Circuit/System Verification
1. Ignition ON, vehicle in Park. Operate the DVD entertainment system using several known good DVD disks.
⇒ | If the radio does not display the DVD, replace the radio. |
2. RSE ON and observe the rear DVD screen. Verify the rear video display is operational.
⇒ | If the rear video display turns ON, but is blank, or the video is poor quality, refer to circuit testing. |
Circuit/System Testing
- Ignition OFF, disconnect the rear video display harness connector.
- Ignition ON, DVD in radio playing, test for less than one volt on the DVD video drain wire terminal 12.
⇒ | If greater then specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the radio. |
- Test for.2 to.8 volts D/C on the DVD video signal circuit terminal 13. Voltage will fluctuate while a movie is playing.
⇒ | If the voltage is greater then the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the radio. |
⇒ | If the voltage is less then the specified range, test the circuit for an open/high resistance. If the circuit tests normal, replace the radio. |
