DETERMINING MALFUNCTIONING PART (HS-CAN) [MULTIPLEX COMMUNICATION SYSTEM]
CAUTION:
-
If the malfunctioning part is detected in the communication line, before disconnecting the related connector for inspection, press the connector in
the connection direction to verify that there is no looseness or disconnection.
-
When disconnecting the connector, verify that there is no damage, deformation, or corrosion of the connector terminals.
1. Verify the CAN system-related module DTCs and the failed module using the (M-MDS).
2. Look for a DTC display pattern and failed module display pattern in tandem which match.
NOTE:
-
A hyphen " - " in the DTC output pattern table indicates that the DTC may be displayed depending on the malfunction detection conditions. If
only an " x " is indicated, it means the DTC will not be displayed.
-
If any of the following DTCs is displayed alone, perform the applicable DTC inspection. See: Testing and Inspection/Diagnostic Trouble
