  2. 1 2 AWHT*1BRN*2BLKWire side offemale terminals

    *1: Front upper accessory power socket
    *2: Front lower accessory power socket

  3. Inspect the connector terminals to be sure they are all making good contact.

    • If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.

    • If the terminals look OK, go to step 5.

  5. Choose the appropriate test:

    • Front upper accessory power socket, go to step 7.

    • Front lower accessory power socket, go to step 10.

  6. Measure the voltage between passenger's under-dash fuse/relay box connector E (42P) terminal No. 8 and body ground. There should be less than 0.2 V.

    • If there is less than 0.2 V, go to step 8.

    • If there is more than 0.2 V, check for:

      • An open or high resistance in the ground wire between passenger's under-dash fuse/relay box connector E (42P) terminal No. 8 and ground (G405).

      • Poor ground (G405).

  7. Measure the voltage between front upper accessory power socket 2P connector terminal No. 2 and body ground. There should be battery voltage.

    • If there is battery voltage, go to step 9.

    • If there is no voltage, check for:

      • Blown No. D27 (15 A) fuse in the passenger's under-dash fuse/relay box.

      • Faulty front upper accessory power socket relay.

      • Faulty passenger's under-dash fuse/relay box.

  8. Check for continuity between front upper accessory power socket 2P   connector terminal No. 1   and body ground. There should be continuity.

    • If there is continuity, replace the power socket; then go to step 13.

    • If there is no continuity, check for:

      • An open or high resistance in the ground wire between front upper accessory power socket 2P connector terminal No. 1 and ground (G403).

      • Poor ground (G403).

  9. Measure the voltage between passenger's under-dash fuse/relay box connector E (42P) terminal No. 8 and body ground. There should be less than 0.2 V.

    • If there is less than 0.2 V, go to step 11.

    • If there is more than 0.2 V, check for:

      • An open or high resistance in the ground wire between passenger's under-dash fuse/relay box connector E (42P) terminal No. 8 and ground (G405).

      • Poor ground (G405).

  10. Measure the voltage between front lower accessory power socket 2P connector terminal No. 2 and body ground. There should be battery voltage.

    • If there is battery voltage, go to step 12.

    • If there is no voltage, check for:

      • Blown No. D15 (15 A) fuse in the passenger's under-dash fuse/relay box.

      • Faulty front lower accessory power socket relay.

      • Faulty passenger's under-dash fuse/relay box.

      • An open in the wire between front lower accessory power socket terminal No. 2 and passenger's under-dash fuse/relay box connector E (42P) terminal No. 11.

  11. Check for continuity between front lower accessory power socket 2P   connector terminal No. 1   and body ground. There should be continuity.

    • If there is continuity, replace the power socket; go to step 13.

    • If there is no continuity, check for:

      • An open or high resistance in the ground wire between front lower accessory power socket 2P connector terminal No. 1 and ground (G403).

      • Poor ground (G403).


  1. Remove the housing (A) from the panel.

    NOTE: The front upper accessory power socket is shown; the front lower accessory power socket is similar.

  2. A
  3. Install the power socket in the reverse order of removal.
