ANTI-LOCK BRAKE SYSTEM TS and CG Terminal Circuit

DESCRIPTION

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

Sensor check mode can be entered by connecting terminals TS and CG of the DLC3 and turning the ignition switch from off to ON.

CAUTION / NOTICE / HINT

Note


  • When replacing the brake actuator assembly (skid control ECU) or deceleration sensor, be sure to perform deceleration sensor 0 point calibration and CVT oil pressure calibration after performing AT/CVT learned values initialization.

  • Perform the test mode procedure after the initialization (perform the test mode start only after the brake actuator assembly (skid control ECU) is replaced).

    Tech Tips

    By performing the test mode start, the identification code of the brake actuator assembly (skid control ECU) is re-registered.

  3. CHECK HARNESS AND CONNECTOR (POWER STEERING ECU ASSEMBLY - TS of DLC3)


    1. Turn the ignition switch off.

    2. Disconnect the F6 power steering ECU assembly connector.

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

      Standard Resistance (Check for Open)
      Tester Connection Condition Specified Condition
      F4-12 (TS) - F6-6 (TS) Always Below 1 Ω
      Standard Resistance (Check for Short)
      Tester Connection Condition Specified Condition
      F4-12 (TS) - Body ground Always 10 kΩ or higher

    4. Reconnect the power steering ECU assembly connector.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. CHECK HARNESS AND CONNECTOR (CG of DLC3 - BODY GROUND)


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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F4-4 (CG) - Body ground Always Below 1 Ω

    1. Turn the ignition switch off.

    2. Using SST, connect terminals TS and CG of the DLC3.

    3. Turn the ignition switch to ON.

    4. Check that the check PS warning light is blinking.

      Result
      Result Proceed to
      Check PS warning light is not blinking A
      Check PS warning light is blinking (for LHD) B
