OPERATION

The Universal Garage Door Opener/Tire Pressure Monitor (TPM) module (1) has a microprocessor controller that can monitor the transmissions from the Tire Pressure Sensors/Transmitters anytime the Ignition is ON.

The TPM module compares the transmitted tire pressure from the Tire Sensors to the predetermined low pressure threshold. If the transmitted value falls below the low pressure threshold, the TPM module will alert the driver.





The TPM module (1) performs diagnostic routines, and stores Diagnostic Trouble Codes (DTCs). When the TPM module determines there is a fault, the low tire pressure indicator lamp circuit is grounded and the Instrument Cluster turns on the "Low Tire" pressure indicator lamp.

The TPM module (1) also stores its own identification number, each of the four sensor/transmitter identification numbers, module version and the date of manufacture.
