Component Inspection

Check CKPS.
1. Key "ON". (Don't disconnect sensors.)
2. Select "vehicle scope meter" in the menu, and connect channel A of scan tool with terminal 1 of CKPS harness connector.
3. Engine start. And check the signal waveforms.

4. Is the measured signal waveform O.K?
  YES
  - Go to step 2.
  NO
  - Substitute with a known-good CKPS and check for proper operation.
  - If the problem is corrected, replace CKPS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check ECM/PCM.
1. IG "OFF".
2. Connect scan tool and Engine "ON".
3. Select simulation function on scan tool.
4. Simulate frequency (Hz) at terminal 1 of CKPS signal connector.

5. Does the signal value of CKPS change according to simulation frequency?
  YES
  - Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NO
  - Substitute with a known-good ECM/PCM and check for proper operation.
  - If the problem is corrected, replace ECM/PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by ECM/PCM.
  Before or after testing ECM/PCM on the vehicle, use this function to reuse the ECM/PCM
