  1. Ensure 4WD system is operating properly. If system is not operating properly, check and repair as necessary. See appropriate TRANSFER CASES article. If PART TIME indicator light does not operate, go to next step.
  2. Turn ignition on. Check for battery voltage between ground and powered side of fuse No. 10 (10-amp) in fuse box. Fuse box is located behind glove box. If battery voltage exists, go to next step. If battery voltage does not exist, repair open circuit between fuse and ignition switch.
  3. Turn ignition off. Disconnect negative battery cable. Disconnect transfer case switch connector. Switch is located at top of transfer case, between main body and front driveshaft. Check continuity between ground and transfer case switch harness connector terminal "B" (Black wire). If continuity exists, go to next step. If continuity does not exist, repair open circuit.
