DTC Descriptor
DTC P0897
- Transmission Fluid Life



Circuit/System Description

Transmission fluid life is determined by monitoring transmission fluid temperature over a period of time. The transmission control module (TCM) calculates transmission fluid life based on a set of temperature ranges stored in TCM memory. As the vehicle is driven the TCM will begin to decrease the fluid life percentage from 100, high fluid life, to 0, low fluid life.

Conditions for Running the DTC

* DTCs P0711, P0712, or P0713 are not set.
* The ignition voltage is between 8 and 18 volts.


Conditions for Setting the DTC

The transmission fluid life is less than 10 percent.

Action Taken When the DTC Sets

DTC P0897 is a Type C DTC.

Conditions for Clearing the DTC

DTC P0897 is a Type C DTC.

Circuit/System Verification

Ignition ON, using a scan tool verify that the transmission oil life parameter is more than 10 percent.

Circuit/System Testing

Ignition ON, using a scan tool verify that the transmission oil life parameter is more than 10 percent.

If less than the specified range change the transmission fluid and filter.


Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the repair.

Use a scan tool to reset the transmission fluid life monitor. Refer to Control Module References (Programming and Relearning).
