DTC C0031:23/C0031:27/C0031:62/C0034:23/C0034:27/C0034:62/C0037:23/C0037:27/C0037:62/C003A:23/C003A:27/C003A:62 [Dynamic Stability Control (DSC)]: Notes
WARNING: This page is about a different car, the 2009 Mazda 6. 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 C0037:23 and C003A:23 are input to the memory.

| DETECTION CONDITION |
C0031:23/C0031:62/C0034:23/C0034:62/C0037:23/C0037:62/C003A:23/C003A:62
- Abnormal sensor output is detected on any of four vehicle ABS wheels when the vehicle goes from start to a speed of 10 km/h {6.2 mph}.
- Greater than specified amount of ABS demand occurs from front ABS wheel sensors when vehicle is started.
- The following condition is detected 8 times
continuously (one detection period is when ignition is switched from ON to off)
- While the vehicle is traveling at a speed of 20 km/h {12.4 mph} or more
, the wheel speed signal from the rear wheels is not input to the DSC HU/CM for a continuous 20 s
.
C0031:27/C0034:27/C0037:27/C003A:27
- Periodic abnormality is detected in the signal wave pattern from the ABS wheel-speed sensor
- ABS control continues to operate for 45 s or more
|
| POSSIBLE CAUSE |
- Connector or terminal malfunction
- Short to ground in wiring harness between following terminals:
- LF ABS wheel-speed sensor terminal B and DSC HU/CM terminal P
- RF ABS wheel-speed sensor terminal B and DSC HU/CM terminal 0
- LR ABS wheel-speed sensor terminal B and DSC HU/CM terminal I
- RR ABS wheel-speed sensor terminal B and DSC HU/CM terminal J
- ABS wheel-speed sensor malfunction
- Sensor rotor malfunction
- Incorrect clearance between ABS wheel-speed sensor and sensor rotor
- Poor installation of sensor rotor
- DSC HU/CM malfunction
- Solenoid valve malfunction
- Pump motor malfunction
- Pipe clogging
