Outline of troubleshooting

When there is a trouble with CAN, perform TROUBLESHOOTING FOR COMMUNICATION ERROR WITH SCAN TOOL USING CAN  and/or TROUBLESHOOTING FOR CAN-DTC . Not using this procedure or performing troubleshooting in any other way may skip some check points resulting in misdiagnosis or take a longer time than necessary.

1. Checking connector related to CAN
2. Checking CAN line
3. Checking each control module/sensor using "DTC check" or "Bus Check"
4. Checking power and ground connection of each control module/sensor
