Crossfire SRT-6 V6-3.2L SC VIN N (2005)
Garage Door Opener Transmitter: Description and Operation
The Universal Garage Door Opener/Tire Pressure Monitor Module (1) is located in the headliner near the inside rear view mirror (2). The Tire Pressure
Monitoring (TPM) system utilizes a control module to monitor and operate the system. The control module also has a universal garage door opener
integrated along with it.
The tire pressure monitoring system utilizes transmiffers that are located in the valve stem (1) of each tire (2) to communicate the tire pressure condition
to the module. If a tire has low air pressure, an indicator light on the Instrument Cluster is illuminated. The vehicle operator must check the tire pressure
of each tire in order to determine which tire has a low pressure condition.
The Universal Garage Door Opener/Tire Pressure Monitoring (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 transmissions. There are two important values included in these transmissions.
They are:
-
Why the transmission was sent
-
Low tire pressure
The module compares the transmiffed tire pressure to the pressure threshold. If the module determines that the tire pressure transmitted is below the low
pressure thresholds, it will signal for the "Low Tire" pressure warning lamp to come on.
The TPM module performs diagnostic routines, stores diagnostic trouble codes and provides the appropriate lamp status to the Body Control Module
(BCM). When the module determines there is a fault, the low tire pressure indicator lamp circuit is grounded and the BCM turns on the "Low Tire
Pressure" indicator lamp.
The UGDO/TPM module also stores its own identification number, module version and the date of manufacture.
