VEHICLE STABILITY CONTROL SYSTEM CALIBRATION

SST
A00Y6CU 09843-18040 Diagnosis Check Wire No. 2

  1. DESCRIPTION


    1. Refer to the table below and then perform the necessary operation according to the part to be replaced in order to perform calibration.

      Parts to be Replaced Necessary Operation
      Skid control ECU (brake actuator assembly) Perform system variant learning
  2. SYSTEM VARIANT LEARNING (When Using GTS)


    1. Perform system variant learning.

      Tech Tips


      • System variant learning is automatically performed immediately after Test Mode is entered.

      • If learning has not yet been performed, the slip indicator light will remain on and DTC C1288 (Error in Matching of ECUs) will be stored.

      • If system variant learning is not successful, the warning lights will not blink in the Test Mode pattern and DTC C1288 will not be cleared.


      1. Turn the ignition switch off.

      2. Connect the GTS to the DLC3.

      3. Turn the ignition switch to ON.

      4. Turn the GTS on.

      5. Switch the skid control ECU (brake actuator assembly) to Test Mode using the GTS. Enter the following menus: Chassis / ABS/VSC/TRC / Utility / Test Mode.


        Chassis > ABS/VSC/TRC > Utility
        Tester Display
        Test Mode
      6. Check that the ABS warning and slip indicator lights blink in the Test Mode pattern.

        Tech Tips

        After the skid control ECU (brake actuator assembly) enters Test Mode, the slip indicator light may remain on for approximately 7 seconds before starting to blink in the Test Mode pattern.

      7. Turn the ignition switch off and disconnect the GTS.

  3. SYSTEM VARIANT LEARNING (When Using SST Check Wire)


    1. Perform system variant learning.

      Tech Tips


      • System variant learning is automatically performed immediately after Test Mode is entered.

      • If learning has not yet been performed, the slip indicator light will remain on and DTC 88 (Error in Matching of ECUs) will be stored.

      • If system variant learning is not successful, the warning lights will not blink in the Test Mode pattern and DTC 88 will not be cleared.


      1. Turn the ignition switch off.

      3. Turn the ignition switch to ON.

      4. Check that the ABS warning and slip indicator lights blink in the Test Mode pattern.

        Tech Tips

        After the skid control ECU (brake actuator assembly) enters Test Mode, the slip indicator light may remain on for approximately 7 seconds before starting to blink in the Test Mode pattern.

      5. Turn the ignition switch off and disconnect SST from the DLC3.
