ADDITIONAL INFORMATION
Introduction
When completing a transaxle assembly replacement, Engine Control Module (ECM) (SAE term:
Powertrain Control Module [PCM]) replacement, or ECM (PCM) reprogram, ensure the correct
ECM (PCM) software is matched with the transaxle assembly hardware. Some 2017 – 2018
model year Highlander and 2017 model year Sienna vehicles require different ECM (PCM)
software based on the transaxle assembly hardware installed in the vehicle.
NOTICE
Mismatched transaxle assembly hardware and ECM (PCM) software combinations may result
in a harsh shift or shift flare. If this occurs, ECM (PCM) replacement and reprogramming will be
required. If ECM (PCM) replacement/reprogramming is needed, it will not be covered
under warranty.
Use the information in this Service Bulletin to confirm that the correct ECM (PCM) hardware and
software are used based on the transaxle assembly part number and serial number.

 For transaxle replacement: Claim should be submitted as a normal replacement of the transaxle. If the
ECM (PCM) software needs to be updated when replacing the transaxle, add 0.3 hours of “Z time” to
the transaxle replacement OP code.
 For ECM (PCM) reprogramming or replacement: This Service Bulletin is used for ECM (PCM) and
software selection; however, this does NOT incur additional warranty cost.

Production Change Confirmation Procedure
For transaxle assembly replacement, use Option 1 below to confirm the transaxle assembly part
number and determine the appropriate ECM (PCM) software.
For ECM (PCM) replacement or reprogramming, go to Option 2 to determine the appropriate
ECM (PCM) software by transaxle assembly serial number if the transaxle assembly part number
cannot be determined.
Option 1: Confirmation by Part Number
1. Determine if the vehicle has a transaxle assembly produced BEFORE or AFTER the
production change using the table below.
Table 1.

2. Using the judgement from Table 1, refer to the Engine Control Computer (ECM/PCM)
Replacement Information and Calibration Information sections.
NOTE
If unable to determine the part number, continue to Option 2: Confirmation by Production Change

3. Flash reprogram the ECM (PCM).
NOTE
 The GR8 Battery Diagnostic Station MUST be used in Power Supply Mode to maintain battery
voltage at 13.5V while flash reprogramming the vehicle.
 For details on how to use the GR8 Battery Diagnostic Station, refer to the
GR8 Instruction Manual located at TIS – Diagnostics – Tools & Equipment – Battery Diagnostics.
Follow the procedures outlined in Service Bulletin No. T-SB-0134-16 “Techstream ECU Flash
Reprogramming Procedure,” and flash the ECM (PCM) with the NEW calibration file update.
