ANTI-LOCK BRAKE SYSTEM TS and CG Terminal Circuit

DESCRIPTION

In the Test Mode (signal check), a malfunction in the speed sensor that cannot be detected when the vehicle is stopped can be detected while driving.

Transition to the sensor check mode can be performed by connecting terminals 12 (TS) and 4 (CG) of the DLC3 and turning the ignition switch from off to ON.

  2. CHECK HARNESS AND CONNECTOR (DLC3 - BRAKE ACTUATOR ASSEMBLY)


    1. Turn the ignition switch off.

    2. Disconnect the B9 skid control ECU (brake actuator assembly) connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      D34-12 (TS) - B9-33 (TS) Always Below 1 Ω
      D34-12 (TS) or B9-33 (TS) - Body ground Always 10 kΩ or higher
    4. Reconnect the B9 skid control ECU (brake actuator assembly) connector.


    NG
    OK
  3. CHECK HARNESS AND CONNECTOR (DLC3 - BODY GROUND)


    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      D34-4 (CG) - Body ground Always Below 1 Ω

    NG
    OK
