Inspect the C/U IG1 15A fuse.
• If the fuse is burnt out:
-
? Refer to the wiring diagram and verify whether or not there is a common connector between C/U IG1 15A fuse and blind spot monitoring (BSM) control module terminal I.
If there is a common connector:
-
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
• Repair or replace the malfunctioning part.
If there is no common connector:
-
• Repair or replace the wiring harness which has a short to ground.
• Replace the fuse.
• If the fuse is damaged:
-
? Replace the fuse.
• If the fuse is normal:
-
? Refer to the wiring diagram and verify whether or not there is a common connector between IG1 relay terminal C and blind spot monitoring (BSM) control module terminal I.
If there is a common connector:
-
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
• Repair or replace the malfunctioning part.
If there is no common connector:
-
• Repair or replace the wiring harness which has an open circuit.
Go to the next step.
