Inspection Procedure

  1. CHECK DLC3 
    1. Measure the resistance according to the value(s) in DLC3  .

      Standard resistance 

      DLC3

      Tester connection Condition Specified value Result
      D1-6 (CANH) - D1-14 (CANL) IG switch OFF 108 to 132 Ω A
      D1-6 (CANH) - D1-14 (CANL) IG switch OFF 132 Ω or higher B

      NOTE: When the measured value is 132 Ω or more and the CAN communication system diagnostic code is output, there may be a fault besides disconnection of the DLC3 sub bus line. For that reason, troubleshooting should be performed again from "How to proceed with troubleshooting" after repairing the trouble area.

    B: REPAIR OR REPLACE DLC3 SUB BUS LINE OR CONNECTOR (CAN-H, CAN-L) 

    A: GO TO NEXT STEP 

  2. CHECK CAN MAIN BUS LINE (SKID CONTROL ECU - JUNCTION CONNECTOR) 
    1. Disconnect the connector (J13) from the junction connector.
    2. Measure the resistance according to the value(s) in SKID CONTROL ECU - JUNCTION CONNECTOR  .

      Standard resistance 

      SKID CONTROL ECU - JUNCTION CONNECTOR

      Tester Connection Condition Specified value
      J13-4 (CANH) - J13-15 (CANL) IG switch OFF 108 to 132 Ω

    NG: Go to step  4

    OK: GO TO NEXT STEP 

  3. CHECK STEERING SENSOR 
    1. Disconnect the connector (S12) from the steering sensor.
    2. Measure the resistance according to the value(s) in STEERING SENSOR  .

      Standard resistance 

      STEERING SENSOR

      Tester Connection Condition Specified value
      10 (CANH) - 9 (CANL) IG switch OFF 108 to 132 Ω

    NG: REPLACE STEERING SENSOR 

    OK: REPAIR OR REPLACE CAN MAIN BUS LINE OR CONNECTOR (STEERING SENSOR - JUNCTION CONNECTOR) 

  4. CHECK SKID CONTROL ECU 
    1. Disconnect the connector (S1) from the skid control ECU.
    2. Measure the resistance according to the value(s) in SKID CONTROL ECU  .

      Standard resistance 

      SKID CONTROL ECU

      Tester Connection Condition Specified value
      11 (CANH) - 25 (CANL) IG switch OFF 108 to 132 Ω
