C1597 Description

 

The Tire Pressure Monitor (TPM) Module determines the TPM Sensor positions by performing the vehicle Tire Pressure Monitoring (TPM) Sensor locate procedure. This procedure is run after the vehicle has been stationary for 20 minutes. After driving the vehicle at speeds greater than 24 km/h (15 mph) for a minimum of 10 minutes without the TPM Sensor installed, the TPM Module sends a bus message commanding the TPM telltale lamp to flash for 75 seconds. After the 75 seconds of flashing, the lamp will remain on solid and a chime will be heard. The message center will display SERVICE TPM SYSTEM for five seconds and shut off, all while the tire pressure values will be displayed as dashes. After the ignition has been cycled off and on the TPM telltale lamp will remain off, the message center will no longer display SERVICE TPM SYSTEM, and the tire pressures continue to be displayed as dashes.
