Is the above items normal ?
 | ▶ Go to "Check CKPS resistance" as follows. |
 | ▶ Repair or replace it, and go to "Verification of Vehicle Repair" procedure. |
IG "OFF"
Check CKPS and target wheel for deformation or damage visually
Is the above items normal ?
| ▶ Go to "Check CKPS resistance" as follows. |
| ▶ Repair or replace it, and go to "Verification of Vehicle Repair" procedure. |
IG "OFF" and disconnect CKPS connector.
Measure resistance between low signal and high signal terminals of CKPS connector.(Component side)
Specifiation : 774 ~ 946Ω [20℃(68℉)]
Is the measured siganl waveform normal?
| ▶ Go to "Check signal waveform of CKPS" as follows. |
| ▶ 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. |
IG "OFF" and connect scantool.
ENG "ON" and Measure signal waveform at signal terminal of CKPS.
Fig.1) Normal waveforms of CKPS & CMPS
Is the measured siganl waveform normal?
| ▶ 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. |
| ▶ 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 scantool that can erase optional parts automaticallydetected and memorized by ECM. Before or after testing ECM on the vehicle, use this function to reuse the ECM on the others |
