Unified Diagnostic Services

Unified Diagnostic Services (UDS) is like a doctor's check-up for cars. When your car has a problem, mechanics use UDS to do a test and find out what's wrong.

UDS is a set of rules and standards that help mechanics communicate with your car. They use a special tool called a diagnostic scanner that connects to your car's computer. The scanner talks to the car using UDS language and asks it lots of questions about how it's feeling.

The car responds with information about what parts are working and what might need fixing. The mechanic can then use this information to figure out what's wrong and come up with a plan to fix it.

UDS is like a special language that the diagnostic scanner and the car use to communicate with each other. It helps the mechanic understand the car's condition and what needs to be done to keep it running smoothly.
