The indicator light does not come on when the ignition
is in LOCK/OFF or if no equipment is plugged into
the outlet.
If you try to connect equipment using more than
150 watts or a system fault is detected, a protection
circuit shuts off the power supply and the indicator
light turns off. To reset the circuit, unplug the item
and plug it back in or turn the Remote Accessory Power
(RAP) off and then back on. See Retained Accessory
Power (RAP) on page 2-27. The power restarts
when equipment using 150 watts or less is plugged
into the outlet and a system fault is not detected.

electrical equipment and may not work properly if
these items are plugged into the power outlet:
• Equipment with high initial peak wattage such
