Introduction
This bulletin details the procedure for loading configuration data (also known as As-built data) in
the ECUs of 2016 – 2020 model year Yaris Sedan Mexico-produced and 2017 – 2018 model year

be loaded into the ECU when replacing one of the ECUs listed below:
PCM (Engine ECU).

Load Configuration Data
Introduction (continued)
There are two different ways to load configuration data into a new ECU:
1. The data must be saved from the old ECU to load into the new ECU. This method is used
when an ECU requires replacement, however you can still communicate with the ECU and
read the existing As-built data. This is the preferred method and should be attempted first, as it
will ensure that the current ECU calibration is reinstalled on the ECU after repair
(for TCM and PCM).
Follow steps 1 – 8 of the Repair Procedure in this bulletin for instructions on how to save the
data. Once at step 8, start over at step 1 after replacing the ECU to load the data.
2. The data can be downloaded from the server. Downloading the calibration from the server will
load the original calibration as it was built from the factory (for TCM and PCM). This method is
used when you can no longer communicate with the ECU, or the Repair Manual has instructed
you to re-load As-Built Data without replacing the ECU.
Follow the Repair Procedure to load data from the server into the ECU.
