  3. CHECK FUSE (AM2)


    1. A01KRKEC01
      *1 No. 1 Engine Room Relay Block and No.1 Junction Block Assembly
      *2 AM2 Fuse

      Remove the AM2 fuse from the No. 1 engine room relay block and No.1 junction block assembly.

    2. Check if there is an open circuit in the AM2 fuse in the No. 1 engine room relay block and No.1 junction block assembly.

      OK
      There is no open circuit in the AM2 fuse.

    3. Install the AM2 fuse.

    REPLACE FUSE (AM2)

    OK

  4. CHECK HARNESS AND CONNECTOR (AM2 FUSE - BATTERY TERMINAL)


    1. A01KSDBC01
      *1 No. 1 Engine Room Relay Block and No.1 Junction Block Assembly
      *2 AM2 Fuse

      Remove the AM2 fuse from the No. 1 engine room relay block and No.1 junction block assembly.

    2. Disconnect the cable from the negative (-) auxiliary battery terminal.

    3. Disconnect the cable from the positive (+) auxiliary battery terminal.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - Auxiliary battery positive (+) cable Power switch off Below 1 Ω
      1 - Body ground Power switch off 10 kΩ or higher

    5. Connect the cable to the positive (+) auxiliary battery terminal.

    6. Connect the cable to the negative (-) auxiliary battery terminal.

    7. Install the AM2 fuse.
