The Glow Plug Monitor Self Test (California only) is a KOER functional test of the glow plug system performed on demand with the engine running and the A/C off. The PCM will activate the Glow Plug Control Module (GPCM) which monitors the glow plug. The pedal may be used to increase the engine speed to increase voltage if needed Subtract the resistance value of your multimeter from the resistance value of your glow plug. For example, if your plug's resistance measured.9 ohms and your meter's resistance measured.2 ohms, the real reading for the plug is.7 ohms. All the glow plugs in your engine should have similar readings Replaced all glow plugs with MC plugs (I'm thinking the orignals may have been fine now). Contoller clicks loudly and rapidly, WTS light goes on for half a second and then out, Normal long click at start is not happening. Cleaned the ground for Timmer. WTS now comes on and cycles for the correct duration, but no click from the GPC 1.Make sure the battery has a full charge 2.At the glow plug connector (GPC) on the right side valve cover, check for battery voltage on the large black/yellow wire. If that's present, check for battery voltage at the smaller red wire (key on)
as you said, p0380 usually indicates 1 or more bad glow plugs, g/p controller, or the 175 amp fuse. check the glowplugs first. take the rail off of them and get a test light, hook it to the pos side of the battery and touch the tip of each glowplug. if it lights up the glowplug is bad Tip: For most glow plugs, the acceptable range for the true resistance value is between 0.1 and 6 Ohms. Step 9: Repeat for other glow plugs. Repeat the procedure for the remaining glow plugs, until they have all been tested. If any of the glow plugs fail the test, it is recommended that the entire set be replaced 2. Glow Plug Light comes on.
