DIAGNOSIS SYSTEM (BCM)
COMMON ITEM
COMMON ITEM : CONSULT Function (BCM - COMMON ITEM)INFOID:0000000009941192
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”, potentiall y causing a discharged 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.
CAN Diag Support Mntr The result of transmit/receive diagnosis of CAN communication is displayed.
