1. Before testing the multiplex control system, troubleshoot the system using B-CAN System Diagnosis Test Mode A(see page 22-93).
2. Check the No. 10 (7.5 A) fuse in the under-dash fuse/relay box. If the fuse is blown, replace it and go to step 3.
3. Disconnect the under-dash fuse/relay box connectors E, F, R, and S. NOTE: All connector views are wire side of female terminals.
4. Inspect the connector and socket 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.

5. Reconnect the connector to the under-dash fuse/relay box, and do these input tests at the following connectors.
 If any test indicates a problem, find and correct the cause, then recheck the system.
 If all the input tests prove OK, the MICU must be faulty; replace the under-dash fuse/relay box.

NOTE: If both of the front and console accessory power
sockets do not work, check the No. 35 (7.5 A) fuse in the
under-dash fuse/relay box. 1. Remove the center panel.  With audio:– ’06-08 models (see page 23-80)
– ’09 model (see page 23-256)
 With navigation: – ’06-08 models (see page 23-155)
– ’09 model (see page 23-355)
2. Disconnect the 2P connector (A) from the front 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.
 IftheterminalslookOK,gotostep4.
4. Turn the ignition switch to ACC (I).
5. Measure the voltage between front accessory power socket 2P connector terminal No. 1 and body
ground. There should be battery voltage.
 If there is battery voltage, go to step 6.
 If there is no voltage, check for: – Blown No. 29 (15 A) fuse in the under-dash fuse/relay box.
– Faulty front accessory power socket relay.
– Poor ground (G 503).
– Anopeninthewire. 6. Check for continuity between front accessory
power socket 2P connector terminal No. 2 and body
ground. There should be continuity.
 If there is continuity, replace the power socket; go to step 7.
 If there is no continuity, check for: – Poor ground (G 502).
– Anopeninthewire.
7. Remove the socket (A).
8. Remove the housing (A) from the panel.
9. Install the front accessory power socket in the reverse order of removal.
