computer diagnostics

Modern vehicles rely on complex computer systems to monitor performance, safety, and efficiency. When something goes wrong, professional computer diagnostics can pinpoint the issue quickly and accurately. At Toole's Garage, we have access to top-of-the-line diagnostic tools to identify problems in your vehicle’s engine, transmission, electrical system, and more.


Your car’s onboard computer continuously collects data from sensors throughout the vehicle. If a fault is detected, it triggers a warning light and stores an error code. Our skilled mechanics retrieve these codes using specialized diagnostic equipment, analyze the problem, and recommend necessary repairs.


Ignoring warning lights or vehicle performance issues can lead to costly repairs down the road. Whether you’re dealing with an engine misfire, poor fuel efficiency, or electrical malfunctions, Toole's Garage has the tools and expertise to diagnose and resolve the issue efficiently.

When it comes to wheel safety, lug nuts don’t always get the attention they deserve. These critical fasteners are what keep your wheels securely attached to your car, and they need to be tightened to a very specific level of force—known as torque. Get it wrong, and you're risking more than just a loose wheel.

It’s difficult to drive anywhere in the Bay Area and not see a lot of Subaru vehicles. Whether it’s the Subaru Crosstrek, WRX, Outback, Forester, or Ascend, Subaru vehicles are everywhere. At Toole’s Garage we are big Subaru fans. Subaru vehicles are built for the great outdoors, and of course California provides plenty of opportunity for on-road and off-road adventures. All wheel drive (AWD) comes standard on many Subaru models, and can provide consistent traction whether you are on a muddy road, or skiing in the Sierras. If a roof rack did not come standard with your model, it’s easy to add. And of course, interior space is pretty generous, especially if you drive an Outback or Ascent – you can stow plenty of camping and hiking gear. At Toole’s Garage we can provide your Subaru with the maintenance it needs to provide you with a reliable ride – wherever your adventures take you. We highly recommend regular oil change – it not only improves performance and extends engine life, but it also allows us to inspect various sub-systems of your Subaru to catch any impending problems (for example, older Subaru models were prone to oil leaks). And if a long summer trip is in the cards, we definitely suggest bringing it in for a checkup. Being a full service auto repair shop, Toole’s Garage can provide your Subaru with routine maintenance services, diagnostics, as well as major repairs. If your Subaru needs new brake pads, has the check engine light “on”, suffers from transmission problems, or needs major engine repairs – we can make your vehicle healthy again. Whether you have owned your Subaru for a long time, or have recently acquired one, bring it to our San Carlos auto repair shop – we will keep your vehicle in peak condition. Call us to make an appointment, or you can make an appointment online, on our website.
