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 sound produces?

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.
(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION)

•  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 9.

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 9.

4

VERIFY IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN TUNER AMP UNIT (TAU) AND DVD/CD PLAYER

•  Verify that the DVD/CD player and the amp unit (TAU) connector are disconnected.

•  Inspect the wiring harness for continuity between the following terminals (vehicle wiring harness side).

―  Tuner and amp unit (TAU) terminal 1M and DVD/CD player terminal L

―  Tuner and amp unit (TAU) terminal 1N and DVD/CD player terminal N
