Component Inspection

ETC Motor Inspection
1. Visually/physically inspect the restriction or any foreign objects in throttle body.
2. Clean or replace as necessary and go to VERIFICATION OF VEHICLE REPAIR .
  If OK, go to next step as below.
3. Ignition "OFF".
4. Disconnect the ETC motor harness connector.
5. Measure resistance between 'ETC output 1' terminal and 'ETC output 2' terminal of ETC motor harness connector.
  (Component side)
  
  Specification: 1.2~1.8 Ω at 20°C (68°F)

6. Is resistance within specification?
  YES
  - Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to VERIFICATION OF VEHICLE REPAIR .
  NO
  - Substitute with a known-good switch and check for proper operation. If the problem is corrected, replace component and then go to VERIFICATION OF VEHICLE REPAIR .
    NOTE:
    It is necessary to perform the TPS adaptation procedure after the ETC assembly or PCM replacing.
    
    TPS adaptation procedure
    
    Ignition "OFF" and then "ON" without cranking. Wait for 10 seconds under enable conditions.
    → Enable conditions: Battery > 10 V & Intake Air Temp. > 5.3°C (41.5°F) & 5.3°C (41.5°F) < Engine Coolant Temp. < 905 of 1103
