After completing signal check for each inspection item, the DTCs for systems that are determined to be normal by the tire pressure warning ECU will be erased.
The DTCs for other inspection items may not be erased when only a certain signal is inspected.
(a) Make sure that the ignition switch is off.
(b) Connect the intelligent tester to DLC3.
(c) Turn the ignition switch to the ON position.
(d) Select the SIGNAL CHECK on the intelligent tester.
HINT: Every time the test mode DTC clear conditions are satisfied, the tire pressure warning light comes on for 1 second. Then, the tire pressure warning light blinks at 0.125-second intervals.

(e) Drive the vehicle at 12 mph (20 km/h) or more for 10 seconds or more to check the vehicle speed signal (C2191/91).
(f) Loosen the valve core and rapidly reduce the pressure (at least 40 kPa (0.41 kg/cm2, 5.8 psi) within 30 seconds or more) to check the transmitter data (C2181/81 to C2184/84).
HINT: The transmitter ID can be transmitted by rapidly reducing the tire pressure.
(g) Check that the tire pressure warning system test
mode DTCs are erased.
(h) Check the tire pressure warning reset switch.
(1) Press the tire pressure warning reset switch.
(2) Check the tire pressure warning indicator light.
