INITIALIZATION
NOTICE:
- This system requires initializing after changing tires or wheels, or after rotating the tires.
- Be sure to adjust the tire air pressure to the specified value before initialization.
1. INITIALIZING THE TIRE PRESSURE WARNING SYSTEM
(a) Check and adjust the tire pressure to the specified value (Procedure "A").
(b) With the vehicle stopped, turn the ignition switch to the ON position (Procedure "B").
(c) Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks 3 times at 1 second intervals.
HINT: If the tire pressure warning light does not blink, perform the initialization again. (with the ignition switch off, perform the procedure above starting at Procedure "B".)
(d) Drive the vehicle at 19 mph (30 km/h) or more, to complete the initialization of the skid control ECU. (It takes more than one hour.)
HINT: If the tire pressure warning light blinks at 0.25 second intervals while the vehicle is being driven, the initialization may have failed. If so, perform the initialization again. (Turn the ignition switch off and retry from Procedure "A".)
(e) After initialization is completed, the skid control ECU monitors the tire pressure by using the wheel speed sensors.
(f) To verify the system has been initialized check the length of time the tire pressure warning light is on after turning the ignition switch to the ON position.
- Not initialized: 4 sec.
- Initialized: 4 sec.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
