Diagnostic Procedure

Step

Inspection

Action

1
DETERMINE IF MALFUNCTION CAUSE IS DVD
•  After obtaining the customer’s consent, insert a DVD with the correct region code and image file.
•  Is DVD image output?
Yes
System is normal. Explain to the customer that the DVD cannot be played for any one of the following reasons.
•  Dirt or scratches on DVD
•  Incorrect region code
•  Image file not incompatible
No
Go to the next step.
2
INSPECT DVD/CD PLAYER CONNECTOR CONDITION
•  Disconnect the negative battery cable.
•  Disconnect the DVD/CD player connector.
•  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 8.
3
INSPECT CONNECTIVITY MASTER UNIT (CMU) CONNECTOR CONDITION
•  Disconnect the connectivity master unit (CMU) connector.
•  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 8.
4
VERIFY IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN CONNECTIVITY MASTER UNIT (CMU) AND DVD/CD PLAYER
•  Verify that the DVD/CD player and the connectivity master unit (CMU) connector are disconnected.
•  Inspect the wiring harness for continuity between the following terminals (vehicle wiring harness side).
―  Connectivity master unit (CMU) terminal 1G and DVD/CD player terminal U
―  Connectivity master unit (CMU) terminal 1H and DVD/CD player terminal V
•  Is there continuity?
Yes
Go to the next step.
No
•  Refer to the wiring diagram and verify if there is a common connector between the following terminals.
―  Connectivity master unit (CMU) terminal 1G and DVD/CD player terminal U
―  Connectivity master unit (CMU) terminal 1H and DVD/CD player terminal V
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 8.
5
VERIFY IF MALFUNCTION CAUSE IS SHORT CIRCUIT TO GROUND IN WIRING HARNESS BETWEEN CONNECTIVITY MASTER UNIT (CMU) AND DVD/CD PLAYER
•  Verify that the DVD/CD player and the connectivity master unit (CMU) connector are disconnected.
•  Inspect for continuity between the following terminals (vehicle wiring harness side) and body ground.
―  DVD/CD player terminal U
―  DVD/CD player terminal V
•  Is there continuity?
Yes
•  Refer to the wiring diagram and verify if there is a common connector between the following terminals.
―  Connectivity master unit (CMU) terminal 1G and DVD/CD player terminal U
―  Connectivity master unit (CMU) terminal 1H and DVD/CD player terminal V
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 8.
No
Go to the next step.
6
VERIFY IF MALFUNCTION CAUSE IS SHORT CIRCUIT TO POWER SUPPLY IN WIRING HARNESS BETWEEN CONNECTIVITY MASTER UNIT (CMU) AND DVD/CD PLAYER
•  Verify that the DVD/CD player and the connectivity master unit (CMU) connector are disconnected.
•  Reconnect the negative battery cable.
•  Switch the ignition to ACC or ON (engine off or on).
•  Measure the voltage at the following terminals (vehicle wiring harness side).
―  DVD/CD player terminal U
―  DVD/CD player terminal V
•  Is the voltage B+?
Yes
•  Refer to the wiring diagram and verify if there is a common connector between the following terminals.
―  Connectivity master unit (CMU) terminal 1G and DVD/CD player terminal U
―  Connectivity master unit (CMU) terminal 1H and DVD/CD player terminal V
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 8.
No
Go to the next step.
7
VERIFY IS MALFUNCTION CAUSE IS DVD/CD PLAYER
•  Switch the ignition off.
•  Disconnect the negative battery cable.
•  Replace the DVD/CD player.
•  Connect all the connectors.
•  Reconnect the negative battery cable.
•  Switch the ignition to ACC or ON (engine off or on).
•  Insert the DVD when the malfunction occurred.
•  Is DVD image output?
Yes
Troubleshooting completed. (Explain the contents of the servicing to the customer.)
No
Replace the connectivity master unit (CMU), then go to the next step.
8
VERIFY IF MALFUNCTION CAUSE IS CORRECTED
•  Switch the ignition to ACC or ON (engine off or on).
•  Insert the DVD when the malfunction occurred.
•  Is DVD image output?
Yes
Troubleshooting completed. (Explain the contents of the servicing to the customer.)
No
Verify the malfunction symptom in the symptom troubleshooting chart and perform the other applicable malfunction diagnosis.
