Tire Pressure Sensor Relearn

Once the learn mode has been enabled, each of the sensor's unique identification (ID) codes can be learned into the tire pressure indicator receiver's memory and display the tire pressures on an approved scan tool.

NOTE: Before proceeding with the steps below, ensure that no other sensor learn procedure is being performed simultaneously and that no tire pressures are being adjusted on another TPM equipped vehicle within close proximity.

NOTE: In the following procedures, a TPM Sensor Activation Tool (J-46079) may be used in place of increasing/decreasing pressures to enable sensor. To use, place activator antenna against the tire sidewall close to the wheel rim at the valve stem location, then press and release the ACTIVATE button.

NOTE: If TPM Sensor Activation Tool (J-46079) is used, and vehicle is having trouble entering relearn mode, check batteries in activation tool. Low batteries may allow some functions to work, but not allow vehicle to perform learn function. When the internal battery is fresh (fully charged), the indicator is "full" or all dark. When the battery is depleted, the indicator shows "empty" or all light.

Adjust each tire pressure to the recommended tire pressure specifications.
Connect scan tool. Turn ignition switch to RUN position. Apply parking brake.
Using scan tool, perform the "PROGRAM ECU" function and continue to follow screen prompts.
Drive vehicle at a speed of 20 mph (32 km/h) until each tire pressure sensor ID is displayed as valid, each tire pressure reading is present, and the learn status is displayed as "COMPLETED".
