Was bedeutet der Fehlercode?

The engine control module (ECM) communicates with the electric coolant pump over the LIN bus and monitors that communication. The code is set when there is an open circuit on the wire between the control module and the pump, either on the LIN bus or in the power supply. The fault shows up as uneven temperature, and the pump then runs at full speed.

Mögliche Ursachen

Communication fault on the LIN bus
Contact resistance, oxidation or a break in the connections
Open circuit in the signal ground wire

Was Sie tun können

1Check that the fuses are intact
2Check the connectors to the coolant pump for contact resistance, oxidation and breaks
3Follow the signal ground wire to the pump and look for a break with a multimeter
4If you have a diagnostic tool: see whether the code is active now or only stored, and when it last occurred
5If the fault remains, have a workshop check the LIN communication to the coolant pump

Symptome, die Sie bemerken können1

Temperature control works unevenly

Was der Fehler beeinflussen kann1

The coolant pump runs at full speed
