Component Inspection

Component Inspection

1. Check VIS #2
(1) IG "OFF" and disconnect VIS #2 connector.
(2) Measure resistance between terminals 1 and 2 of VIS #2 connector. (Component side)
A. Specification : 29 - 35 Ohms (22°C/71.6°F)




(3) 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 VIS #2 and check for proper operation. If the problem is corrected, replace VIS #2 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.
