Voltmeter Operation:
•
The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation
is caused by the post-heat cycle of the intake mani-
fold heater system. The number of cycles and the
length of the cycling operation is controlled by the
engine control module. Post-heat operation can run
for several minutes, and then the electrical system
and voltmeter needle will stabilize.
•
The cycling action will cause temporary dimming of
the headlamps, interior lamps, and also a noticeable
reduction in blower motor speed.
