Maintenance Light/Check Engine Light On

On-site diagnosis of maintenance alerts and check engine warning lights using manufacturer-specific diagnostic software and specialty communication adapters. We access control modules, retrieve fault codes, review live data, and perform system tests in accordance with OEM diagnostic procedures.

 

This service is designed to accurately identify the cause of warning indicators on heavy equipment and diesel-powered machinery, allowing for informed repair or maintenance recommendations based on manufacturer data rather than generic scan results.
