NOTE
DATA MONITOR Displays BCM input data in real time.
ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to them.
BCMSELF-DIAG RESULTS BCM performs self-diagnosis of CAN communication.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ALL SIGNALS Monitors all the signals.
SELECTION FROM MENU Selects items and monitor them.
Monitor item Contents
IGN ON SW “ON/OFF” Displays “IGN position (ON)/OFF, ACC position (OFF)” judged from the ignition switch signal.
ACC ON SW “ON/OFF” Displays “ACC (ON)/OFF, Ignition OFF (OFF)” status judged from ignition switch signal.
KEY ON SW “ON/OFF”Displays “Intelligent Key inserted into key slot (ON)/Intelligent Key removed from key slot
(OFF)” status judged from the key switch signal.
TURN SIGNAL R “ON/OFF” Displays status (turn right: ON/others: OFF) as judged from lighting switch signal.
TURN SIGNAL L “ON/OFF” Displays status (turn left: ON/others: OFF) as judged from lighting switch signal.
HI BEAM SW “ON/OFF”Displays status (high beam switch: ON/others: OFF) of high beam switch judged from lighting
switch signal.
