What does this fault code mean?
The temperature difference between parts of the battery has become too large, which indicates that cooling works worse than it should. It may be a consequential fault of another fault, or the cooling loop inside the battery may be blocked.
Possible causes
- Consequential fault to a fault showing reduced cooling
- The coolant circuit within the battery pack is obstructed or the battery is damaged
What you can do
- 1Read and note the fault code, clear it and road test to check whether it returns
- 2Make sure the coolant level in the battery cooling loop is high enough and top up if needed
- 3Have a workshop check whether other temperature related fault codes are stored in the BECM and remedy them first
- 4Have a workshop check the battery cooling. If the cooling loop is blocked, the battery may need replacing
- 5The 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
