D4-D6:
Normal Operation
The central junction box (CJB) supplies voltage to the high beams. The LH high beam receives voltage through circuit 29S-LE15 (OG/BK). Ground for the LH high beam is provided through circuit 31S-LE15 (BK/GN). The RH high beam receives voltage through circuit 29S-LE22 (OG/GN). Ground for the RH high beam is provided through circuit 31S-LE22 (BK/RD). The front electronic module (FEM) controls the ground for both high beam headlamps.
Possible Causes
- Fuse
- Circuit 29S-LE15 (OG/BK) (LH headlamp) open
- Circuit 29S-LE22 (OG/GN) (RH headlamp) open
- Circuit 31S-LE15 (BK/GN) (LH headlamp) open or short to voltage
- Circuit 31S-LE22 (BK/RD) (RH headlamp) open or short to voltage
- FEM
