Component Inspection

1. Check CCV
(1) Ignition "OFF"
(2) Measure resistance between power and control terminals of the CCV connector.
A. Specification : Approx. 15.5 - 18.5 Ohms (20 °C (68 °F))




(3) Is the measured resistance within specification ?
YES
1) 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
1) Substitute with a known - good CCV and check for proper operation.
If the problem is corrected, replace CCV and go to "Verification of Vehicle Repair" procedure.

NOTE: There is a memory reset function on scantool that can erase optional parts automatically detected and memorized by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others
