  1. CHECK AIR CONDITIONING AMPLIFIER ASSEMBLY

    A015BHYE03

    1. Disconnect the E81 air conditioning amplifier assembly connector.

    2. Measure the resistance and voltage according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      E81-1 (IG+) - E81-14 (GND) G - W-B Ignition power supply Ignition switch ON 11 to 14 V
      Ignition switch off Below 1 V
      E81-21 (+B1) - E81-14 (GND) R - W-B Battery power source Always 11 to 14 V
      E81-14 (GND) - Body ground W-B - Body ground Ground Always Below 1 Ω

      • If the result is not as specified, there may be a malfunction on the wire harness side.

    3. Reconnect the E81 air conditioning amplifier assembly connector.

    4. Measure the voltage according to the value(s) in the table below.

      Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
      E81-38 (RDEF) - E81-14 (GND) G - W-B Defogger relay Ignition switch ON and defogger switch off 11 to 14 V
      Ignition switch ON and defogger switch on Below 1 V

      • If the result is not as specified, the air conditioning amplifier assembly or fuse may have a malfunction.

  2. CHECK AIR CONDITIONING CONTROL ASSEMBLY
