REVISION NOTICE
December 17, 2019 Rev1:
 The Parts and Calibration tables have been updated.
Any previous printed versions of this bulletin should be discarded.
Introduction
Some 2019 model year RAV4 vehicles may exhibit a hesitation on acceleration from a slow roll or
rolling stop under all of the following conditions.

6 mph or below

Immediately following a 3 – 1 downshift

Less than 40% accelerator pedal application
The Engine Control Module/ECM (SAE Term: Powertrain Control Module/PCM) logic has been
modified to reduce the potential for hesitation. Follow the Repair Procedure in this bulletin to
update the ECM calibration.
NOTE
This Service Bulletin requires a drive pattern to be performed after the calibration update is completed.
The proper execution of these drive patterns is necessary for the drivability updates to take effect.
Refer to the Repair Procedure for drive pattern details.

Repair Procedure (continued)
NOTE
 This Service Bulletin requires a drive pattern to be performed AFTER the calibration update is
completed. The proper execution of these drive patterns is necessary for the modification to take
effect as soon as possible. Step 5 describes the drive pattern details.
 When performing step 5, you MUST take the vehicle to a safe, open area or low traffic location
to perform the drive pattern.
 Use care when viewing Techstream and performing the drive patterns. Consider using another
technician for Techstream confirmation of Shift Status.
5. Drive the vehicle to a safe and appropriate location where the following drive patterns can be
performed. Then, perform the following drive patterns.
A. From a speed of 18 – 22 mph, apply consistent braking to decelerate to 0 mph in
3 seconds. Complete this pattern 15 times.
(1) Using Techstream, monitor the transmission shift status and ensure that the vehicle
shifts from 3rd – 1st gear (skip 2nd gear) during each deceleration attempt.
B. From a speed of 18 – 22 mph, apply consistent braking to decelerate to 0 mph in
15 seconds. Complete this pattern 15 times.
(1) Using Techstream, monitor the transmission shift status and ensure that the vehicle
shifts from 3rd to 2nd to 1st gear during each deceleration attempt.
6. Return the vehicle to the customer and explain that the transmission shift schedule has been
modified and should adapt to the customer’s driving habits as the vehicle is driven.
