  3. INITIAL CHECK


    1. An initial check is performed when the engine switch is off for more than 2 seconds and then turned on (IG). The initial check consists of a pre-collision system diagnostic check with a duration of approximately 3 seconds.

    2. If a malfunction is detected during the initial check, the PCS warning light in the combination meter assembly will blink and a warning message indicating the pre-collision system is malfunctioning or disabled will be displayed on the multi-information display.

  4. CONSTANT CHECK


    1. The driving support ECU assembly constantly monitors the pre-collision system for malfunctions after the engine switch is turned on (IG) and the initial check (approximately 3 seconds) has completed.

    2. If a malfunction is detected during the constant check, the PCS warning light in the combination meter assembly will blink and a warning message indicating the pre-collision system is malfunctioning or disabled will be displayed on the multi-information display.
