Initializing Tire Pressure Monitor System
CAUTION:
Do not push the reset switch without adjusting tire inflation pressure. Otherwise, the low tire pressure warning light may not come on even if the tire pressure is low, or it may come on when the tire inflation pressure is actually normal. If you push the reset switch while the vehicle is moving, initialization is not performed.
- Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
- With vehicle stopped and parking brake applied, turn ignition switch to ON position.
- Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks 3 times at one-second intervals. See Fig 1.NOTE: If the tire pressure warning light does not blink, turn ignition switch to OFF position and perform the initialization procedure again starting at step 2. If light still does not blink, there is a problem in the TPM system. See appropriate manufacturer service information.
- Drive the vehicle at 19 mph (30 km/h) or more to complete the initialization of the ABS/skid control ECU (it takes more than one hour). Vehicle should be driven under the following conditions:
- The vehicle speed is between 31-62 mph (50-100 km/h).
- The roads are dry, smooth and straight.
- The number of passengers is 1 or 2 (including driver).
NOTE: 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, turn ignition switch to OFF position and perform the initialization procedure again starting at step 1. - 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. Light will stay on for 3 seconds if system is initialized, or 4 seconds if system is not initialized.
