TEST MODE PROCEDURE
1. ENTER TEST MODE (SIGNAL CHECK MODE)
(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON.
(d) Check that the tire pressure warning light comes on for 3 seconds and then goes off.
(e) Turn the Techstream on.
(f) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / Signal Check.
(g) Confirm that the tire pressure warning light in the accessory meter blinks at 0.125 second intervals.
2. PERFORM SIGNAL CHECK
HINT:
(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 conditions to clear signal check DTCs are met, the tire pressure warning light comes on for 1 second. Following this, 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 each valve core and rapidly reduce the pressure (at least 40 kPa (0.4 kg/cm2, 5.8 psi) within 30 seconds) to check the transmitter data (C2181/81 to C2184/84).
HINT:
The transmitter ID will be transmitted if the tire pressure is reduced rapidly.
(i) Check that the tire pressure warning system signal check DTCs are cleared.
