• One way to verify diagnostic data from the

GPCM is to measure the amperage draw
with an inductive amp probe.

• Once the glow plug system has been

commanded on by the PCM (when engine
temperature is warm you may need to trick
the system into a cold condition) for about
40 sec., the glow plug amperage should be
stable. Each glow plug should draw between
10-12 amps.

• When testing the glow plug system, it is best

to measure one bank of glow plugs at a
time. The bank with the lower current draw
would be the bank with the bad glow plug
and/or wiring concerns.
