Commercial Truck Diagnostics that start with the Problem

A fault code is a clue, not always the failed part. Diesel Rescue reviews the symptoms and available truck information, performs the appropriate inspection or testing, explains what was found, and discusses the next step before additional work is performed.

1. Tell us what changed

Describe the warning light, noise, smell, performance issue, or starting problem.

2. Inspect and diagnose

The technician evaluates the truck using the appropriate inspection and diagnostic process.

3. Explain the findings

Understand what was found and what options may be available.

4. Plan the repair

Decide on the next step based on safety, urgency, and the truck’s needs.

Maintenance Support for
Owner-Operators and Fleets
