Toyota Loyalty Diagnosis


If you've ever driven a vehicle then you have probably had the check engine light show up on your dashboard. For many people, this can seem like a scary, unknown signal. Do not fear, the certified and master service technicians at Walla Walla Toyota are a quick pit stop away from clearing your dash of those annoying signals. When your check engine light comes on, that means it is time for a quick diagnostic test at your local Toyota dealership.


All vehicles run on and are monitored by a computer, with an average of 60-100 internal sensors located throughout the vehicle. The computer communicates with all the internal sensors of the car and most of the electronic components inside your vehicle. If the computer registers an abnormal read or detects that one of the sensors is not functioning properly, it marks an "error code" in its data log and turns on your vehicle's check engine light.


If your check engine light comes on, a simple diagnostic test will reveal what is going wrong with your vehicle. To perform the diagnostic test, a scanner is plugged into your vehicle's OBD-II port (all vehicles manufactured in the United States after 1995 are fitted with this system). The scanner reads your car's computer log of "trouble codes" to figure out where the problem is. The trouble codes are a list of all the abnormalities picked up by the internal sensors. Trouble codes are categorized by 3 names; Powertrain, Body, or Chassis. Here at Walla Walla Toyota, one of our certified technicians can interpret these trouble codes, give you an experience run-down of all the information gathered in the diagnostic test, and help you come up with a service plan to resolve the issue.
