Was bedeutet der Fehlercode?
The signal to hydraulic valve 3 is too high or too low. The wire between the roof control module (CRM) and the valve may be broken or shorted to ground or voltage. A failed valve with an internal short to ground, or an internal fault in the control module, can also cause the code. Roof movement may be restricted.
Mögliche Ursachen
- Open circuit in the wire between the roof control module and hydraulic valve 3
- The wire between the roof control module and hydraulic valve 3 is shorted to ground or voltage
- Hydraulic valve 3 does not work, with an internal short to ground
- Internal fault in the roof control module (CRM)
Was Sie tun können
- 1Clear the fault code and test the roof in both directions to see whether it comes back
- 2Look only at the wires to hydraulic valve 3, since that is what the fault code refers to
- 3Measure with a multimeter that the wire has no break and is not shorted to ground or voltage
- 4If a fault is found in the wire, replace it. Otherwise a workshop may need to replace the hydraulic pump
- 5If the fault still remains after this, a workshop needs to check the roof control module
