(1) For type A DTCs, Malfunction Indicator Light (MIL) illuminates as soon as fault is detected. For type B DTCs, MIL is illuminated after 2 consecutive trips where fault is recognized. For type C DTCs, non-emissions related DTCs will cause MIL to flash as soon as fault is detected. For type D DTCs, non-emissions related DTCs will not illuminate or flash MIL.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
