WIRING DIAGRAM

INSPECTION PROCEDURE

1. Disconnect the headlight connector on the headlight beam level control motor side and headlight beam level control ECU connector.
   

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

   Standard resistance:

   
   

   LH side

   Tester Connection	Condition	Specified Condition
   A30-29 (LL1+) - B11-15 (LL1+)	Always	Below 1 Ω
   A30-30 (LL1-) - B11-14 (LL1-)	Always	Below 1 Ω
   A30-31 (LL2+) - B11-13 (LL2+)	Always	Below 1 Ω
   A30-32 (LL2-) - B11-12 (LL2-)	Always	Below 1 Ω
   A30-29 (LL1+) or B11-15 (LL1+) - Body ground	Always	10 kΩ or higher
   A30-30 (LL1-) or B11-14 (LL1-) - Body ground	Always	10 kΩ or higher
   A30-31 (LL2+) or B11-13 (LL2+) - Body ground	Always	10 kΩ or higher
   A30-32 (LL2-) or B11-12 (LL2-) - Body ground	Always	10 kΩ or higher

   
   

   RH side

   Tester Connection	Condition	Specified Condition
   A30-13 (LR1+) - B2-15 (LR1+)	Always	Below 1 Ω
   A30-14 (LR1-) - B2-14 (LR1-)	Always	Below 1 Ω
   A30-15 (LR2+) - B2-13 (LR2+)	Always	Below 1 Ω
   A30-16 (LR2-) - B2-12 (LR2-)	Always	Below 1 Ω
   A30-13 (LR1+) or B2-15 (LR1+) - Body ground	Always	10 kΩ or higher
   A30-14 (LR1-) or B2-14 (LR1-) - Body ground	Always	10 kΩ or higher
   A30-15 (LR2+) or B2-13 (LR2+) - Body ground	Always	10 kΩ or higher
   A30-16 (LR2-) or B2-12 (LR2-) - Body ground	Always	10 kΩ or higher

1. Measure the resistance of the motor.
   

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   1 - 2	Always	5.8 to 12.5 Ω
   3 - 4	Always	5.8 to 12.5 Ω

   HINT:

   Measure the resistance after the headlight has cooled.
