Advanced Diagnostics & Electrical Repair in Des Moines, IA
More Than Just Reading Codes
Today’s vehicles contain dozens of computer modules constantly monitoring performance and safety. When something goes wrong, these systems generate trouble codes, but codes alone don’t tell the whole story.
Professional diagnostics can:
- Save you money by pinpointing the true source before replacing parts
- Prevent bigger problems by catching issues early before they cause breakdowns
- Improve safety by confirming critical systems are working properly
We don’t guess, and we don’t throw parts at problems. We diagnose carefully, explain what we find, and recommend solutions that work.
Common Issues We Catch Before They Become Breakdowns
Check Engine Lights
From loose gas caps to failing sensors, we identify what triggered your warning light.
Wiring Issues
Flickering lights, power accessory failures, or intermittent problems traced through complex wiring.
Electrical System Faults
Dead batteries, alternator problems, or mysterious drains. We find the real issue.
Module Communication Problems
Multiple warning lights often indicate network faults. We identify failing modules.
Starting Problems
When your vehicle won't start or cranks slowly, we diagnose the battery, starter, or electrical system.
Safety System Alerts
ABS or airbag warnings require proper diagnosis to restore safe operation.
Sensor Failures
When sensors fail or send incorrect data, performance suffers. We diagnose and replace faulty components.
Complete Diagnostic and Electrical Solutions
Advanced Computer Diagnostics
Using professional-grade Autel scanners, we access all vehicle systems to read trouble codes, view live data streams, and perform comprehensive system tests. This advanced equipment goes far beyond basic code readers to provide the detailed information needed for accurate diagnoses.
Electrical System Testing and Repair
We test and repair batteries, alternators, starters, and charging systems to ensure proper electrical function. Our testing identifies whether you need a simple battery replacement or if underlying issues are affecting your vehicle's electrical performance.
Circuit and Wiring Diagnostics
Our technicians trace electrical problems through complex wiring systems to identify shorts, open circuits, parasitic drains, and connection issues. We methodically test circuits to find problems that cause frustrating intermittent symptoms.
Sensor Diagnostics and Replacement
We diagnose sensor failures across all vehicle systems, verify proper operation through testing, and replace faulty sensors with quality parts. Proper sensor function is critical for performance, fuel economy, and emissions compliance.
Module Programming and Calibration
When modules need replacement, reprogramming, or calibration, we have the specialized equipment and technical knowledge to complete the work properly and ensure all systems communicate correctly.
Check Engine Light Diagnostics
We don't just read the code. We interpret what it means, test related systems to verify the diagnosis, and identify the true source of the problem so you can move forward with confidence and accurate repair information.
Electrical Accessory Repair
From power windows and door locks to lighting systems and convenience features, we diagnose and repair electrical accessories that make your vehicle functional and comfortable to drive.

Frequently Asked Questions
What does a diagnostic test include?
A diagnostic test includes scanning your vehicle's computer systems for error codes, analyzing live data, and performing targeted tests. We examine engine, transmission, electrical, and safety systems to identify the exact source of issues.
How long does a diagnostic take?
Basic diagnostic scans typically take 30 minutes to an hour. Complex electrical issues may require additional testing time. We provide realistic estimates and keep you informed throughout.
Can you diagnose intermittent electrical problems?
Yes. Our Autel scanners can monitor systems over time and record data when problems occur. Combined with systematic testing, we identify causes even when symptoms come and go.
