HIGH FLASHER OPERATION
BCM detects the turn signal lamp circuit status by the current value.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.
DTC Inspection Priority ChartINFOID:0000000003940048
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
