DTC Descriptor
DTC P0A2F
- Drive Motor 1 Overtemperature
Circuit/System Description
The transmission contains two electric motor generators. The drive motor generators are cooled by the transmission fluid. Hot fluid exits the drive
motor generator housing and flows to the transmission cooler supply line. The supply line connects to the cooler. From the cooler, the fluid returns
through the oil cooler return line and enters the lubrication circuits. After lubricating the internal components, the fluid returns to the oil pan. A
non-serviceable motor temperature sensor (MTS) is located in each drive motor generator assembly.
Conditions for Running the DTC
DTC P0A2B is not set.
Conditions for Setting the DTC
The MTS is greater than 200掳C (392掳F) for 3 seconds and has not fallen below 135掳C (275掳F).
Action Taken When the DTC Sets
* DTC P0A2F is a Type B DTC.
* The hybrid powertrain control module (HPCM) commands the battery energy control module (BECM) to open the high voltage contactor
relays.
Conditions for Clearing the DTC
DTC P0A2F is a Type B DTC.
Diagnostic Aids
* The driver information center (DIC), if equipped, will display 'TRANSMISSION HOT- Idle Engine' when the transmission fluid temperature
(TFT) is more than 132掳C (270掳F) for 10 minutes.
* Ask about the customer's driving habits, trailer towing, etc.
* Ensure the engine cooling system is functioning normally.
* The HPCM will reduce drive motor generator torque at temperatures greater than 160掳C (320掳F). Drive motor generator torque is reduced to
zero if the temperature reaches 190掳C (374掳F).
