DTC C1203 DETECTING CONDITION CHART

Item Detecting Condition Possible cause
DTC Strategy
  • Current Monitoring
  • Open or short Wheel speed sensor circuit (FR)
  • Faulty Wheel speed sensor (FR)
  • Faulty HECU
Detect Mode
  • Initial Check
  • Outside the ABS control cycle
  • Inside the ABS control cycle
  • Diagnosis mode
  • Failure mode
 -
Enable Conditions
  • When the sensor signal current is continuously out of the specified range of 4 mA ± 10% ~ 22 mA ± 10% for 140msec.
Fail Safe
  • Sensor failure outside of the ABS control cycle
    1. Only one 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 two wheels failure : System down. The ABS/EBD/ESC functions are inhibited. The valve relay and all solenoids are prevented from being switched on. The ABS/EBD/ESC warning lamps are activated.
  • Sensor failure inside the ABS control cycle
    1. One front wheel failure : Inhibit the ABS/ESC control of the failed-wheel and maintain the ABS/ESC control of normal wheel. After the ABS/ESC control, the ABS/ESC functions are inhibited. The ABS/ESC warning lamps are activated and the EBD warning lamp is not activated.
    2. Failure at one rear wheel : ABS/ESC control of both front wheels are inhibited and the pressure of both rear wheels are decreased. After the controller completes the ABS/ESC control, the ABS/ESC functions are inhibited. The ABS/ESC warning lamps are activated and the EBD warning lamp is not activated.
    3. More than 2 wheels failure : System down. The ABS/EBD/ESC functions are inhibited. The valve relay and all solenoids are prevented from being switched on. The ABS/EBD/ESC warning lamps are activated.

  • • 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.
