What does this fault code mean?
The code is named low fluid level, but the condition concerns the signal wire to the coolant pump, which is shorted or has a break, or another fault in the pump that prevents cooling.
Possible causes
- Damaged pump
- Short circuit or break in the wiring to the pump
What you can do
- 1Check the coolant level when the engine is cold, as the code is named for a low fluid level
- 2Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
- 3Read off the fault code with the ignition on and check whether it is still active
- 4Have a workshop check the pump and its wiring, as cooling of the hybrid system is a workshop task
- 5Do not work on the hybrid system's wiring yourself
Symptoms you may notice2
