Flash-To-Pass

The flash-to-pass switch is permanently grounded via CKT 350 (BLK) to G200. When the headlamp dimmer switch is pulled toward driver, the flash-to-pass switch in the headlamp dimmer switch closes. The DIM Flash-To-Pass input is grounded via CKT 1484 (PNK/BLK). In response to this input, the DIM supplies ground via CKT 1969 (BLK/WHT) to the HDLP HI BM relay coil. The HDLP HI BM relay has battery positive voltage (B+) as described above. The relay is energized closing the switch contacts. The high beam headlamps are supplied battery positive voltage (B+) as described above. If the low beam headlamps are already on, the will remain on during flash-to-pass. The high beam headlamps will only remain on as long as the switch is held.
