Hva betyr feilkoden?
The DC/DC converter control module has registered that the signal from temperature sensor A is erratic, meaning the reading jumps around and is not stable. The fault is generic and gives no further detail on its type. The cooling system may be at fault, as may the temperature sensor in the control module. Charging of the high voltage battery is affected.
Mulige årsaker
- Faulty temperature sensor in the DC/DC converter control module
- Faulty cooling system for the converter
Hva du kan gjøre
- 1Switch the ignition off, wait a moment and switch it on again, and check whether the warning goes out
- 2Check the cooling system for visible leaks and make sure the coolant level is correct
- 3Have a workshop check the temperature sensor and its circuit with diagnostic equipment, since erratic readings can come from poor contact
- 4Work on the converter's cooling or wiring is reserved for qualified high voltage personnel
Symptomer du kan merke4
- Warning symbol and message in the display
- Charging of the high voltage battery is uneven or absent while driving
- The high voltage battery discharges or charges poorly
- Drive modes PURE, SAVE and AWD disengage automatically or are not available
Hva feilen kan påvirke2
- No charging of the high voltage battery
- Hybrid drive mode is forced
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
