WIRING DIAGRAM

INSPECTION PROCEDURE

1. Enter the "Function Check/Setting I" mode and select "Vehicle Signal" (HILUX_TGN26 RM0000043X901QX.html).
   

2. Check that the display changes between ON and OFF according to the shift lever position.
   

   OK:

   Shift Lever Position	Display
   R	ON
   Except R	OFF

   HINT:

   This display is updated once per second. As a result, it is normal for the display to lag behind the actual shift lever position.

1. Disconnect the G127 radio and display receiver assembly connector.
   

2. Measure the voltage according to the value(s) in the table below.
   

   Standard Voltage:

   Tester Connection	Condition	Specified Condition
   G127-2 (REV) - Body ground	Ignition switch ON, shift lever in R	7.5 to 14 V
   G127-2 (REV) - Body ground	Ignition switch ON, shift lever not in R	Below 1 V
