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.
NOTE:
- When only the driving wheels are rotated while the vehicle is jacked up, DTCs C0037:29 and C003A:29 are input to the memory.

| C003A:07, C003A:29, C003A:2F, C003A:64 |
RR ABS wheel-speed sensor/ABS sensor rotor |
| DETECTION CONDITION |
- C0030:07, C0033:07, C0036:07, C0039:07
- Periodic abnormality is detected in the signal wave pattern from the ABS wheel-speed sensors.
- C0031:07, C0034:07, C0037:07, C003A:07
- While the vehicle is traveling at a speed of 10 km/h {6.2 mph} or more, no signal in any of the four wheels or an extremely low vehicle speed signal is detected.
- C0031:29, C0034:29, C0037:29, C003A:29
- The wheel-speed signal is not input or an extremely low wheel-speed signal is detected from any of the four wheels when driving at a vehicle speed of 10 km/h {6.2 mph} or more
- C0031:2F, C0034:2F, C0037:2F, C003A:2F
- The wheel speed or acceleration speed in any of the 4 wheels is not within the specification.
- ABS control continues to operate for 28 s or more.
- C0031:64, C0034:64, C0037:64, C003A:64
- While the vehicle is traveling at a speed of 20 km/h {12 mph} or more, an extremely high vehicle speed signal in any of the four wheels is detected.

| 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 illuminates after flashes.
- Inhibits the ABS, TCS, DSC, brake assist control, hill launch assist (HLA), TPMS, 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 |
- ABS sensor rotor malfunction (missing ABS sensor rotor teeth due to foreign material obstruction)
- ABS wheel-speed sensor or ABS sensor rotor installation malfunction (If the ABS sensor rotor is installed at an angle, it may cause output of abnormal wave pattern at high speeds.)
- Excessive clearance between the ABS wheel-speed sensor and sensor rotor
- ABS wheel-speed sensor malfunction
- Continuous ABS operation
- DSC HU/CM malfunction
