WARNING: This page is about a different car, the 2004 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK DLC3 
    1. Turn the ignition switch to the LOCK position.
    2. Measure the resistance according to the value(s) in DLC3 CONNECTOR RESISTANCE SPECIFICATION TABLE  .

    Result: 

    DLC3 CONNECTOR RESISTANCE SPECIFICATION TABLE

    Tester connection Condition Specified value Result
    D3-6 (CANH) - D3-14 (CANL) Ignition SW OFF 108 to 132 Ω A
    D3-6 (CANH) - D3-14 (CANL) Ignition SW OFF 132 Ω or more 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 the 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. 
    1. B: REPAIR OR REPLACE DLC3 SUB BUS LINE OR CONNECTOR (CAN-H, CAN-L) 
    2. A: Go to Next Step. 
  2. CHECK CAN MAIN BUS LINE FOR DISCONNECTION (SKID CONTROL ECU - JUNCTION CONNECTOR) 
    1. Disconnect the connector (S1) from the skid control ECU.
    2. Measure the resistance according to the value(s) in SKID CONTROL ECU (S1) RESISTANCE SPECIFICATION TABLE  .

    Standard: 

    SKID CONTROL ECU (S1) RESISTANCE SPECIFICATION TABLE

    Tester connection Condition Specified value
    S1-11 (CANH) - S1-25 (CANL) Ignition SW OFF 108 to 132 Ω

    1. OK: REPLACE SKID CONTROL ECU WITH ACTUATOR 
    2. NG: Go to Next Step. 
  3. CHECK CAN MAIN BUS LINE FOR DISCONNECTION (JUNCTION CONNECTOR) 
    1. Disconnect all wire harness connectors (J5, J6, J8, J9) from the junction connector.
    2. Measure the resistance according to the value(s) in JUNCTION CONNECTOR RESISTANCE SPECIFICATION TABLE  .

    Standard: 

    JUNCTION CONNECTOR RESISTANCE SPECIFICATION TABLE

    Tester connection Condition Specified value
    1 (CANH) - 2 (CANL) Ignition SW OFF 108 to 132 Ω
