: CHECK THE REAR ENTERTAINMENT CONTROL PANEL RIGHT-HAND OUTPUTS

G240121t37 : CHECK THE CONT R1 OUTPUT FROM THE CONTROL PANEL
1. Disconnect the control panel electrical connector, RC03.
2. Turn the video/audio tester ON, and to the TEST position by holding in the TEST button while selecting PAL or NTSC. The blue and red LEDs will illuminate.
3. Make sure both screens are selected on the control panel.
4. Turn the ignition switch to the ON position.
5. Measure the voltage between RC03, pin 11 (probing INTO the control panel) and GROUND.

- Is the voltage 5 volts?

-> Yes

-> No
INSTALL a new control panel, TEST the system for normal operation.

G240121t38 : CHECK THE CONT R2 OUTPUT FROM THE CONTROL PANEL
1. Measure the voltage between RC03, pin 10 (probing INTO the control panel) and GROUND.

- Is the voltage 0 volts?

-> Yes

-> No
INSTALL a new control panel, TEST the system for normal operation.

G240121t39 : CHECK THE CONT R3 OUTPUT FROM THE CONTROL PANEL
1. Measure the voltage between RC03, pin 09 (probing INTO the control panel) and GROUND.

- Is the voltage 5 volts?

-> Yes

-> No
INSTALL a new control panel, TEST the system for normal operation.

G240121t40 : CHECK THE R1 CIRCUIT FROM RC03 TO TL86 FOR CONTINUITY
1. Disconnect the audio video selector electrical connector, TL86.
2. Measure the resistance between RC03, pin 11 (WU) and TL86, pin 11 (WU).

- Is the resistance greater than 5 ohms?

-> Yes
-> No

G240121t41 : CHECK THE R1 CIRCUIT FROM RC03 TO RC04 FOR CONTINUITY
1. Disconnect intermediate connector, RC04.
2. Measure the resistance between RC03, pin 11 (WU) and RC04, pin 11 (WU).

- Is the resistance greater than 5 ohms?

-> Yes
INSTALL a new harness between RC03 and RC04. TEST the system for normal operation.

-> No
INSTALL a new harness between RC03 and TL86. TEST the system for normal operation.

G240121t42 : CHECK THE R2 CIRCUIT FROM RC03 TO TL86 FOR CONTINUITY
1. Reconnect intermediate connector, RC04.
2. Measure the resistance between RC03, pin 10 (B) and TL86, pin 10 (B).

- Is the resistance greater than 5 ohms?

-> Yes
-> No

G240121t43 : CHECK THE R2 CIRCUIT FROM RC03 TO RC04 FOR CONTINUITY
1. Disconnect intermediate connector, RC04.
2. Measure the resistance between RC03, pin 10 (B) and RC04, pin 10 (B).

- Is the resistance greater than 5 ohms?

-> Yes
INSTALL a new harness between RC03 and RC04. TEST the system for normal operation.

-> No
INSTALL a new harness between RC03 and TL86. TEST the system for normal operation.

G240121t44 : CHECK THE R3 CIRCUIT FROM RC03 TO TL86 FOR CONTINUITY
1. Reconnect intermediate connector, RC04.
2. Measure the resistance between RC03, pin 09 (WB) and TL86, pin 09 (WB).

- Is the resistance greater than 5 ohms?

-> Yes

-> No
The AUX1 circuit checks out.

G240121t45 : CHECK THE R3 CIRCUIT FROM RC03 TO RC04 FOR CONTINUITY
1. Disconnect intermediate connector, RC04.
2. Measure the resistance between RC03, pin 09 (WB) and RC04, pin 09 (WB).

- Is the resistance greater than 5 ohms?

-> Yes
INSTALL a new harness between RC03 and RC04. TEST the system for normal operation.

-> No
INSTALL a new harness between RC03 and TL86. TEST the system for normal operation.
