Tire Monitoring System: Service and Repair

Tire Pressure Monitoring System (TPMS) Reset

When Inflating your tires:
When putting air into your tires, the tire pressure monitoring system may not respond immediately to the air added to your tires.

It may take up to two minutes of driving over 20 mph (32 km/h) for the light to turn off after you have filled your tires to the recommended inflation pressure.

TPMS reset procedure
The TPMS reset procedure needs to be performed after each tire rotation on vehicles that require different recommended tire pressures in the front tires as compared to the rear tires.

WARNING: To determine the required pressure(s) for your vehicle, refer to the Safety Compliance Certification Label or Tire Label located on the B-Pillar or the edge of the drivers door.

Overview
To provide the vehicle's load carrying capability, some vehicles require different recommended tire pressure in the front tires as compared to the rear tires. The tire pressure monitoring system (TPMS) equipped on these vehicles is designed to illuminate the low tire pressure warning light at two different pressures; one for the front tires and one for the rear tires.

Since the tires need to be rotated to provide consistent performance and maximum tire life, the tire pressure monitoring system needs to know when the tires are rotated to determine which set of tires are on the front and which are on the rear. With this information, the system can detect and properly warn of low tire pressures.

TPMS reset tips:
- To reduce the chances of interference from another vehicle , the TPMS reset procedure should be performed at least three feet (one meter) away from another Ford Motor Company vehicle undergoing the TPMS reset procedure at the same time.
- Do not wait more than two minutes between resetting each tire sensor or the system will time-out and the entire process will have to be repeated on all four wheels.
- A double horn chirp indicates the need to repeat the procedure.

Performing the TPMS reset procedure

It is recommended that you read the entire procedure before attempting.

1. Drive the vehicle above 20 mph (32 km/h) for at least two minutes and then park in a safe location where you can easily get to all four tires and have access to an air pump.
2. Place the ignition in the off position and keep the key in the ignition.
3. Cycle the ignition to the on position with the engine off.
4. Turn the hazard flashers on then off three times. This must be accomplished within 10 seconds.

If the reset mode has been entered successfully, the horn will sound once, the TPMS indicator will flash and the message center (if equipped) will display TRAIN LEFT FRONT TIRE. If this does not occur, try again starting at step 2.

If after repeated attempts to enter the reset mode, the horn does not sound, the TPMS indicator does not flash and the message center (if equipped) does not display TRAIN LEFT FRONT TIRE, advanced diagnostics will be necessary.

5. Train the TPMS sensors in the tires using the following TPMS reset sequence starting with the left front tire in the following clockwise order:
- Left front (Driver's side front tire)
- Right front (Passenger's side front tire)
- Right rear (Passenger's side rear tire)
- Left rear (Driver's side rear tire)
6. Remove the valve cap from the valve stem on the left front tire; decrease the air pressure until the horn sounds.

Note:The single horn chirp confirms that the sensor identification code has been learned by the module for this position. If a double horn is heard, the reset procedure was unsuccessful and must be repeated.

7. Remove the valve cap from the valve stem on the right front tire; decrease the air pressure until the horn sounds.
8. Remove the valve cap from the valve stem on the right rear tire; decrease the air pressure until the horn sounds.
9. Remove the valve cap from the valve stem on the left rear tire; decrease the air pressure until the horn sounds.

Training is complete after the horn sounds for the last tire (drivers side rear tire), the TPMS indicator stops flashing, and the message center (if equipped) displays TRAINING COMPLETE

10. Turn the ignition off. If two short horn bursts are heard, the reset procedure was unsuccessful and must be repeated.

If after repeating the procedure and two short beeps are heard when the ignition is turned off, additional diagnostics are required.

11. Set all four tires to the recommended air pressure as indicated on the Safety Compliance Certification Label or Tire Label located on the B-Pillar or the edge of the drivers door.
