DTC PZ2473, High Beam Output Fault: Notes

High beams are commanded by PZM through an output to LO/HI beam control relay. When headlight relay is energized, LO/HI beam control relay provides power source to low beams or high beams. DTC PZ2473 will set when commanded state of high beams does not match feedback state. When DTC PZ2473 is set, PZM will continue to command state requested until IPC revokes request. DTC PZ2473 will clear when commanded state matches feedback state.
