Computer diagnostics of automatic transmission transmission
Computer diagnostics of an automatic transmission (AT) is the process of reading and analyzing data from the electronic transmission control module (TCM) or transmission control module (TCM). This data may include information about:
* Fault codes
* Sensors
* Solenoids
* Fluid pressure
*Transmission temperature
The automatic transmission computer diagnostic procedure usually includes the following steps:
1. Connecting a diagnostic scanner: The diagnostic scanner is connected to the OBD-II diagnostic connector of the vehicle.
2. Reading Trouble Codes: The scan tool reads and displays trouble codes that are stored in the TCM.
3. Data Analysis: The data read from the scanner is analyzed to determine the faulty component or system.
4. System check: Once a fault has been identified, additional checks can be carried out to confirm the diagnosis. These may include:
*Checking automatic transmission fluid
* Checking solenoids
* Checking sensors
5. Reset fault codes: After checking and correcting the fault, the fault codes are reset.
Advantages of computer automatic transmission diagnostics:
* Accurate fault identification
* Fast and effective diagnosis
* Ability to prevent further damage
* Assistance in planning repairs
When should computer diagnostics of an automatic transmission be carried out:
*If the transmission fault light comes on
*If the transmission does not shift smoothly
*If the transmission slips or vibrates
*If there are automatic transmission fluid leaks
*With regular maintenance
Regular automatic transmission computer diagnostics can help identify and correct problems early, preventing costly repairs or replacements.
