3. 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 
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.  

4. If diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool instruction.  

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 - F150 PICKUP .  

z

NO RESP/NOT EQUIP for Generic Electronic Module (GEM) or Central Timer Module (CTM), 
go to Pinpoint Test A.  

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.  

6. If the DTCs retrieved are related to the concern, go to the GEM/CTM DIAGNOSTIC TROUBLE 

CODE (DTC) INDEX to continue diagnostics.
