3. Lots of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM
sensors.
The “TPM Telltale Light” will also flash on and
off for 75 seconds and then remain on, and the
EVIC will display aSERVICE TPM SYSTEM
message when a system fault is detected pos-
sibly related to an incorrect sensor location
fault. In this case, the SERVICE TPM SYSTEM
message is then followed by a graphic display,
with pressure values still shown. This indicates
the pressure values are still being received
from the TPM Sensors. However, the system
still needs to be serviced as long as the SER-
VICE TPM SYSTEM message exists.
NOTE:
There is no tire pressure monitoring sensor
in the spare tire. The TPMS will not be able to
monitor the tire pressure. If you install the
spare tire in place of a road tire that has a
pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a
chime will sound, the TPM Telltale Light will turn on, and the EVIC will still display a
Low Pressure message and a “flashing”
pressure value in the graphic display. After
driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the
TPM Telltale
Light will flash on and off for 75 seconds
and then remain on, the EVIC will display a
“SERVICE TPM SYSTEM message and then
display dashes (- -) in place of the pressure
value. For each subsequent ignition switch
cycle, a chime will sound, the TPM Telltale
Light will flash on and off for 75 seconds
and then remain on, the EVIC will display a
SERVICE TPM SYSTEM message and then
display dashes (- -) in place of the pressure
value. Once you repair or replace the origi-
nal road tire, and reinstall it on the vehicle in
place of the spare tire, the TPMS will update
automatically.
In addition, the graphic in the EVIC will display
a new pressure value instead of dashes (- -), as
long as no tire pressure is below the low-
pressure warning limit in any of the four active
road tires. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.TPMS DeactivationThe TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies that do not have
TPMS Sensors, such as when installing winter
wheel and tire assemblies on your vehicle To
deactivate the TPMS, first, replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
(TPM) Sensors. Then, drive the vehicle for
20 minutes above 24 km/h (15 mph). The TPMS
will chime, the TPM Telltale Light will flash on
and off for 75 seconds and then remain on and
the Electronic Vehicle Information Center
(EVIC) will display the “SERVICE TPM SYSTEM”
message and then display dashes (--) in place
of the pressure values. Beginning with the next
ignition switch cycle, the TPMS will no longer
chime or display the “SERVICE TPM SYSTEM”
message in the EVIC but dashes (--) will remain
in place of the pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPM sensors. Then, drive the
vehicle for up to 20 minutes above 24 km/h
(15 mph). The TPMS will chime, the TPM

CAUTION!
•
When installing the totally integrated power
module cover, it is important to ensure the
cover is properly positioned and fully
latched. Failure to do so may allow water to
get into the totally integrated power module
and possibly result in a electrical system
failure.

CAUTION!(Continued)
• When replacing a blown fuse, it is important
to use only a fuse having the correct am-
perage rating. The use of a fuse with a
rating other than indicated may result in a
dangerous electrical system overload. If a
properly rated fuse continues to blow, it
indicates a problem in the circuit that must
be corrected.
VEHICLE STORAGEIf you are leaving your vehicle dormant for more
than 21 days you may want to take steps to
protect your battery. You may:
•Remove fuse #J13 in the Totally Integrated
Power Module (TIPM) labeled Ignition-Off
Draw (IOD#1).
• Or, disconnect the negative cable from the
battery.
