Kool2U uses the trouble code as the starting point and performs additional testing as required.

• Electronic modules
• Network communication
• Computer controlled charging systems
• Electronic steering
• Transmission controls
• Engine management systems

​

Problems Other Shops Have Not Been Able to Diagnose

Some vehicle problems are straightforward.

Others are intermittent or involve several systems simultaneously.

Kool2U frequently works with customers whose vehicle has already had parts replaced but the original problem remains.

Our diagnostics-first approach is designed to answer:

What is actually causing the problem?

rather than: What part can we replace next?
