Inspection Procedure

HINT:

• Refer to inspection procedure for CAN communication system (See HOW TO PROCEED WITH TROUBLESHOOTING ).
• If the CAN communication malfunctions, the ECU cannot receive the current data from the ECM. However, reading the Data List as the first step of troubleshooting is effective to find malfunctions.
• The malfunction area can be checked using the BUS CHECK function of the intelligent tester (See DIAGNOSIS SYSTEM ).
