Flash-to-Pass System Operation

The Flash-to-Pass feature allows the driver to signal the driver of another vehicle his intention to pass. This is achieved by pulling the lever toward the driver, which will cause the high beam operation to illuminate until the lever is released. The operation of the headlamps with the turn signal/headlamp switch in flash-to-pass mode is similar to the operation of the switch in the high beam mode, as mentioned in the previous paragraph, with the exception that 2 ground paths are provided to the DRL control module. One path is through junction block 1, the turn signal/headlamp switch and SP250 to G203, which simulates the operation of the light switch in the head position. The other is through the dimmer switch and SP250 to G203.
