    • Hublocks
      • installed
      • correct type
    • Central junction box (CJB) fuse 59 (30A)
    • Central junction box (CJB) fuse 27 (15A), 34 (10A)
    • Axle shafts and universal joints
    		  
    • Driveshaft and universal joints
    • 4WD control module (GEM)
    • Shift linkage
    • Fluid leaks
    • Pulse vacuum hublock (PVH) solenoid
    • Matching tire size
    • Wiring harness
    • Vacuum harness
    • Mode select switch (MSS)
    • Gearmotor encoder assembly
    • Connector(s)
    • Shift relays
    • Circuitry
  2. 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:
    • check that the program card is correctly installed.
    • check the connections to the vehicle.
    • check the ignition switch position.
  3. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
    4. NOTE: Make sure that the 4WD control module (GEM) is selected before attempting to carry out an on-demand self-test with the diagnostic tool.
  4. Carry out the DATA LINK DIAGNOSTICS test. If the diagnostic 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 D .
    • 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. Refer to FUNCTION TEST - ELECTRONIC SHIFT  in this section.
