(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON.
(d) Turn the Techstream on.
(e) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / Signal Check.
HINT:
Every time the test mode DTC clear conditions are satisfied, the tire pressure warning light turns on for 1 second. Then, the tire pressure warning light blinks at 0.125 second intervals.
(f) Start the engine and allow it to run at 1000 rpm for 3 seconds or more to check the engine speed signal (C2194/94).
(g) Drive the vehicle at 20 km/h (12 mph) or more for 3 seconds or more to check the vehicle speed signal (C2191/91).
(h) Loosen the valve core and rapidly reduce the pressure by at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds to check the transmitter data (C2181/81 to C2184/84 or C2185/85*).
HINT:
The transmitter ID can be transmitted by rapidly reducing the tire pressure.
(i) Check that the tire pressure warning system test mode DTCs are cleared.
