Co oznacza ten kod błędu?
Although the code is named desired engine speed signal, it applies when the speed signal from the transmission control module (TCM) is faulty. The TCM sends a fault message to the engine control module (ECM), which stores a code, while the code for the speed sensor signal is stored in the TCM. The cause should therefore be looked for in the transmission control module.
Możliwe przyczyny
- Fault in the transmission control module (TCM)
- Fault in the speed sensor signal to the transmission control module (TCM)
Co możesz zrobić
- 1Read off the trouble codes in the transmission control module (TCM) and remedy them first, as the code in the engine control module is a following fault
- 2Clear the code in the engine control module only once the root fault in the transmission control module has been remedied and its trouble code has been cleared
- 3Check that the connectors to the transmission control module are secure and free from oxidation
- 4If you have a diagnostic tool: compare the speed value in the transmission control module's live data with the speedometer during a test drive
