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 SYMPTOM CHART: POWER TRANSFER UNIT (PTU) .
