TIRE PRESSURE WARNING SYSTEM TEST MODE PROCEDURE

  1. Tip:

    • When entering test mode (signal check mode), the tire pressure warning ECU and receiver sets all the test mode (signal check mode) DTCs first. 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.

    • When test mode (signal check mode) returns to normal mode, all the test mode (signal check mode) DTCs will be cleared.

    • Operation of the tire pressure warning reset switch can be checked in test mode (signal check mode).

    • During test mode (signal check mode), the system is not initialized by pushing the tire pressure warning reset switch. The circuit of the tire pressure warning reset switch can be inspected during this mode.

    TEST MODE (SIGNAL CHECK MODE) PROCEDURE

    1. Turn the power switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the power switch on (IG) and the GTS on.

      Tip:

      Every time the test mode (signal check mode) DTC clear conditions are satisfied, the tire pressure warning light illuminated for 1 second. Following this, the tire pressure warning light blinks at 0.125 second intervals.

    5. Press the tire pressure warning reset switch (C2198/98).

    6. 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 (C2181/81 to C2184/84 (C2185/85: w/ Full Size Spare Tire)).

      Tip:

      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.

    7. Check that the tire pressure warning system test mode (signal check mode) DTCs are cleared.
