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 circuit in brake switch line
  • Faulty brake light switch
Case 1 Monitoring Period
  • Continuous (only no under voltage is detected)
Enable Conditions
  • If the BLS-signals is high for 60 s at following condition.
    1. the gas pedal is stepped
    2. vehicle speed > 10.8km/h
    3. offset compensated pressure < 5 bar
    4. no control is active
Case 2 Monitoring Period
  • Continuous (only normal voltage)
Enable Conditions
  • For redundancy reasons an additional BLSpVor-signal is created by the pressure sensor signal. If the pressure sensor is compensated, the threshold for generating the BLSpVor signal is 10 bar. If the pressure sensor is not compensated, the threshold is increased by 15bar. If this signal is set without any hardware-BLS-signals and if no pomp is operated during that time, a fault is set after the braking.
  • If the pressure signal is higher than 80bar and not both of the hardware-BLS are set, a fault is stored after 1s.
Fail-Safe
  • Inhibit the ESC control and allow the ABS/EBD control.
  • The ESC warning lamp is activated.

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.
