Co oznacza ten kod błędu?
The DC/DC converter control module has at some point registered that the temperature of the converter's transformer was outside the permitted range, in the circuit for temperature sensor B. The fault is intermittent, meaning it is sporadic: it has occurred but may not be present right now. A faulty temperature sensor, a cooling system that is not working, or a break or short in the connections can be behind it.
Możliwe przyczyny
- Faulty function of temperature sensor B
- Faulty cooling of the converter
- Break or short circuit in the connections
Co możesz zrobić
- 1Switch the ignition off, wait a moment and switch it on again. If the warning clears and does not return, the fault may have been temporary
- 2Note whether the warning behaves differently when the car is cold compared with when it is warm
- 3Have a workshop check temperature sensor B and its connections with diagnostic equipment, together with the converter's cooling
- 4The high voltage system may only be handled by qualified personnel, so leave the converter's cooling and wiring to them
Objawy, które możesz zauważyć4
- Warning symbol and message that come and go in the display
- Charging of the high voltage battery is absent or reduced while driving at times
- The high voltage battery discharges or charges poorly
- Hybrid mode is forced and the combustion engine runs too often
