INSPECTION PROCEDURE

1. Select the Active Test, use the intelligent tester to generate a control command, and then check that the headlight assembly illuminates.
   
   

   Engine room No. 2 relay block:

   
   

   Item	Test Details	Diagnostic Note
   Light HEAD (High)	Headlight (High) ON / OFF	-

   OK:

   Headlight assembly illuminates.
   

1. Remove the FR CTRL-B fuse from the engine room No. 2 relay block.
   

2. Remove the H-LP UPR fuse from the engine room No. 2 junction block.
   

3. Measure the resistance of the fuses.
   

   Standard resistance:

   Below 1 Ω
   

1. Temporarily replace the headlight No. 1 bulb with a new or normally functioning one.
   

2. Check that the bulb illuminates.
   

   OK:

   Headlight No. 1 bulb illuminates.
   

1. Disconnect the 2E junction block connector.
   

2. Measure the voltage of the wire harness side connector.
   

   Standard voltage:

   Tester Connection	Specified Condition
   2E-2 - Body ground	10 to 14 V

1. Disconnect the 2G junction block connector.
   

2. Measure the resistance of the wire harness side connector.
   

   Standard resistance:

   Tester Connection	Specified Condition
   2G-13 - Body ground	Below 1 Ω
   2G-12 - Body ground	Below 1 Ω
