DTC B2417, DRL Control Module Circuit (Short To Ground Or Open): Notes
BCM interfaces with Daytime Running Light (DRL) control module to allow BCM to determine current ambient light operation mode. BCM uses class 2 serial data line to communicate this information to Instrument Panel Cluster (IPC). BCM uses information from circuit No. 1970 (Pink/White wire) to energize headlights.
DTC B2417 will set when BCM detects a short to ground or open in circuit No. 1970 (Pink/White wire) when ignition switch is turned from START to RUN position. No driver warning message will be displayed.
When ignition switch is turned from OFF to RUN position, a current DTC is always cleared. If conditions for malfunction is still present, DTC will reset as a current DTC. If conditions for malfunction no longer exist, history DTC will clear after 100 consecutive ignition cycles. DTC B2417 will also clear when conditions no longer exist or scan tool is used to clear codes.
