug 4 - .4
Glow plug 2 - .4
Green Harness that Connects to GPCM
.4 / .4 / .5 / .6-7
The values from the connector to the glow plugs seem to be in range. Is it safe to say that the GPCM is bad and that is the part i should be replacing? Should I check something else?
