Supports inspections and adjustments. Commands are transmit-
ted to the BCM for setting the status suitable for required opera-
tion, input/output signals are received from the BCM and received
data is displayed.
DATA MONITOR Displays BCM input/output data in real time.
ACTIVE TEST Operation of electrical loads can be checked by sending drive sig-
nal to them.
SELF-DIAG RESULTS Displays BCM self-diagnosis results.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication
can be read.
ECU PART NUMBER BCM part number can be read.

How to Perform Trouble Diagnosis for Quick and Accurate RepairEES001IA
INTRODUCTION

Before troubleshooting, verify customer complaints.

If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal-
functioning. Hold and shake these parts to make sure they are securely connected.

When using a circuit tester to measure voltage or resistance of each circuit, be careful not to damage or
deform connector terminals.
