EATX DTC Event Data

EATX DTC EVENT DATA can be used as a diagnostic aid when experiencing Electronic Transmissions with intermittent problems. When a Diagnostic Trouble Code (DTC) is set, the vehicles EATX inputs are stored in the controller memory and are retrievable with the DRBIII(R). This information can be helpful when a DTC can not be duplicated.

The EATX DTC EVENT DATA is located in the DRBIII(R), under the Transmission system menu, in the sub-screen Miscellaneous. It is a good practice to document the EATX DTC EVENT DATA before beginning any diagnostic or service procedure.

A thorough understanding of how the transmission works is beneficial in order to interpret the data correctly. These skills are necessary in order to avoid an incorrect diagnosis. A MASTERTECH video and reference book was produced in January 2002 that explains many of the features of the EATX DTC EVENT DATA with several examples on how to interpret the information and suggested training material to help understand all the specifics.

EATX DTC EVENT DATA can only be erased by:
1. Disconnecting the battery.
2. Performing a DRBIII(R) QUICK LEARN procedure.
3. Reprogramming the EATX controller.
Erasing Transmission DTC's does not clear the EATX DTC EVENT DATA.
