: CHECK THE REAR ENTERTAINMENT CONTROL PANEL LEFT-HAND OUTPUTS

G240121t28 : CHECK THE CONT L1 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 15 (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.

G240121t29 : CHECK THE CONT L2 OUTPUT FROM THE CONTROL PANEL
1. Measure the voltage between RC03, pin 14 (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.

G240121t30 : CHECK THE CONT L3 OUTPUT FROM THE CONTROL PANEL
1. Measure the voltage between RC03, pin 19 (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.

G240121t31 : CHECK THE L1 CIRCUIT FROM RC03 TO TL86 FOR CONTINUITY
1. Disconnect the audio video selector electrical connector, TL86.
2. Measure the resistance between RC03, pin 15 (WR) and TL86, pin 15 (WR).

- Is the resistance greater than 5 ohms?

-> Yes
-> No

G240121t32 : CHECK THE L1 CIRCUIT FROM RC03 TO RC04 FOR CONTINUITY
1. Disconnect intermediate connector, RC04.
2. Measure the resistance between RC03, pin 15 (WR) and RC04, pin 15 (WR).

- 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.

G240121t33 : CHECK THE L2 CIRCUIT FROM RC03 TO TL86 FOR CONTINUITY
1. Reconnect intermediate connector, RC04.
2. Measure the resistance between RC03, pin 14 (B) and TL86, pin 14 (B).

- Is the resistance greater than 5 ohms?

-> Yes
-> No

G240121t34 : CHECK THE L2 CIRCUIT FROM RC03 TO RC04 FOR CONTINUITY
1. Disconnect intermediate connector, RC04.
2. Measure the resistance between RC03, pin 14 (B) and RC04, pin 14 (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.

G240121t35 : CHECK THE L3 CIRCUIT FROM RC03 TO TL86 FOR CONTINUITY
1. Reconnect intermediate connector, RC04.
2. Measure the resistance between RC03, pin 19 (YG) and TL86, pin 19 (YG).

- Is the resistance greater than 5 ohms?

-> Yes

-> No
The AUX1 circuit checks out.

G240121t36 : CHECK THE L3 CIRCUIT FROM RC03 TO RC04 FOR CONTINUITY
1. Disconnect intermediate connector, RC04.
2. Measure the resistance between RC03, pin 19 (YG) and RC04, pin 19 (YG).

- 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.
