Description
WORK SUPPORT Supports inspections and adjustments. Commands are transmitted to the BCM for setting the sta-
tus suitable for required operation, input/output signals are received from the BCM and received
date is displayed.
DATA MONITOR Displays BCM input/output data in real time. ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to them.
SELF DIAGNOSTIC RESULT Displays BCM self-diagnosis results.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read. ECU IDENTIFICATION BCM part number can be read.CONFIGURATION Performs BCM configuration read/write functions.
