4. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
5. Carry out the DATA LINK DIAGNOSTIC TEST. If the diagnostic tool responds with:
z
CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to MODULE
COMMUNICATIONS NETWORK .
z
NO RESP/NOT EQUIP for GEM/CTM, go to Pinpoint Test A.
z
NO RESP/NOT EQUIP for RCM, refer to AIR BAG RESTRAINT SYSTEMS - F150 PICKUP .
z
SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the
continuous DTCs and carry out self-test diagnostics for the RCM, GEM or CTM.
6. If the DTCs retrieved are related to the concern, go to GEM/CTM Module Diagnostic Trouble Code
(DTC) Index to continue diagnostics.
