SAFETY 225
• 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 solid, and the instrument
cluster will display a "SERVICE TPM SYSTEM" message for
a minimum of five seconds and then display dashes (- -) in
place of the pressure value.
• Once you repair or replace the original road tire and rein -
stall it on the vehicle in place of the non matching full size
spare or compact spare, the TPMS will update automati -
cally. In addition, the TPM Telltale Light will turn OFF and
the graphic in the instrument cluster 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.
Trailer Tire Pressure Monitoring System (TTPMS)
The Trailer Tire Pressure Monitoring System (TTPMS) is a
feature that will display the trailer tire pressure values and
warn the driver of a low trailer tire pressure, based on the
drivers set target tire pressure value, through the Instrument
Cluster (IC).
The TTPMS monitors the pressure of each tire and warns the
driver, through the IC, when either a low tire pressure condi -
tion or a TPM sensor or system malfunction condition exists.
The IC will display the actual tire pressure or dashes for each
of the trailer tires in the correct trailer position, based on
trailer configuration.
The TTPMS consist of the following components:
• Trailer Receiver Module
• Trailer Interface Module
• Two to twelve tire pressure monitoring sensors depending
on trailer configuration
The TTPMS is configured though the trailer settings menu in
the Uconnect system by selecting the desired trailer number
(up to four trailers can be configured), the number of axles (1
- 3), the number of trailer tires (2, 4, 6, 8, or 12), and the set
trailer tire pressure. Refer to “Uconnect Settings” in “Multi -
media” for further information.
