Hva betyr feilkoden?
The DC/DC converter control module has registered a fault in the circuit for temperature sensor B. The fault is generic and gives no further detail. The causes may be a faulty temperature sensor, a cooling system that is not working, or a break or short in the connections. Because the converter is part of the high voltage system, charging of the high voltage battery is affected.
Mulige årsaker
- Faulty temperature sensor B in the DC/DC converter control module
- Faulty cooling system for the converter
- Break or short circuit in the connections
Hva du kan gjøre
- 1Switch the ignition off and on again, and see whether the code comes back
- 2Check that the cooling system has no leaks and that the coolant level is correct
- 3Have a workshop check the connections to temperature sensor B and the cooling system for breaks, contact resistance and oxidation
- 4Work on the converter's wiring or connections is for qualified high voltage personnel only. Do not attempt it yourself
Symptomer du kan merke4
- Message and warning symbol in the display
- Charging of the high voltage battery is absent or reduced while driving
- The high voltage battery discharges or charges poorly
- Drive modes PURE, SAVE and AWD disengage automatically or cannot be selected
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.
