DTC Information: DTC Detecting Condition

WARNING: This page is about a different car, the 2021 Kia Soul. However, it is still accessible from the selected car via links, so may be relevant.
Item Detecting Condition Possible Cause
DTC Strategy
  • Signal monitoring (rationality check)
  • Poor connector connection
  • Damages or faulty tone wheel
  • Faulty signal circuit of rear-RH wheel speed sensor
  • Faulty wheel speed sensor rear-RH
Enable Condition
  • Ignition "ON"
Threshold Value Case1
  • In case of large air gap between tone wheel and wheel speed sensor, there is no pulse signal input and ESC recognizes wheel speed as 0km/h (0MPH)

A failure is detected by comparison of the 4 wheels speed in following conditions.
  1. A failure is detected in case that the slowest wheel speed is below 0.25km/h (0.16MPH) and the speed of other wheels exceed 10km/h (6.2MPH) with the vehicle acceleration under 0.4g and this condition continues 150ms
  2. A failure is detected in case that two or more wheels speed is below 2km/h (1.24MPH) and the speed of other wheel(s) exceed 10km/h with the vehicle acceleration under 0.4g and this condition continues 20s
  3. If the vehicle acceleration is above 0.4g in 1), 2), the failure detection time is 3min.
  4. A failure is detected in case that one or two wheel speed is below 0.25km/h (0.16MPH) for more than 12s after all wheels exceed 10km/h (6.2MPH)In case two non-driven is below 0.25km/h (0.16MPH), the failure detection time is 2min.

* 0.4g: About 14km/h (8.7MPH) per 1s
Case2
  • A failure is detected if the wheel speed is below 2km/h (1.2MPH) for more than 12s during ABS control
  • A failure is detected if the ABS control duration exceeds 36s (In this case, ESC recognizes all wheels are defective)
  • A failure is detected if the wheel speed is above 512km/h (318MPH) for more than 100ms
Warning Lamp
  • In case of failure on more than one wheel
    • ESC/DBC/AVH warning lamp "ON"
  • In case of failure on more than two wheels
    • EBD warning lamp "ON"
  • In case of failure on all wheels
    • Warning lamp "ON"
Disable Condition
  • Ignition "OFF" and then "ON", specified vehicle speed is maintained
