Perkins EST Electronic Service Tool 2024A

Perkins EST 2024A Overview, Compatibility, and Best Adapters

What is Perkins EST 2024A?

Perkins EST (Electronic Service Tool) 2024A is official dealer-level diagnostic software used for troubleshooting, programming, and calibrating Perkins electronic engines. It is similar to Caterpillar ET but specifically designed for Perkins engines, allowing access to ECMs (Electronic Control Modules) to read fault codes, adjust parameters, and perform software updates.

Since Perkins is a subsidiary of Caterpillar, EST also shares some compatibility with CAT engines that use Perkins-derived platforms.
