DETERMINING MALFUNCTIONING PART (HS-CAN) [MULTIPLEX COMMUNICATION SYSTEM (L.H.D.)]

id0902j3846700

  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 “×“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 DTC TABLE [MULTIPLEX COMMUNICATION SYSTEM (L.H.D.)].)

3. Refer to the matching tandem diagnostic results (A to V) and inspect the possible cause and inspection item.

4. Perform the DTC inspection after the repair procedure.

  • If any DTC is displayed, return to FOREWORD. (See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (L.H.D.)].)
