DATA MONITOR
ALL SIGNALS
• Displays the status of the following vehicle signals inputted into AV control unit.
• For each signal, actual signal can be compared with the condition recognized on the system.
• AV COMM CIRCUIT [U1300]
• SONAR CONN [U125C]
When either one of the following items
are detected:
• Sonar control unit power supply or
ground circuit malfunction are detected.
• Malfunction is detected in the AV com-
munication circuits between sonar con-
trol unit and the junction between AV
control unit and multifunction switch.
• Sonar control unit power supply and
ground circuits.
• AV communication circuits between so-
nar control unit and the junction between
AV control unit and multifunction switch.
• AV COMM CIRCUIT [U1300]
