VERTICAL SYNCHRONIZING (VP) SIGNAL CIRCUIT

Description

INFOID:0000000006246496

In composite image (AUX image, camera image), transmit the vertical synchronizing (VP) signal and horizon-

tal synchronizing (HP) signal from display unit to AV control unit so as to synchronize the RGB images dis-

played with AV control unit such as the image quality adjusting menu, etc.

Diagnosis Procedure

INFOID:0000000006246497

Regarding Wiring Diagram information, refer to 

AV-94, "Wiring Diagram"

.

1. Turn ignition switch OFF.

2. Disconnect display unit connector M93 and AV control unit con-

nector M133.

3. Check continuity between display unit harness connector M93

(A) terminal 20 and AV control unit harness connector M133 (B)

terminal 57.

4. Check continuity between display unit harness connector M93

(A) terminal 20 and ground.

Are continuity results as specified?

YES

>> GO TO 2

NO

>> Repair harness or connector.

2.

CHECK VERTICAL SYNCHRONIZING (VP) SIGNAL

1. Connect display unit connector M93 and AV control unit connec-

tor M133.

2. Turn ignition switch ON.

3. Check signal between display unit harness connector M93 ter-

minal 20 and ground.

Are voltage readings as specified?

YES

>> Replace AV control unit. Refer to 

AV-113, "Removal and Installation"

.

NO

>> Replace display unit. Refer to 

AV-115, "Removal and Installation"
