Tires, Wheels and Loading 7. Train the TPMS sensors in the tires using the following TPMS reset sequence starting with the left front tire in the following clockwise order: 1. Left front tire (Front driver's side) 2. Right front tire (Front passenger's side) 3. Right rear tire (Rear passenger's side) 4. Left rear tire (Rear driver's side) 8. Left front tire: Place the TPMS reset tool against the left front tire where the tire meets the rim, opposite from the valve stem (1) as shown. This is where the sensor is located inside the rim. The tool needs to be held against the tire sidewall opposite the valve stem as illustrated with the arrow on the tool pointing towards the rim; do not use the tool with the arrow pointing away from the rim as it may not activate the sensor. 9. Press and release the green button and hold the tool to the tire sidewall until the horn sounds. The red light on the TPMS reset tool will illuminate while the tool is active. The horn will sound once within 10 seconds to indicate the process was successful. Note: • If a double horn chirp is heard, repeat the procedure. If a single horn chirp is not heard, move the vehicle to rotate the wheels at least a 1⁄4-turn and repeat the procedure starting with Step 1. • If a double horn chirp is heard even after the wheels were repositioned, contact your authorized dealer as soon as possible. 165 2010 Econoline (eco) Owners Guide, 3rd Printing USA (fus)
