If difficulty occurs when shifting transfer range with engine running, perform Engine Idle Speed Adjustment prior to troubleshooting drivetrain. If engine was turned OFF in order to shift transfer to desired range, notify DS maintenance. For the vehicle not to move, there must be a major problem in the drivetrain. If you've already run the transmission tests, and you still can't find the problem, continue down this test chain. Lube in accordance with table 2-1.
