Co oznacza ten kod błędu?
The control module has noticed that the gear ratio stays the same when clutch C4 ought to have released. The fault may come from linear pressure solenoid SL4 sticking, but other parts of the transmission can also cause it. If the clutch does not disengage correctly the gear change is aborted, to prevent damage to the clutches and brakes.
Możliwe przyczyny
- Wrong adaptation values held in the TCM memory
- Contact resistance, oxidation or poor connection at the SL4 connector or joint
- SL4 is stuck or damaged
- Clutch C4 is damaged
- Poor transmission fluid quality
- Mechanical fault or internal fault in the transmission control system or in the TCM
Co możesz zrobić
- 1Read all transmission codes and deal with any other transmission codes first, as they may be the root cause
- 2Check the transmission oil level and the condition of the oil, and look for oil leaks
- 3Check that the battery is in good condition and that the fuses are intact
- 4If the fault returns, have a workshop reset the adaptation and check SL4 and clutch C4, and replace the mechatronic unit if needed
