STEP 1. Check the multivision display operation.
Check if the multivision display work normally and the sound is
output.
Q: Is the check result normal?
YES : Go to Step 2.
NO : Troubleshoot the MMCS (Refer to
STEP 2. Check the multivision display operation.
Display the A/V Mode screen, and check that the "USB/iPod"
item is displayed.
Q: Is the check result normal?
YES : Go to Step 8.
NO : Go to Step 3.
STEP 3. Check USB box connector C-135 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: IS hands USB box connector C-135 in good condition?
YES : Go to Step 4.
NO : Repair the defective connector.
STEP 4. Check the power supply circuit to the USB box.
Measure the voltage at USB box connector C-135.
(1) Disconnect USB box connector C-135, and measure the
voltage available at the wiring harness side of the
connector.
(2) Measure the voltage between terminal 1 and ground.
OK: The voltage should measure approximately 12
volts (battery positive voltage).
Q: Is the measured voltage approximately 12 volts (battery
positive voltage)?
YES : Go to Step 6.
NO : Go to Step 5.

STEP 5. Check the wiring harness between USB box
connector C-135 (terminal 1) and fusible link (36).
• Check the power supply lines (battery power supply) for
open circuit and short circuit.
NOTE: Also check ETACS-ECU connector C-307, C-317 for
loose, corroded, or damaged terminals, or terminals pushed
back in the connector. If ETACS-ECU connector C-307, C-317
is damaged, repair or replace the connector as described in
GROUP 00E, Harness Connector Inspection
Q: Is the wiring harness between hands-free module
connector C-135 (terminal 1) and fusible link (36) in
good condition?
YES : The trouble can be an intermittent malfunction (Refer
to GROUP 00, How to use
Troubleshooting/inspection Service Points, How to
Cope with Intermittent Malfunction
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary.
STEP 6. Check the ground circuit to the USB box. Measure
the resistance at hands USB box connector C-135.
(1) Disconnect USB box connector C-135, and measure at the
wiring harness side.
(2) Measure resistance between terminal 17 and ground.
OK: The resistance should be 2 ohm or less.
Q: Is the measured resistance 2 ohms or less?
YES : Go to Step 8.
NO : Go to Step 7.
STEP 7. Check the wiring harness between USB box
connector C-135 (terminal 17) and ground.
• Check the body ground wires for open circuit.
Q: Is the wiring harness between USB box connector C-135
(terminal 17) and ground in good condition?
YES : The trouble can be an intermittent malfunction (Refer
to GROUP 00, How to use
Troubleshooting/inspection Service Points, How to
Cope with Intermittent Malfunction
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary.
