Code B1636 Chrysler Description

The Body Control Module (BCM) receives a communication network message from the Steering Column Control Module (SCCM) requesting high beam lamp illumination. When this message is received, the BCM provides a Pulse Width Modulated (PWM) voltage output through the high beam driver circuit which connects to the High Beam Lamp. A common ground circuit is used for the Low and High Beam Lamps. The BCM sets the OBDII code when it detects a low condition on the Right High Beam Driver circuit.
