The tire pressure warning system informs the driver if it detects a low tire pressure. When the tire pressure warning system detects low tire pressure in any of the 4 wheels which affects safe driving, the tire pressure warning light comes on. Tire pressure warning system is controlled by the Brake Actuator Assembly (skid control ECU). When the tire pressure reset switch is pushed, the tire pressure warning light goes off.
RESET PROCEDURES
NOTE: This system requires initializing after changing tires or wheels, after rotating the tires, or when tire pressure warning light blinks twice every second. Set tire pressure within the specified range before initializing. If the tire air pressure is not within the specified range, tire pressure warning system will not function. See INITIALIZING TIRE PRESSURE MONITOR SYSTEM .
NOTE: If the negative battery terminal is disconnected, initialize the following systems after the terminal is reconnected: power window and sliding roof. Refer to owner’s manual or appropriate manufacturer service information.
TIRE PRESSURE MONITOR WARNING LIGHT
When the tire pressure warning light comes on, immediately check the air pressure of all tires. If the tire pressure was normal in all tires, the system needs to be initialized. See INITIALIZING TIRE PRESSURE MONITOR SYSTEM . If a tire is flat, repair as necessary. If a tire inflation is low, adjust to the specified pressure. Push tire pressure warning system reset switch for a few seconds, and make sure the warning light goes off. If the warning light stays on or blinks once every second, there is a malfunction in the TPM system. See appropriate manufacturer service information. If the warning light blinks twice every second, the system needs to be initialized. See INITIALIZING TIRE PRESSURE MONITOR SYSTEM.
