DETERMINING OPEN CIRCUIT LOCATION (CAN-BUS No.1) [TYPE-B (R.H.D.)]

id100271001700

Caution

• Perform the following malfunction diagnosis only when it is diagnosed with a open circuit by CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [TYPE-B (R.H.D.)]. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [TYPE-B (R.H.D.)].)

• 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 module displayed in red or blue on the M-MDS screen.

2. Apply the communication error DTC and the module displayed in red or blue to the DTC output pattern and malfunctioning location, and select the possible cause for the diagnostic result and the reference for the inspection item. (See DTC Output Pattern And Malfunctioning Location)

Note

• The open circuit location can be determined by the DTC indicated in the DTC output pattern and malfunctioning location chart. DTCs not listed in the chart are not used for the determination of the open circuit location. (See DTC Output Pattern And Malfunctioning Location.)

• The module may be displayed in red or blue on the M-MDS screen even if there is no malfunction depending on the vehicle specification.

3. Inspect the possible cause and inspection item of the applicable malfunctioning part.
