DETERMINING OPEN CIRCUIT LOCATION (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. |
- Verify the CAN system-related module DTCs and the failed module on the M-MDS screen.
- Refer to " «DTC OUTPUT PATTERN AND MALFUNCTIONING PART»(ref-367616-S03388209162010072700000) " and find the area linked from the malfunctioning part. NOTE: A hyphen (-) in the DTC output pattern cell indicates that the DTC may be displayed depending on the malfunction detection conditions. If it is not displayed, the malfunctioning part can be determined by checking only the crosses (x.) If any of the following DTCs is displayed alone, perform the applicable DTC inspection. (See «DTC TABLE [MULTIPLEX COMMUNICATION SYSTEM]»(ref-367616-S32724682352010072700000) .) Instrument cluster: U1900 EPS control module: U1900 DSC HU/CM: U1900 Keyless control module: U1147, U2510 Steering angle sensor: U1900
- Inspect the possible cause and inspection item of the applicable malfunctioning part.
- Perform the DTC inspection after the repair procedure. If any DTC is displayed, return to «FOREWORD [MULTIPLEX COMMUNICATION SYSTEM]»(ref-367616-S07945634952010072700000) .
DETERMINE OPEN CIRCUIT LOCATION (MS-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. |
- Verify DTCs of the modules related to the CAN system.
- Apply the following items to the DTC output pattern and the malfunctioning location, and then verify the reference to the malfunctioning location. Communication error DTCs Display status of the air conditioner/audio control on the information display when the climate control unit/either of the audio unit or the car-navigation unit is operated. The operation condition of the SIRIUS satellite radio system and the hands-free telephone system. NOTE: A hyphen (-) in the DTC output pattern cell indicates that the DTC may or may not be displayed depending on the malfunction detection conditions. If it is not displayed, the malfunctioning location can be determined by checking the crosses (x) and asterisks (*.)
- Inspect the possible cause and inspection item of the applicable malfunctioning part.
- Perform the DTC inspection after the repair procedure. If any DTC is displayed, return to «FOREWORD [MULTIPLEX COMMUNICATION SYSTEM]»(ref-367616-S07945634952010072700000) .
