Heat Protection Mode

The AWD  system utilizes a heat protection mode to protect the PTU  and the ATC  solenoid from damage due to heat build up caused by clutch slippage while driving in extremely slippery road conditions. If the AWD  system detects an overheat condition, it increases the duty cycle to keep the clutches from slipping. If the heat in the system continues to rise, the AWD  relay module disables the ATC  solenoid. This condition may be indicated by an AWD  OFF message in the message center. Allow the system to cool down at least 10 minutes with the ignition ON (RUN). For concerns with the PTU  , REFER to TRANSFER CASE - POWER TRANSFER UNIT (PTU) - SYMPTOM CHART: PTU .
