4. If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC)
located beneath the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If
the diagnostic tool does not communicate with the vehicle:
z
check that the program card is correctly installed.
z
check the connections to the vehicle.
z
check the ignition switch position.
5. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool instruction.
6. 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 - F150 .
z
NO RESP/NOT EQUIP for GEM/CTM, go to PINPOINT TEST G: NO COMMUNICATION
WITH MODULE .
z
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.
8. If no DTCs related to the concern are retrieved, proceed toSymptom Chart to continue diagnostics.
