General Information: DTC Detecting Condition

2011 Hyundai Santa Fe GLS, 3.5 G, AWDSECTION DTC Detecting Condition
DTC DETECTION CONDITION AND POSSIBLE CAUSES

Item Detecting Condition Possible Cause
DTC Strategy
  • Voltage monitoring
  • Open or short of Wheel speed sensor circuit (RL)
  • Faulty Wheel speed sensor (RL)
Case 1 Monitoring Period
  • Once after power up.
Enable Conditions
  • Shorts between WSS lines and shorts to UZ can be detected by switching single WSS channels in sequence. If there is an error after end of test, a failure is recognized.
    NOTE: In case of a WSS power line short to V_batt, this FSA test will detect an under voltage failure. (ABS only)

    * FSA test : fail save circuit test

    * UZ : Ignition Voltage
Case 2 Monitoring Period
  • Continuous
Enable Conditions
  • When the sensor current levels are out of permissible range (LOW : 7mA, HIGH : 14mA) for 200ms.
Fail-Safe
  • Sensor failure outside of the ABS control cycle
    1. 1~2 wheel failure
      • Only the ABS/ESC functions are inhibited.
      • The ABS/ESC warning lamps are activated and the EBD warning lamp is not activated.
    2. More than 3 wheels failure
      • The ABS/EBD/ESC functions are inhibited.
      • The ABS/EBD/ESC warning lamps are activated.
  • Sensor failure inside the ABS control cycle
    1. 1~2 wheel failure
      • The ABS/ESC functions are inhibited after end of control.
      • The ABS/ESC warning lamps are activated and the EBD warning lamp is not activated.
    2. More than 3 wheels failure
      • The ABS/EBD/ESC functions are inhibited.
      • The ABS/EBD/ESC warning lamps are activated.

        * Control of the corresponding wheel is no longer possible. If a sensor fault occurs on a front wheel, pressure is increased; on a rear wheel, pressure is decreased.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
