Heat Protection Mode
During very extreme off-road operation, the AWD system utilizes a heat protection mode to protect the ATC solenoid (part of rear axle) from damage. If the system detects an overheat condition, it enters a locked mode. If the heat in the system continues to rise once in the locked mode, the 4X4 control module disables the ATC solenoid. Before continuing with normal operation, allow the system to cool down at least 10 minutes with the ignition switch in the ON position.

General Procedure
Note. Install a new PTU any time the PTU has been submerged in water.
Note. PTU 's equipped with a drain plug are serviceable in the vehicle. They do not require PTU removal.
Note. Do not drain the PTU unless contamination is suspected. To drain the PTU fluid on PTU 's without a drain plug, remove the PTU from the vehicle. The fluid that is drained may appear black and have a pungent odor. Do not mistake this for contaminated fluid. REFER to Power Transfer Unit (PTU) .
Note. Fill level checks are done in-vehicle only. Let the vehicle sit 10 minutes after the road test before checking the fluid level.

Scheme 46: General Procedure
- With the vehicle in NEUTRAL, position it on a hoist. REFER to «JACKING AND LIFTING»(ref-517532-S17733021342012121200000) for lifting points.
- NOTE: Clean the area around the fill plug before removing. Remove and discard the fill plug.
- With the vehicle on a flat, level surface, fill the PTU. The fluid must be even with the bottom of the fill opening. Fluid capacity is 0.53 L (0.56 qt).
- Install a new fill plug. Tighten to 20 Nm (177 lb-in).
