WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
DETECTION CONDITION & POSSIBLE CAUSE
| 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, TCS/DSC indicator light, and smart city brake support (SCBS) indicator light (amber) *1.
Tire pressure monitoring system warning light *1
illuminates after flashes.
- Inhibits the ABS, TCS, DSC, brake assist control, hill launch assist (HLA), TPMS *1,
and smart city brake support (SCBS) *1
controls. (Additionally, when any malfunction is detected in two wheels or more, EBD control is inhibited and the brake system warning light is illuminated.)
*1:
If equipped. |
| 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 F-RF ABS wheel-speed sensor terminal B
- DSC HU/CM terminal C-RF ABS wheel-speed sensor terminal A
- DSC HU/CM terminal AG-LF ABS wheel-speed sensor terminal B
- DSC HU/CM terminal AJ-LF ABS wheel-speed sensor terminal A Without electric parking brake
- DSC HU/CM terminal AA-RR ABS wheel-speed sensor terminal A
- DSC HU/CM terminal X-RR ABS wheel-speed sensor terminal B
- DSC HU/CM terminal L-LR ABS wheel-speed sensor terminal A
- DSC HU/CM terminal O-LR ABS wheel-speed sensor terminal B With electric parking brake
- DSC HU/CM terminal AA-RR ABS wheel-speed sensor terminal B
- DSC HU/CM terminal X-RR ABS wheel-speed sensor terminal D
- DSC HU/CM terminal L-LR ABS wheel-speed sensor terminal B
- DSC HU/CM terminal O-LR ABS wheel-speed sensor terminal D
- Malfunction in the ABS wheel-speed sensor
- Poor connection at connectors (female terminal)
- DSC HU/CM malfunction
