Tires, Wheels and Loading 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 driver's door. See Vehicle loading - with and without a trailer in this chapter for more information. Overview Note: Before performing either of the TPMS reset procedures below refer to Changing tires with TPMS earlier in this section to familiarize yourself with the type of wheels and pressure sensors on your vehicle. To provide the vehicle's load carrying capability, some vehicles require different recommended tire pressures 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 lamp at two different pressures; one for the front tires and one for the rear tires. Since 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 3 feet (1 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 procedure will have to be repeated on all four wheels. • A double horn chirp indicates the need to repeat the procedure. Note: Two TPMS reset procedures are given below: one for tires with snap-in sensors and one for tires with banded sensors. 160 2010 Econoline (eco) Owners Guide, 3rd Printing USA (fus)
