Check Engine Light Diagnostic Service

Is Your Toyota's Check Engine Light On?

No matter the make or model of Toyota owned, there is nothing more alarming than driving around Whitestown, IN area and seeing the check engine light illuminated on the dashboard display. Modern-day vehicles are comprised of interrelated systems of great complexity. Computerized systems onboard the vehicle work in tandem with other critical engine components of the vehicle to monitor performance and signal the driver if the vehicle discontinues working within normal operations. This signal is one that requires immediate action or can result in being stranded on the side of the road and potentially high repair costs if left unchecked.

Diagnosing Your Illuminated Check Engine Light

At Tom Wood Toyota, our certified and factory-trained technicians use state-of-the-art technology and tools to conduct the proper diagnostic procedures when the check engine light is illuminated that includes several steps:

  • Data retrieval - to collect critical data relating to the vehicle's performance, a multi-function scanning tool is used by the service technician to analyze the onboard computer system to retrieve data that includes freeze-frame, various computer codes, sensor data, software version numbers and other status data that will help to identify what triggered the illumination of the check engine light.
  • Verification - this test will help to determine if all critical systems are functioning within their expected specifications and includes the analysis of the ignition, emissions and fuel system, electrical and mechanical engine timing, backpressure and engine vacuum. A failure of these systems will result in the illumination of the check engine light.
  • Pinpoint - this testing is required by all manufacturers to ensure diagnostic testing that includes a visual inspection of specified areas, bi-directional control tests and analyzing wiring diagrams.
  • Verification / Repairs - after the completion of all tests, an additional round of testing is completed to determine if replacement of parts is repairs are required.
