Tire Pressure Monitoring System - Chrysler 2005 Crossfire SRT6 Service Manual

22 - 48 TIRES/WHEELS - SERVICE INFORMATION
Note: TPM thresholds have been established for the original tire size equipped on the vehicle. Use original
size tires only to maintain system accuracy.
DIAGNOSIS AND TESTING - TIRE PRESSURE MONITORING SYSTEM
Diagnostics for the electronic components of the Tire Pressure Monitoring System can be done using the DRB III
scan tool and Appropriate Diagnostic Information.
The Tire Pressure Sensors/Transmitters and TPM module are not repairable components. If either of these compo-
nents are found to be at fault or damaged, the component must be replaced. (Refer to 22 - TIRES/WHEELS/TIRE
PRESSURE MONITORING/MODULE - REMOVAL).

MODULE
DESCRIPTION
The Tire Pressure Monitoring (TPM) System utilizes a
control module (1) to control the system. The TPM
module (1) is located in the headliner between the
dome lamp and the rear view mirror.
OPERATION
The Universal Garage Door Opener/Tire Pressure Monitor (TPM) module has a microprocessor controller that can
monitor the transmissions from the sensor/transmitters anytime the ignition is on. It can store the last 32 transmis-
sions. There are two important values included in these transmissions. They are:
• Why The Transmission Was Sent
• Tire Pressure Value
The module compares the transmitted tire pressure to the two pressure thresholds (low pressure or critical pres-
sure). If the module determines that the tire pressure transmitted is below the low or critical pressure thresholds, it
will signal for the "Low Tire" pressure warning lamp to come on.
