Diagnostic Method
Fluid pressure control performance degraded (low pressure).
JUDGMENT VALUE SPECIFICATION
| Malfunction Criteria | Threshold Value |
|---|---|
| Target servo pressure - Actual servo pressure | Exceeds Table 1 MPa |
| Response Time (Only Brake On) | Exceeds Table 2 sec. |
SERVO PRESSURE AND THRESHOLD VALUE SPECIFICATION
| Servo pressure (MPa) | Threshold Value (MPa) | |
|---|---|---|
| ABS ON | ABS OFF | |
| 0.00 | 4.00 | 0.5 |
| 1.00 | 4.00 | |
| 3.00 | 3.00 | |
| More than 5.00 | 1 | |
TARGET SERVO PRESSURE GRADIENT AND THRESHOLD VALUE SPECIFICATION
| Target servo pressure gradient (MPa/sec) | Threshold Value (sec) |
|---|---|
| Less than -20.00 | 0.30 |
| -10.00 | 0.32 |
| -2.00 | 1.25 |
| -1.00 | 1.70 |
| 0.00 | 2.10 |
Time needed for diagnosis: Time depends on vehicle running state or ABS operation state.
| Vehicle State | Time Required (sec) |
| Running ABS ON | 0.36 |
| Running ABS OFF | 0.54 |
| Not Running | 2.50 |
Malfunction indicator light illumination: Illuminates as soon as a malfunction occurs.
