What does this fault code mean?
Although the fault is named temperature sensor, it concerns the internal components of the display, which the module checks. The fault code is set when any of them does not work, and the cause is a damaged module. The front display then does not work.
Possible causes
- Damaged front display module (HLDF)
What you can do
- 1Clear the fault code and start the car to see whether it returns
- 2Check that the connectors to the display module are secure and free from oxidation
- 3If the fault code returns, have a workshop replace the front display module
