DIAGNOSIS SYSTEM (BCM)

The BCM records the following vehicle condition at the time a particular DTC is detected, and displays on
CONSULT.

NOTE:

*: Power supply position shifts to “LOCK” from “OFF”, when ignition switch is in the OFF position, selector lever is in the P position, and
any of the following conditions are met.

• Closing door

• Opening door

• Door is locked using door request switch

• Door is locked using Intelligent Key

The power supply position shifts to “ACC” when the push-button ignition switch (push switch) is pushed at “LOCK”.
