Fail-safe

FAIL-SAFE FUNCTION

  • 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 : Setting before communication error occurs
    Air outlet : Setting before communication error occurs
    Air inlet : Setting before communication error occurs
    Front blower fan speed : Setting before communication error occurs
