Perform Mitsubishi TPMS Sensor Relearn Procedure

If the Mitsubishi TPMS is failing to learn new sensor IDs, a specific relearn procedure must be performed. This process ensures the vehicle's TPMS control unit correctly recognizes and communicates with all installed tire pressure sensors.

1. Prepare the Vehicle: Ensure all tires are inflated to the manufacturer's recommended pressure, as specified on the driver's side door jamb placard.
2. Engage Learn Mode: Refer to your Mitsubishi owner's manual for the specific steps to put your vehicle into TPMS learn mode. This often involves a sequence of ignition cycles and button presses.
3. Activate Sensors: Using a dedicated TPMS scan tool, activate each new or existing TPMS sensor, starting with the front left tire and proceeding clockwise (front right, rear right, rear left). The scan tool will transmit the sensor's ID to the vehicle's TPMS control unit.
4. Drive Cycle: After activating all sensors, drive the vehicle at a speed above 15 mph (25 km/h) for at least 10-20 minutes. This driving cycle allows the system to fully register the new sensor IDs and confirm tire pressure readings.
5. Verify Resolution: Confirm that the TPMS warning light on the dashboard has turned off. If the light remains on, repeat the procedure or consult a professional technician.

Tools/Materials Needed: A TPMS scan tool compatible with Mitsubishi vehicles, and a reliable tire pressure gauge.

Safety Precaution: Always perform this procedure in a safe location, and ensure tires are properly inflated before driving to avoid unsafe conditions.
