Diagnostic Tests: Notes

NOTE: On vehicles with NVIS system, all ignition keys to be used with vehicle must be reprogrammed when PCM is replaced. See appropriate ANTI-THEFT SYSTEMS article in ACCESSORIES & EQUIPMENT. Also, IACV-AAC valve idle air volume learning procedure must be performed when PCM is replaced. See ON-VEHICLE ADJUSTMENTS article.
