Electronic diagnostics of automatic transmission
Automatic Transmission Electronic Diagnostics (ETD) is the process of using electronic tools and software to identify problems with the operation of the automatic transmission. This diagnostic allows you to accurately determine the malfunction and eliminate it with minimal time and money.
Electronic diagnostic methods for automatic transmissions
* Reading and analysis of trouble codes (DTC). Trouble codes are stored in the electronic transmission control module (TCM) and indicate specific malfunctions in the system.
* Checking automatic transmission parameters. Using a diagnostic scanner, you can check various automatic transmission operating parameters, such as:
*Transmission system pressure
* Working fluid temperature
* Gear ratios
* Automatic transmission solenoids
* Analysis of data from an oscilloscope. An oscilloscope measures the electrical signals in the automatic transmission and can identify problems with wiring, solenoids or sensors.
* Real-time feedback. The diagnostic scanner allows you to communicate with the TCM in real time, which makes it possible to monitor the operation of the automatic transmission in real time and identify malfunctions as they occur.
The benefits of electronic automatic transmission diagnostics
* Accurate fault detection. Electronic diagnostics allows you to accurately determine the cause of an automatic transmission malfunction, without the need to disassemble and inspect the components.
* Quickly detect problems. Modern diagnostic tools can quickly detect problems and fix them before they cause serious problems.
* Cost reduction. Accurate identification of the malfunction allows it to be eliminated at minimal cost, since it eliminates the need for expensive trial-and-error repairs.
* Increased service life of automatic transmission. Regular electronic automatic transmission diagnostics allows you to detect and eliminate minor faults, preventing them from developing into more serious problems and extending the life of the gearbox.
