Inspection and Verification - Electronic Shift





1. Visually inspect for the following obvious signs of mechanical and electrical damage.
2. If the concern remains after the inspection, connect the scan tool to the Data Link Connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the scan tool menu. If the scan tool 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.
3. If the scan tool still does not communicate with the vehicle, refer to the scan tool manual.
4. Carry out the DATA LINK DIAGNOSTICS test. If the scan tool responds with:
^ CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Module Communications Network.
^ NO RESP/NOT EQUIP for 4WD control module, go to Pinpoint Test B. Test B: No Communication With 4WD Control Module
^ SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and carry out the 4WD control module self-test.
5. If the DTCs retrieved are related to the concern, go to the 4WD Control Module Diagnostic Trouble Code (DTC) Index to continue diagnostics.
6. If no DTCs related to the concern are retrieved, carry out the Electronic Shift Function Test. Test A: Electronic Shift Functional Test
