Component Inspection

Component Inspection

1. Check Ignition Coil
(1) IG "OFF" and disconnect ignition coil connector.
(2) Measure resistance between terminals 1 and 2 of ignition coil connector. (Component side)
(3) Measure resistance between terminal 1 of ignition coil connector and output terminal of secondary ignition coil.
A. Specification :













(4) 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 Ignition Coil and check for proper operation.
- If the problem is corrected, replace Ignition Coil and go to "Verification of Vehicle Repair" procedure.

CAUTION:
There is a memory reset function on scantool that can erase optional components automatically detected and memorized by PCM.Before or after testing PCM on the vehicle, use this function to reuse the PCM.
