| DTC Strategy |
|
- Poor connector connection
- Large air gap
- Faulty signal circuit of WSS front-LH
- Faulty WSS front-LH
- Wrong size tire
- Faulty IEB module
|
| Enable Condition |
- Ignition "ON"
- Auxiliary battery normal voltage (8 to 16V)
|
| Threshold Value |
Case 1 |
- Large air gap between tone wheel and WSS, there is no pulse signal input and ABS/ESC recognizes wheel speed as 0 kph (0 mph)
- The slowest wheel speed is below 0.25 kph (0.16 mph) and all other wheel speeds exceed 10 kph (6.2 mph) with the vehicle acceleration under 0.4g and this condition continues 160s
- Two or more wheels speed is below 2 kph (1.2 mph) and the speed of other wheel(s) exceed 10 kph (6.2 mph) with the vehicle acceleration under 0.4g and this condition continues 20s
- If the vehicle acceleration is greater than 0.4g in first, second condition the failure detection time 3 minutes
- One or two wheel speed is below 0.25 kph (0.16 mph) longer than 12s after all wheels exceed 10 kph (6.2 mph). However, If All non-dive wheel are less than 0.25 kph (0.16 mph), fault detection time is 120s
|
| Case 2 |
- If the wheel speed is below 2 kph for 20s under ABS control
- All WSS failure is detected when abnormal ABS control is continues for 36s
- If the wheel speed is greater than 512 kph (318 mph) longer than 100 ms
