Visual Inspection Chart
2. Visually inspect for obvious signs of mechanical and electrical damage.
3. If the concern remains after the inspection, connect the WDS or equivalent Tester to the data link connector (DLC) located beneath the instrument
panel and select the vehicle to be tested from the WDS or equivalent Tester menu. If the WDS or equivalent Tester does not communicate with the
vehicle:
-
check that the program card is correctly installed.
-
check the connections to the vehicle.
-
check the ignition switch position.
4. If the WDS or equivalent Tester still does not communicate with the vehicle, refer to the WDS or equivalent Tester manual.
5. Carry out the DATA LINK DIAGNOSTICS test. If the WDS or equivalent Tester responds with:
-
CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to COMMUNICATIONS NETWORK.
-
NO RESP/NOT EQUIPPED for generic electronic module (GEM), go to Pinpoint Test 1.
-
SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test
diagnostics for the GEM.
6. If the DTCs retrieved are related to the concern, go to the GEM Diagnostic Trouble Code (DTC) Index to continue diagnostics. See: Diagnostic
Trouble Code Descriptions/Multifunction Electronic Module/Trouble Code Descriptions
7. If no DTCs related to the concern are retrieved, refer to the continue diagnostics.
