Pinpoint Tests

Normal Operation
When the high beams are off, voltage is routed from the high beam relay to the battery junction box (BJB) fuse 26 (15A) through circuit 15S-DA28 (GN/BK). Voltage is then routed to the headlamp switch through circuit 30-LD10 (RD). When the fog lamp switch is engaged, voltage is routed to the fog lamps through circuit 15S-LD9 (GN/BK).

Possible Causes
- Fuse
- Circuit 15S-DA28 (GN/BK) open
- Circuit 15S-LD9 (GN/BK) open
- Circuit 30-LD10 (RD) open
- High beam relay
