| Meaning of the fault codes |
|
| Fault: |
|
Number of flashes Blocks 3 and 4: |
|
| No fault found |
|
1 |
|
| Control unit - internal fault |
|
2 |
|
| Signal path rpm sensor1 (DF): |
|
|
|
DF shaft 1, impermissible gap or short circuit |
|
3 |
|
DF shaft 2, impermissible gap or short circuit |
|
4 |
|
DF shaft 3, impermissible gap or short circuit |
|
5 |
|
DF shaft 1, break or short circuit |
|
6 |
|
DF shaft 2, break or short circuit |
|
7 |
|
DF shaft 3, break or short circuit |
|
8 |
|
| Low voltage or valve relay1 cannot be controlled |
|
9 |
|
| Signal path pressure control valve1 (DSV): |
|
|
|
Pressure control valve shaft 1: |
|
10 |
|
Pressure control valve shaft 2: |
|
11 |
|
Pressure control valve shaft 3: |
|
12 |
|
| Valve relay1 cannot be switched (sticking) |
|
13 |
|
| Signal path ASR valve1 |
|
14 |
|
| impermissible configuration |
|
15 |
|
| 1 depending on the block, theFlashing sequence and the corresponding diagonal, the left or right side is affected. |
|
|
| Notes: |
- Fault 9 will only be saved if the cause (low voltage or valve relay cannot be switched) was present for at least 30 seconds.
- Fault 15 will only be saved if on shaft 3 only one 1K-DSV for both wheels (Select-low-control) and one 2-channel ASR solenoid (or two 1-channel valves) are connected for braking control. This is not permitted, as there must be a 1K-DSV present for ASR braking control operation.
