If the scan tool responds with:
- CKT914, CKT915 or CKT7O = ALL ECUS NO RES P/NOT EQUIP, refer to Module Communications Network (Information Bus).
- NO RES P/NOT EQUIP for generic electronic module (GEM), go to Pinpoint Test U. Test U: No Communication With Module- Generic Electronic Module
- SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the GEM/CTM.
7. If the DTCs retrieved are related to the concern, go to the GEM/CTM Diagnostic Trouble Code (DTC) Index to continue diagnostics. GEM/CTM Diagnostic Trouble Code (DTC) Index
