### Learn Mode Description

The Tire Pressure Monitor (TPM) System uses the instrument panel cluster (IPC), tire pressure monitor receiver, 4 radio frequency transmitting pressure sensors, and the serial data circuit to perform the TPM learn mode functions. The sensor learn procedure must be performed after a tire pressure indicator receiver replacement or any sensor replacement. Once the vehicle learn mode has been enabled, each of the sensors unique identification codes can be learned into the receiver memory and will be displayed as Valid on the scan tool.

### TPM Learn Procedure

Important: Before proceeding, ensure that no other learn procedure is being performed simultaneously within close proximity. Stray signals from other TPM equipped vehicles just driving by can be inadvertently learned. Under these circumstances, performing the TPM Learn Procedure away from other similar vehicles would be highly recommended.

1. Adjust all tires to the recommended pressures. Refer to Vehicle Certification, Tire Placard, Anti-Theft, and Service Parts ID Label.
2. With a scan tool, perform the Program ECU function and follow the screen prompts.
3. Drive the vehicle over 32 km/h (20 mph) until each TP Sensor ID Status is displayed as Valid, all TP Sensor Pressure readings are present, and the Learn Status is displayed as Completed.
