CAN COMMUNICATION SYSTEM(for RHD), Diagnostic DTC:U1002

DESCRIPTION

• The main body ECU (driver side junction block) stores this DTC when no signals can be received from the ECUs that have been memorized as those connected to the MS bus circuit.

• When the main body ECU (driver side junction block) receives a response signal from the ECUs connected to the MS bus circuit, the main body ECU (driver side junction block) recognizes and memorizes that the ECU is connected to the MS bus circuit. Based on this memorized data, the main body ECU (driver side junction block) monitors for malfunctions in the ECUs connected to the MS bus circuit when communicating with those ECUs. If the main body ECU (driver side junction block) cannot receive response signals from the ECUs that have been memorized as those connected to the MS bus circuit, the main body ECU (driver side junction block) determines that a malfunction exists.

• If 2 or more DTCs are output during the DTC check, one side of the CAN branch wire may be open (one side of the CANH [CAN branch wire]/CANL [CAN branch wire] of the ECU and/or sensor is open).

• *1: w/ Tire Pressure Warning System

• *2: w/ Pre-crash Safety System

PROCEDURE

1. PRECAUTION

   Note

   After turning the power switch off, waiting time may be required before disconnecting the cable from the auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the auxiliary battery terminal notice before proceeding with work Click here.

   
   

   NEXT

2. DISCONNECT CABLE FROM NEGATIVE AUXILIARY BATTERY TERMINAL

   
   

   1. Disconnect the cable from the negative (-) auxiliary battery terminal before measuring the resistances of the CAN main wire and the CAN branch wire.

      CAUTION:

      Wait at least 90 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.

      Note

      When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.
