- If the CAN system is considered to be the cause of the malfunction based on the repair order form and the malfunctioning symptom, follow the Troubleshooting Procedure.
- DTCs are also output due to a control module or sensor malfunction, or incorrect power supply. Verify the output DTCs and first inspect the DTCs not shown in DTC TABLE [MULTIPLEX COMMUNICATION SYSTEM].
- If there is an open circuit in the communication lines, it is possible that signal error DTCs may be output in addition to communication error DTCs. Perform DETERMINING MALFUNCTIONING PART (HS-CAN) [MULTIPLEX COMMUNICATION SYSTEM] if the communication error and signal error DTCs are output simultaneously.
