    No. B19 (7.5 A)
    Location Under-dash fuse/relay box

    Is each fuse OK?

    YES 

    Go to step 3.

    NO 

    Replace the fuse. If the fuse blows again, repair a short to ground in the No. A2-2 (60 A), No. B27 (20 A), and/or No. B19 (7.5 A) fuse circuit(s).

  3. 3. Front accessory power socket relay check:

    - 1. Remove the front accessory power socket relay from the under-dash fuse/relay box, and test it .

    Is the relay OK?

    YES 

    Go to step 4.

    NO 

    Replace the front accessory power socket relay, then recheck.

  4. 4. Open wire check (+B F/BOX MAIN line) 1:

    - 1. Measure the voltage between test points 1 and 2.

    Test point 1 Under-dash fuse/relay box connector D (32P) No. 2
    Test point 2 Body ground

    Is there battery voltage?

    YES 

    Go to step 5.

    NO 

    Repair an open or high resistance in the wire.

  5. 5. Open wire check (+B F/BOX MAIN line) 2:

    - 1. Measure the voltage between test points 1 and 2.

    Is there battery voltage?

    YES 

    Go to step 6.

    NO 

    Repair an open or high resistance in the wire.

  6. 6. Determine possible failure area (front accessory power socket relay switch side circuit, front accessory power socket relay coil side circuit):

    - 1. Connect terminals A and B with a jumper wire.

    Terminal A Front accessory power socket relay 4P socket No. 1
    Terminal B Front accessory power socket relay 4P socket No. 2

    Does the front accessory power socket work?

    YES 

    Go to step 7.

    NO 

    Go to step 9.

  7. 7. Open wire check (ACC MAIN line) 1:

    - 1. Turn the vehicle to the ACCESSORY mode.

    - 2. Measure the voltage between test points 1 and 2.

    Test condition Vehicle ACCESSORY mode Front accessory power socket: disconnected Front accessory power socket 4P socket No. 1 and No. 2: jumped
    Test point 1 Under-dash fuse/relay box connector A (5P) No. 5
    Test point 2 Body ground

    Is there battery voltage?

    YES 

    Go to step 8.

    NO 

    Repair an open or high resistance in the wire.

  8. 8. Open wire check (ACC MAIN line) 2:

    - 1. Measure the voltage between test points 1 and 2.

    Test condition Vehicle ACCESSORY mode Front accessory power socket relay: disconnected Front accessory power socket relay 4P socket No. 1 and No. 2: jumped
