So there's something not quite right about the way your vehicle is driving, or you've got a warning light on your dashboard that was blinking at you yesterday and now it is on steady. What do you do? Hint: the answer is not to put a piece of electrical tape over the warning light and ignore it.
Some of the potential causes for a check warning light are not properly tightening your gas cap to engine, transmission or braking system performance issues. While warning lights can go on and the car still appears to be driving "fine", ignoring some lights can lead to serious issues, such as engine damage or other component failure. In some instances, this can be a safety hazard. That's why it is recommended to be safe (give yourself peace of mind) and have your car looked at by a certified professional as soon as possible.
NOTE: Merely “pulling codes” does not generally provide enough information to make an accurate diagnosis of the problem. Pulling codes is the initial step in the process by identifying the circuit or system that has illuminated the vehicle’s check engine light.
2. VERIFICATION TESTING - Verification tests determine if systems meet proper specifications. These tests may include an analysis of:
NOTE: Failure in any of these basic systems can cause the check engine light to illuminate and falsely identify a circuit or component as the problem, which could lead to improper or unnecessary parts replacement.
3. PINPOINT TESTING - All manufacturers require that circuit or component pinpoint testing is done in order to make an absolute diagnostic determination. These actions involve:
4. RESEARCH TECHNICAL SERVICE BULLETINS - Technical Service Bulletins and hotline information will indicate if the problem has been determined to be a pattern failure, meaning that it is a known issue that occurs with a particular type of vehicle. This does not eliminate the need for testing, as other systems must meet specifications before a service bulletin procedure should be performed.
5. CAR REPAIR - This may involve multiple actions such as:
6. VERIFY REPAIR - Once all necessary actions have been taken, the vehicle must be retested to verify that the repair is complete and has achieved the proper results.
