Tire Pressure Warning Reset Switch: Description and Operation

1. TIRE PRESSURE WARNING RESET SWITCH

- By operating the tire pressure warning reset switch, the tire pressure warning ECU and receiver can be set to issue a warning at an inflation pressure that corresponds to the type of tires. Therefore, the dealer must set the warning threshold to the proper value in order to comply with local regulations.
- Operate the tire pressure warning reset switch only after the inflation pressures of all tires have been adjusted on the vehicle.
- To initialize the system, press and hold the tire pressure warning reset switch for 3 seconds or longer with the ignition switch ON. After the system has been initialized, the warning light blinks 3 times (1 second on, 1 second off).
- During initialization, the tire pressure warning valve and transmitter measures the inflation pressure of the tires, and registers the signals that are transmitted into the tire pressure warning ECU and receiver at a frequency of one per minute. The initialization process is completed when the signals from all tires have been received.

6. TIRE PRESSURE WARNING SELECT SWITCH

- This switch is installed at the base of the instrument panel on the passenger seat side.
- The tire pressure warning ECU and receiver can be used to register two sets of transmitter IDs, and can select one or the other using the tire pressure warning select switch. Consequently, there is no need to register the transmitter IDs again each time a tire set is changed.
