Test D: One Low Beam Headlamp Is Inoperative

PINPOINT TEST D: ONE LOW BEAM HEADLAMP IS INOPERATIVE

D1-D2:

D2-D3:

Normal Operation
When the low beam relay is energized, voltage is routed through circuits 15S-DC16 (GN/BU) and 15S-DC17 (GN/BU) to the battery junction box (BJB) fuse 16 (10A) and fuse 17 (10A), respectively. The voltage is then routed through circuits 15S-LE16 (GN/OG) and 15S-LE23 (GN/WH) to the LH and RH headlamps, respectively. Ground is provided through circuits 31-LE31 (BK) and 31-LE30 (BK) to the LH and RH headlamps, respectively.

Possible Causes
- Fuse
- Circuit 15S-DC16 (GN/BU) open
- Circuit 15S-DC17 (GN/BU) open
- Circuit 15S-LE16 (GN/OG) open
- Circuit 15S-LE23 (GN/WH) open
- Circuit 31-LE31 (BK) open
- Circuit 31-LE30 (BK) open
- Headlamp assembly
