When your check engine light comes on, your vehicle starts running rough, or something just doesn’t feel right, guessing can get expensive fast. At Crompton Brothers Automotive, we provide accurate, professional vehicle diagnostics in Burnaby to identify the real cause of the problem — so you can repair it correctly the first time.
Serving Burnaby since 1980, we help drivers and local businesses get clear answers and dependable solutions. Whether it’s an intermittent warning light, poor performance, an electrical issue, or a no-start problem, our technicians use proven diagnostic processes and modern equipment to pinpoint the issue and explain your best options.
Vehicle diagnostics is the process of testing your vehicle’s systems to identify why a warning light is on, why performance has changed, or why a component is failing. Modern vehicles rely on sensors, modules, and computer-controlled systems. When something is off, the vehicle stores information (fault codes and data) that helps determine what’s happening.
A proper diagnostic isn’t just plugging in a scanner and reading a code. Codes are clues — the real job is identifying the root cause behind the symptom.
If you notice any of the following, it’s time to book diagnostic testing:
