DIAGNOSIS SYSTEM


  1. Warning light and indicator

    1. When there is a problem with the tire pressure warning system, the tire pressure warning light blinks at 0.5 second intervals, and turns on after 1 minute.

      NOTICE:
      When the malfunction has been corrected, the tire pressure warning light does not turn on.

  2. DTCs (Normal mode)

    1. DTCs are memorized in the tire pressure warning ECU and read by the blinks of the tire pressure warning light or by using a Techstream (YARIS_NCP93 RM000000XMX074X.html).

  3. Test mode

    1. By switching from normal mode into test mode (input signal check), you can inspect the tire pressure warning antenna and receiver, each tire pressure warning valve and transmitter, the engine speed signal and the vehicle speed sensor (YARIS_NCP93 RM000000XN007FX.html).
