DTC C0044:14/C0044:1C/C0044:65/C0044:66/C0044:67 [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.
DETECTION CONDITION AND POSSIBLE CAUSE
| C0044:14 |
Brake fluid pressure sensor |
| C0044:1C |
| C0044:65 |
| C0044:66 |
| C0044:67 |
| DETECTION CONDITION |
C0044:14
- With the ECU terminal voltage within the normal range, the brake fluid pressure sensor power supply voltage is 4.4V or less
, or 5.6 V
or higher for a continuous 1.2 s
, or the brake fluid pressure sensor output voltage is 0.19 V or less
or exceeds 4.57 V
for a continuous 1.2 s.
C0044:1C
- 0-point output
- The brake fluid pressure sensor output value is 0.27 V
or less
or it exceeds 0.86 V
for a continuous 5 s
with the brake switch in the off condition.
- Output increase
- The following condition is detected 9 times
continuously (one detection period is when ignition is switched from ON to off)
- While the vehicle is traveling at a speed of 7 km/h {4 mph} or more
, the deceleration rate calculated from the brake fluid pressure sensor signal value is detected 5 times or more
at 1/4 or less than the normal value for a continuous 1 s
.
C0044:65/C0044:67
- Sticking
- While the vehicle is traveling at a speed of 7 km/h {4 mph} or more,
no fluctuation in the output voltage at 0.005 V or higher
is detected with the brake fluid pressure sensor output voltage exceeding 0.86 V
- Sticking during braking
- While the vehicle is traveling at a speed of 40 km/h {25 mph} or more
, the amount of fluctuation in the brake fluid pressure sensor value is detected 5 times
to be 0.048 MPa or less
until the vehicle speed reaches 0 km/h {0 mph}
and the brake switch ON.
C0044:66
- While the vehicle is traveling at a speed of 10 km/h {6.2 mph} or more
, a brake fluid pressure sensor signal value of 1,000 MPa/s
or more is detected 7 times or more
during a 5 s
period

| POSSIBLE CAUSE |
- DSC HU/CM malfunction
- Brake fluid pressure sensor malfunction
- Short or open circuit in brake fluid pressure sensor circuit
