INSPECTION PROCEDURE

NOTICE:
Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Navigation System (Click here).
1.CHECK VEHICLE SIGNAL (OPERATION CHECK)


    Land Cruiser. Urj200, 202 Grj200 Vdj200

  1. Enter the "Vehicle Signal Check Mode" screen. [Refer to check Vehicle Signal in Operation Check (Click here)].

  1. 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 multi-media module receiver assembly connector.

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

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    F77-57 (REV) - Body ground
    		Engine switch on (IG), shift lever in R
    		7.5 to 14 V
    F77-57 (REV) - Body ground
    		Engine switch on (IG), shift lever not in R
    		Below 1 V

3.CHECK HARNESS AND CONNECTOR (MULTI-MEDIA MODULE RECEIVER ASSEMBLY - PARK/NEUTRAL POSITION SWITCH ASSEMBLY)

  1. Disconnect the F77 multi-media module receiver assembly connector.

  1. Disconnect the C24 park/neutral position switch assembly connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    F77-57 (REV) - C24-2 (RL)
    		Always
    		Below 1 Ω
    F77-57 (REV) - Body ground
    		Always
    		10 kΩ or higher
