Diagnostic Method
Fluid pressure control performance degraded (high pressure).
JUDGMENT VALUE SPECIFICATION
| Malfunction Criteria | Threshold Value |
|---|---|
| Target servo pressure - Actual servo pressure | Exceeds Table 1 MPa |
| Response Time | Exceeds Table 2 sec. |
SERVO PRESSURE AND THRESHOLD VALUE SPECIFICATION
| Servo pressure (MPa) | Threshold Value (MPa) | |
|---|---|---|
| ABS ON | ABS OFF | |
| 0.00 | 2.70 | 1.5 |
| 7.00 | 2.70 | |
| 13.07 | 4.14 | |
TARGET SERVO PRESSURE GRADIENT AND THRESHOLD VALUE SPECIFICATION
| Target servo pressure gradient (MPa/sec) | Threshold Value (sec) | |
|---|---|---|
| Running | Not Running | |
| 0 | 3.20 | 3.67 |
| 1.02 | 1.94 | 2.64 |
| 2.01 | 1.42 | 1.50 |
| 5.01 | 0.78 | 0.85 |
| 9.99 | 0.48 | 0.54 |
| 20.01 | 0.42 | 0.43 |
| 30 | 0.34 | 0.34 |
| 39.99 | 0.30 | 0.31 |

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 | 0.72 |
| Not Running | 2.50 |
Malfunction indicator light illumination: Illuminates as soon as a malfunction occurs.
