INSPECTION PROCEDURE

1. Check that the navigation display is normal.
   

   OK:

   The navigation display is normal.
   

   HINT:

   1. When trouble occurs in the navigation display, inspect the circuit between the television camera ECU and multi-display (Click here).
      
   2. When the navigation display is normal, inspect the circuit between the television camera ECU and television camera by following the steps below.
      

1. Disconnect the L64 ECU connector.
   

2. Disconnect the a8 camera connector.
   

3. Measure the resistance of the wire harness side connectors.
   

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   L64-20 (CB+) - a8-4 (CB+)	Always	Below 1 Ω
   L64-19 (CGND) - a8-3 (CGND)	Always	Below 1 Ω
   L64-40 (CV+) - a8-2 (CV+)	Always	Below 1 Ω
   L64-39 (CV-) - a8-1 (CV-)	Always	Below 1 Ω
   L64-20 (CB+) - Body ground	Always	10 kΩ or higher
   L64-19 (CGND) - Body ground	Always	10 kΩ or higher
   L64-39 (CV+) - Body ground	Always	10 kΩ or higher
   L64-39 (CV-) - Body ground	Always	10 kΩ or higher

1. Measure the voltage of the connector.
   

   Standard voltage:

   Tester Connection	Condition	Specified Condition
   a8-4 (CB+) - a8-3 (CGND)	Engine switch on (IG), shift lever in R position	Approx. 6 V
