Fail-safe

FAIL-SAFE FUNCTION

  • A/C amp. performs fail-safe control when any DTC are detected.

    DTC CONSULT screen terms (Trouble diagnosis content) Fail-safe
    B24A6-11 IN-Nissan Ariya Vehicle SENSOR In-vehicle temperature is calculated as 25°C (77°F) and air conditioning system is controlled.
    B24A6-15 IN-Nissan Ariya Vehicle SENSOR

  • If a CAN communication error exists between the A/C amp., ECM, IPDM E/R, BCM and combination meter for 2 seconds or longer, air conditioning is controlled under the following conditions:

    A/C compressor : OFF

  • If a LIN communication error exists between the A/C amp. and A/C switch assembly for 30 seconds or longer, air conditioning is controlled under the following conditions:

    A/C compressor : ON
    Air outlet : AUTO
    Air inlet : AUTO
    Front blower fan speed : AUTO
    Set temperature : Setting before communication error occurs
