DTC DETECTING CONDITION

DTC No. Detecting Condition Possible Cause
C1237 [Noisy signal, offset, stick]
  • If input signal is noisy, Which the gradient of the sensor signal is larger than 15bar over 25times in 2sec, ECU detect the failure.
  • Outside an ABS/TCS/ESP control, And after normal operation of BLS, If the pressure sensor signal is higher than 20bar and BLS is low for 3sec, ECU detect the failure.
  • Open/Short in the pressure sensor circuit
  • Faulty the pressure sensor
  • Faulty installing of the pressure sensor
  • Faulty HECU
