DTC C0031:11/C0031:15/C0034:11/C0034:15/C0037:11/C0037:15/C003A:11/C003A:15 [Dynamic Stability Control (DSC)]: Notes

DTC C0031:11, C0031:15 LF ABS wheel-speed sensor
C0034:11, C0034:15 RF ABS wheel-speed sensor
C0037:11, C0037:15 LR ABS wheel-speed sensor
C003A:11, C003A:15 RR ABS wheel-speed sensor
DETECTION CONDITION 
  • C0031:11, C0034:11, C0037:11, C003A:11
    • Short to ground has been detected in the ABS wheel-speed sensor wiring harness on any of the four vehicle wheels.
  • C0031:15, C0034:15, C0037:15, C003A:15
    • Open circuit or short to power supply has been detected in the ABS wheel-speed sensor wiring harness on any of the four vehicle wheels.
FAIL-SAFE FUNCTION 
  • Illuminates the ABS warning light and TCS/DSC indicator light.
  • Inhibits the ABS, TCS, DSC and brake assist controls.

    (Additionally, when any malfunction is detected in two wheels or more, EBD control is inhibited and the brake system warning light is illuminated.)

POSSIBLE CAUSE 
  • Open circuit or short to ground/power supply in the wiring harness between the following DSC HU/CM terminals and ABS wheel-speed sensor terminals:
    • DSC HU/CM terminal AP-RF ABS wheel-speed sensor terminal A
    • DSC HU/CM terminal AS-RF ABS wheel-speed sensor terminal B
    • DSC HU/CM terminal I-LF ABS wheel-speed sensor terminal A
    • DSC HU/CM terminal F-LF ABS wheel-speed sensor terminal B
    • DSC HU/CM terminal O-RR ABS wheel-speed sensor terminal A
    • DSC HU/CM terminal R-RR ABS wheel-speed sensor terminal B
    • DSC HU/CM terminal AJ-LR ABS wheel-speed sensor terminal A
    • DSC HU/CM terminal AG-LR ABS wheel-speed sensor terminal B
  • Malfunction in the ABS wheel-speed sensor
  • Poor connection at connectors (female terminal)
