Ignition switch JEEP WRANGLER 2012 JK / 3.G Repair Manual

Preparations For Jump-Start
The battery in your vehicle is located in the right rear of
the engine compartment, behind the Power Distribution
Center.WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is on. You can be injured by
moving fan blades.
•Remove any metal jewelry such as watch bands or
bracelets that might make an inadvertent electrical
contact. You could be seriously injured.
•Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, shift the automatic transmission
into PARK (manual transmission in NEUTRAL) and turn
the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories.

502 WHAT TO DO IN EMERGENCIES

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equip-
ment manufacturer ’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
main structural members of the vehicle, not to bumpers
or associated brackets. State and local laws applying to
vehicles under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the vehicle’s battery is discharged, refer to “Shift Lever
Override” in “What To Do In Emergencies” for instruc-
tions on shifting the automatic transmission out of the
PARK position for towing.CAUTION!
•Do not attempt to use sling type equipment when
towing. When securing the vehicle to a flatbed
truck, do not attach to front or rear suspension
components. Damage to your vehicle may result
from improper towing.
•If the vehicle being towed requires steering. the
ignition switch must be in the ON/RUN or ACC
position, not the LOCK/OFF position.
Towing Without The Ignition Key Fob
Special care must be taken when the vehicle is towed
with the ignition in the LOCK/OFF position. The only
approved method of towing without the ignition key is
with a flatbed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.

the message will appear the next time the vehicle is
started. This might indicate a damaged cap. If the prob-
lem is detected twice in a row, the system will turn on the
MIL. Resolving the problem will turn the MIL off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing. Normally, the OBD II system will be ready. The OBD II
system may
notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Turn the ignition switch to the ON position, but do not
crank or start the engine.
2. If you crank or start the engine, you will have to start
this test over.
3. As soon as you turn the ignition switch to the ON
position, you will see the MIL symbol come on as part of
a normal bulb check.

CAUTION!
•When installing the Integrated Power Module
cover, it is important to ensure the cover is prop-
erly positioned and fully latched. Failure to do so
may allow water to get into the Integrated Power
Module, and possibly result in an electrical system
failure.
(Continued)
CAUTION! (Continued)
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage rating.
The use of a fuse with a rating other than indicated
may result in a dangerous electrical system over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than
21 days, you may want to take steps to protect your
battery. You may:
•Remove Cartridge fuse #J13 in the Power Distribution
Center (PDC) labeled Ignition-Off Draw (IOD) and
store it in a safe location within the PDC.
•Or, disconnect the negative cable from the battery.
