  • Check IATS resistance 
    1. Ignition "OFF" and disconnect IATS connector.
    2. Measure resistance between signal and ground terminals of IATS connector after checking out the temperature of IATS with GDS (Component Side)

      Specification: 

      TEMPERATURE AND RESISTANCE CHART

      Temp. (°C) Resistance (kΩ)
      -40 (-40°F) 95.95 ~ 105.78
      -20 (-4°F) 27.4 ~ 29.77
      0 (32°F) 9.08 ~ 9.72
      10 (50°F) 5.49 ~ 5.83
      20 (68°F) 3.42 ~ 3.61
      40 (104°F) 1.43 ~ 1.5
      60 (140°F) 0.66 ~ 0.69

    3. Is the measured resistance within specification?

      YES 

      • Substitute with a known-good ECM and check for proper operation. If the problem is corrected, replace ECM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
        NOTE: There is a memory reset function on GDS that can erase optional parts automatically detected and memorized by ECM. Before or after testing ECM on the vehicle, use this function to reuse the ECM on the others

      NO 

      • Substitute with a known-good IATS and check for proper operation. If the problem is corrected, replace IATS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

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.
