INSPECT AUXILIARY JACK/USB PORT/SD CARD SLOT HUB CIRCUIT FOR SHORT TO GROUND
• Verify that the auxiliary jack/USB port/SD card slot hub connector and the connectivity master unit (CMU) connector are disconnected.
• Inspect for continuity between auxiliary jack/USB port/SD card slot hub terminal 2C (wiring harness-side) and body ground.
• Is there continuity?
|
Yes
|
Refer to the wiring diagram and verify if there is a common connector between connectivity master unit (CMU) terminal 4C and auxiliary jack/USB port/SD card slot hub terminal 2C.
If there is a common connector:
• Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to ground to determine the malfunctioning location.
• Repair or replace the malfunctioning location.
If there is no common connector:
• Repair or replace the wiring harness which is shorted to ground.
Go to Step 7.

INSPECT AUXILIARY JACK/USB PORT/SD CARD SLOT HUB CIRCUIT FOR SHORT TO POWER SUPPLY
• Verify that the auxiliary jack/USB port/SD card slot hub connector and the connectivity master unit (CMU) connector are disconnected.
• Reconnect the negative battery cable.
• Switch the ignition ON (engine off or on).
• Measure the voltage at the auxiliary jack/USB port/SD card slot hub terminal 2C (wiring harness-side).
• Is the voltage 0 V?
|
Yes
|
Go to the next step.
|
|
No
|
Refer to the wiring diagram and verify if there is a common connector between auxiliary jack/USB port/SD card slot hub terminal 2C and connectivity master unit (CMU) terminal 4C.
If there is a common connector:
• Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to power supply to determine the malfunctioning location.
• Repair or replace the malfunctioning location.
If there is no common connector:
• Repair or replace the wiring harness which is shorted to the power supply.
Go to Step 7.

5
|
INSPECT AUXILIARY JACK/USB PORT/SD CARD SLOT HUB CIRCUIT FOR OPEN CIRCUIT
• Switch the ignition off.
• Disconnect the negative battery cable.
• Verify that the auxiliary jack/USB port/SD card slot hub connector and the connectivity master unit (CMU) connector are disconnected.
• Inspect for continuity in the wiring harness between connectivity master unit (CMU) terminal 4C (wiring harness-side) and auxiliary jack/USB port/SD card slot hub terminal 2C (wiring harness-side).
• Is there continuity?
|
Yes
|
Go to the next step.
|
|
No
|
Refer to the wiring diagram and verify if there is a common connector between connectivity master unit (CMU) terminal 4C and auxiliary jack/USB port/SD card slot hub terminal 2C.
If there is a common connector:
• Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for an open circuit to determine the malfunctioning location.
• Repair or replace the malfunctioning location.
If there is no common connector:
• Repair or replace the wiring harness which has an open circuit.
Go to Step 7.
