COMMON ITEM
COMMON ITEM : CONSULT Function (BCM - COMMON ITEM)INFOID:0000000009956271
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and a no-start condition.
APPLICATION ITEM
CONSULT performs the following functions via CAN communication with BCM.
SYSTEM APPLICATION
BCM can perform the following functions.
Direct Diagnostic Mode Description
Ecu Identification The BCM part number is displayed.
Self Diagnostic Result The BCM self diagnostic results are displayed.
Data Monitor The BCM input/output data is displayed in real time.
Active Test The BCM activates outputs to test components.
Work support The settings for BCM functions can be changed.
Configuration • The vehicle specification can be read and saved.
• The vehicle specification can be written when replacing BCM.

WELCOME LIGHT FUNCTION
WELCOME LIGHT FUNCTION : System DiagramINFOID:0000000009461786
WELCOME LIGHT FUNCTION : System DescriptionINFOID:0000000009461787
The welcome light function operates as per the following. When the Intelligent Key is within the outside key
antenna detection area, the BCM turns on interior room lamp
* and operates heart beat operation of the push-
button ignition switch.
*: Settings for map lamp, foot lamp, personal lamp, and puddle lamp are available.
OPERATION DESCRIPTION
• When the BCM detects that the Intelligent Key is within the outside key antenna detection area. BCM trans-
mits the request signal to the Intelli gent Key and check it is near the door.
• Intelligent Key receives the request signal and transmits the key ID signal to the BCM via remote keyless entry receiver.
• BCM receives the key ID signal and compares it with the registered key ID.
• BCM illuminates lamps that are set, when key ID verification is OK.
TIMER FUNCTION
BCM can operate welcome light function using the timer function for 9 days after key switch is turned OFF.
The timer function resets when the engine is started
*.Operating period of timer function may differ depending
on battery size.
