Dakota 2WD V8-4.7L Flex Fuel (2009)
The PCM continually monitors the transmission temperature sensor to determine the transmission operating condition. The PCM then sends the proper
lamp-on or lamp-off message to the instrument cluster, also known as the Cab Compartment Node (CCN). If the instrument cluster illuminates the
transmission over temperature indicator due to a high transmission oil temperature condition, it may indicate that the transmission or the transmission
cooling system are being overloaded, or that they require service. For further diagnosis of the transmission over-temperature indicator or the instrument
cluster circuitry that controls the LED, See: Instrument Panel, Gauges and Warning Indicators/Instrument Cluster / Carrier/Testing and
Inspection/Component Tests and General Diagnostics.
Use a diagnostic scan tool for proper diagnosis of the transmission temperature sensor, the PCM, the CCN, the CAN data bus or the electronic
communication related to transmission over-temperature indicator operation. Refer to the appropriate diagnostic information.
