Co oznacza ten kod błędu?
The television module (TVM) checks antenna 4. The code is set when the voltage is too high, because the cable between the antenna and the TV module has contact with voltage. The antenna signal can then degrade so that the TV picture becomes poor.
Możliwe przyczyny
- Short circuit to voltage in the wire that links antenna 4 with the Television Module (TVM)
Co możesz zrobić
- 1Check that the fuses for the TV system are intact.
- 2Read off the code, clear it and test-drive the TV function to see whether it returns.
- 3Look for chafing and pinched areas on the cable to antenna 4, especially where it runs close to other cables.
- 4With a multimeter you can check that the cable has no contact with battery voltage.
- 5If you have a diagnostic tool: watch antenna 4 in live data and see whether the voltage reads too high while the TV function is in use.
- 6If the fault remains after these checks, have a workshop check the antenna and the cable.
