VEHICLE STABILITY CONTROL SYSTEM(for TMMF Made) DIAGNOSTIC TROUBLE CODE CHART

Note

When removing any parts, turn the ignition switch off.

Tech Tips


  • If no abnormality is found when inspecting parts, check the skid control ECU and check for poor contact at ground points.

  • If a DTC is displayed during the DTC check, check the circuit for the DTC listed in the table below. For details of each DTC, refer to the page indicated.

  • When 2 or more DTCs are detected, perform circuit inspection one by one until the problem is identified.

  • All DTCs in the table below are detected in accordance with 1 trip detection logic.

Tech Tips


  • *1: Even after the trouble areas are repaired, the ABS warning light will not go off unless the following operations are performed.


    1. Drive the vehicle at 20 km/h (12 mph) for 30 seconds or more and check that the ABS warning light goes off.

    2. Clear the DTC(s).
