PINPOINT TEST G240121p12 : CHECK G240121t108 : CHECK FOR BATTERY VOLTAGE AT THE SCREEN 1. Disconnect the left-hand screen electrical connector, VL01. 2. Turn the ignition switch to the ON position. 3. Measure the voltage between VL01, pin 18 (OY) and GROUND. •
Is the voltage greater than 10 volts? -> Yes GO to Pinpoint Test G240121t113.
-> No GO to Pinpoint Test G240121t109.
G240121t109 : CHECK THE CIRCUIT BETWEEN VL01 AND TL85 FOR 1. Disconnect the audio video selector module electrical connector, TL85. 2. Measure the resistance between VL01, pin 18 (OY) and TL85, pin 18 (OY). •
Is the resistance greater than 5 ohms? -> Yes GO to Pinpoint Test G240121t110.
-> No INSTALL a new audio video selector module, Video System Module TEST the system for normal operation. G240121t110 : CHECK THE CIRCUIT BETWEEN VL01 AND VL02 FOR 1. Disconnect intermediate connector, VL02. 2. Measure the resistance between VL01, pin 18 (OY) and VL02, pin 18 (OY). •
Is the resistance greater than 5 ohms? -> Yes INSTALL a new harness between VL01 and VL02. TEST the system for normal operation. |
