Advanced Diagnostic Technology for Accurate Results

Our diagnostic equipment can identify issues before they become major problems, saving you time and money.

Serious Diagnostics for Serious Equipment

Modern trucks rely on electronic control modules to manage everything from engine timing to emissions and safety systems. Our computer diagnostics service helps pinpoint root causes—whether it's a performance drop, a check engine light, or a regen issue—using OEM software and dealer-level scan tools.

Testing Matched to the Vehicle

We use diagnostic information and equipment-appropriate testing to investigate engine, electrical, and aftertreatment concerns. Available functions vary by vehicle, system, and software. Contact us with the VIN and engine details to discuss the scope before scheduling.

What Diagnosis Can Establish

A scan retrieves information reported by control systems. Finding the cause may also require circuit checks, measurements, inspection, or observing the symptom under appropriate conditions. A code description is not an instruction to replace the component it mentions. Intermittent faults may need a detailed history when they are not present in the shop.

Agree on the initial scope and approval contact. Tell us if codes were cleared, batteries disconnected, or parts replaced before the visit. Keeping those changes visible helps prevent a new test result from being mistaken for the vehicle’s original condition.

Frequently Asked Questions

What does a computer diagnostic do?

Computer diagnostic services involve scanning various components of a vehicle's electronic systems to identify any underlying issues or malfunctions that may be occurring, which could cause trouble down the road if left unchecked.
The primary purpose of this is to detect potential problems early on before they become more severe or costly repairs later on down the line, thus saving time & money while also improving the overall safety & reliability of the vehicle.

How much does computer diagnostic testing cost?

The scope depends on the vehicle, symptoms, and testing required. Contact us with the equipment details to discuss the initial diagnostic work and approval process. A code scan alone may not establish the cause.

Are there any signs I should look out for that indicate my vehicle might need computer diagnostic testing?

Several common signs may indicate that your rig might need some form of computer diagnostic testing, such as: decreased fuel economy, difficulty starting, difficulty driving, excessive exhaust smoke, strange noises coming from mechanical systems, increased emissions levels, or unexplained vibrations coming from underneath the hood area. If any of these symptoms are present, check them out sooner rather than later before further damage occurs!

Do all diagnostic tools work the same for every truck?

No, not all diagnostic tools are created equal. Many systems require OEM-specific software to access advanced functions like forced regens, parameter resets, or programming. Generic scan tools may only read basic fault codes. At our shop, we use OEM diagnostic software to ensure full system access and accurate repairs across all major truck and reefer brands.
