DTC CONFIRMATION PROCEDURE


1. PERFORM DTC CONFIRMATION PROCEDURE

1.Make the conditions that BCM enters in the low power consumption mode (BCM sleep condition).
With Intelligent Key System.
2.Turn ignition switch ON.
3.Check DTC in "Self Diagnostic Result" mode of "BCM" using CONSULT.
Is DTC detected?
YES- Go to .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK FUSE
