TEST MODE PROCEDURE
1. TEST MODE (SIGNAL CHECK MODE) PROCEDURE
HINT:
After the tire pressure warning ECU and receiver completes the signal check for each inspection item, the DTCs for systems that are determined to be normal will be cleared. The DTCs for other inspection items may not be cleared when only a certain signal is inspected.
(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON and the Techstream on.
(d) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / Signal Check.
*a |
0.125 sec. |
*b |
ON |
*c |
OFF |
HINT:
Every time the test mode (signal check mode) DTC clear conditions are satisfied, the tire pressure warning light illuminates for 1 second. Following this, the tire pressure warning light blinks at 0.125 second intervals.
(e) Press the tire pressure warning reset switch (DTC C2198/98).
(f) Wait for 1.5 minutes with the vehicle stopped, or drive the vehicle at a speed of 50 km/h (31 mph) or more for 1 minute (DTCs C2181/81 to C2184/84).
HINT:
The tire pressure warning valve and transmitters send signals to the tire pressure warning ECU and receiver once every 1.5 minutes while the vehicle is stopped and once every minute while driving.
(g) Check that the tire pressure warning system test mode (signal check mode) DTCs are cleared.
