level I) are shut down first. Then loads designated as
house loads (priority level II) are shut down. If neces-
sary, basic loads (priority level III) are shut down last.
PLVD allows the driver to continue using critical
loads, while noncritical loads are temporarily unavail-
able. Calculations for disconnecting loads are based
on battery voltage, ignition switch status, and engine
rpm. Also, a time delay is implemented for the shut-
down and reactivation of loads to avoid unnecessary
cycling of loads when battery voltage is close to
shutdown thresholds.
One minute before the comfort loads or house loads
are shut down, the alarm in the instrument cluster
beeps. No alarm sounds before basic loads are shut
down.
If the interior lights have been shut down by PLVD,
pressing one of the interior light switches (if
equipped) brings the interior lights back on.
See
Table 3.1
for the type of loads shut down under
specific conditions.
See
Table 3.2
for the loads that are designated com-
fort, house, and basic load status.
