Was bedeutet der Fehlercode?
Both high voltage circuits have their own safety circuit, known as an interlock, which checks that components, cables and connectors are correctly connected. The code is set when the level of the safety circuit is too low. The fault may be in the manual service disconnect, a short to ground in the circuit, or one of the connected modules.
Mögliche Ursachen
- The manual service disconnect (MSD) is damaged
- The base for the manual service disconnect (MSD) is damaged
- The interlock circuit is short-circuited to ground
- The Inverter System Controller (ISC) is damaged
- The Air Conditioning Compressor Module (ACCM) is damaged
Was Sie tun können
- 1Read and note the fault code, clear it and road test to check whether it returns
- 2Have a workshop check visible damage to the high voltage cable sheathing, such as chafing or pinch marks
- 3Have a workshop check that the manual service disconnect is fully in place and undamaged
- 4The high voltage system should only be handled by qualified personnel, so have a workshop carry out all work on the battery and other high voltage parts
Symptome, die Sie bemerken können4
- Red warning symbol and message in the display
- Charging of the high voltage battery stops or works poorly
- Drive modes PURE, SAVE and AWD disengage automatically or cannot be selected
- The combustion engine runs more often than normal in HYBRID mode
Was der Fehler beeinflussen kann3
