Component Inspection

■ Check ECTS resistance 

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

    Specification: 

    Temp. (°C) Resistance (kΩ) Temp. (°C) Resistance (kΩ)
    -40 48.14 40 1.15
    -20 14.13 ~ 16.83 60 0.59
    0 5.79 80 0.32

  3. Is the measured resistance within specification?

    YES 

    • Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "Verification of Vehicle Repair " procedure.

    NO 

    • Substitute with a known - good ECTS and check for proper operation. If the problem is corrected, replace ECTS and go to "Verification of Vehicle Repair " procedure.
