Cargo Area Accessory Power Socket Test/Replacement

Cargo Area Accessory Power Socket Test/Replacement

Rear Socket

NOTE: Before troubleshooting the rear accessory power socket, perform the multiplex integrated control system troubleshooting using B-CAN System Diagnosis Test Mode A Troubleshooting - B-CAN System Diagnosis Test Mode A.

1. Remove the tool box cover.

2. Disconnect the 2P connector (A) from the accessory power socket (B).





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 4.

4. Turn the ignition switch to ACCESSORY (I).

5. Measure the voltage between MICU-rear junction box connector C (6P) No. 1 and body ground. There should be less than 0.2 V.

- If there is less than 0.2 V, go to step 6.
- If there is more than 0.2 V, check for:
- An open or high resistance in the wire between MICU-rear junction box connector C (6P) terminal No. 1 and body ground (G652).
- Poor ground (G652) or an open in the ground wire.

6. Measure the voltage between cargo area accessory power socket 2P connector terminal No. 1 and body ground. There should be battery voltage.

- If there is battery voltage, go to step 7.
- If there is no voltage, check for:
- A blown No. 12 (15 A) fuse in the driver's under-dash fuse/relay box.
- A faulty cargo area accessory power socket relay.
- An open or high resistance in the wire between MICU-rear junction box connector E (8P) terminal No. 4 and cargo area accessory power socket 2P connector terminal No. 1.
- An open in the wire between MICU-rear junction box connector B (7P) terminal No. 2 and driver's under-dash fuse/relay box connector H (14P) terminal No. 4.

7. Check for continuity between cargo area accessory power socket 2P connector terminal No. 2 and body ground. There should be continuity.

- If there is continuity, go to step 8.
- If there is no continuity, check for:
- Poor ground (G702) or an open in the ground wire.
- An open in the wire between cargo area accessory power socket 2P connector terminal No. 2 and body ground (G702).

8. Remove the housing (A), cover (B) and socket (C).





9. Install the power socket in the reverse order of removal.
