- Disconnect information center 20-pin connector. Using external ohmmeter, measure resistance between ground and terminals No. 14, 15, 17, 18 and 19. If resistance is less than 200 ohms on any circuit, go to next step. If resistance is 200 ohms or greater on any circuit, replace information center.
- Disconnect transfer case switch. Switch is located on top left side of transfer case. Using external ohmmeter, measure resistance between ground and terminals No. 14, 15, 17, 18 and 19. If resistance is less than 200 ohms on any circuit, repair appropriate circuit for short to ground. If resistance is 200 ohms or greater on any circuit, replace transfer case switch.
