This circuit provides power to operate the blind spot monitor sensor.
w/o Stop and Start system:
Inspect the fuses for circuits related to this system before performing the following procedure.
w/ Stop and Start system:
The blind spot monitor system troubleshooting procedure is based on the premise that the stop and start system is operating normally. Check the stop and start system first before troubleshooting the blind spot monitor system.
