Perform Mitsubishi TPMS System Reset

This procedure describes how to reset the Tire Pressure Monitoring System (TPMS) on most Mitsubishi vehicles once tire pressures are confirmed to be correct and no sensor faults are present. This often resolves the warning light after tire rotations or adjustments.

1. Inflate All Tires: Ensure all four tires are inflated to the manufacturer's recommended PSI. This information is typically found on a sticker inside the driver's door jamb.

2. Turn Ignition ON: With the vehicle parked, turn the ignition to the "ON" position (engine off).

3. Locate TPMS Reset Button (if applicable): Some Mitsubishi models may have a dedicated TPMS reset button, often located under the dashboard near the steering column. If present, press and hold it until the TPMS light blinks three times, then release.

4. Drive the Vehicle: If no dedicated button is found, or if the light remains on, drive the vehicle at a speed above 15-20 mph (25-30 km/h) for at least 10-20 minutes. The system requires driving time to relearn the sensor IDs and pressure values.

5. Verify Reset: The TPMS warning light should turn off automatically once the system successfully completes its relearn process. If the light remains on, repeat the driving cycle or consult your owner's manual for model-specific instructions.

Safety Precaution: Always ensure tires are correctly inflated before driving. Do not rely solely on the TPMS light as a substitute for regular manual tire pressure checks.
