Body Control Module PROGRAM PROCESS
The BCM will self-learn the LED turn signals by activating the
Hazards after LED installation. Activate the Hazard Warning
Lamps (four-way flashers). See operator's manual or service
manual. The BCM ignores the first 8 cycles of the Hazards.
The BCM learns during the next 8 Hazards. The BCM is
updated after 16 cycles.
