NOTE:
  • Navigate to Inspection Mode for measuring Exhaust Gas  . Ref. to P-HEV HYBRID POWERTRAIN CONTROL (DIAGNOSTICS)>WORK SUPPORT>OPERATION>SERVICE MODE .
  • If it is necessary to run the engine for 10 minutes or more, fasten the driver's seat belt  .
  • After engine is warmed up, attach the check board for measurement  .
  • Place the select lever in "P" range or "N" range  .
  • Turn the A/C to OFF  .
  • Turn all the accessory switches to OFF  .
  • Waveforms vary depending on a measurement environment and vehicle condition  .
  • Oscilloscope waveform illustrated here is an example for reference. Noise and chattering in waveform are omitted  .

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.
