BACKGROUND
In the involved vehicles, a software error can cause a control computer (hybrid vehicle ECU) to erroneously determine that it does not have the correct information about the transmission position if the position changes during a short window of time when the computer is checking this information. If this occurs, warning lights will illuminate and the hybrid system will shut down resulting in loss of motive power while driving. If the vehicle loses motive power while being driven at a higher speed, there could be an increased risk of a crash.

Reprogramming
Approved J2534 Devices only provide reprogramming capabilities and do not support diagnostic scantool functions. For full diagnostic capabilities, please consider TIS Techstream or Techstream Lite
Toyota, Scion, and Lexus ECMs can be reprogrammed with the TIS Techstream, Techstream Lite, Diagnostic Tester, or can also be reprogrammed using a Toyota validated J2534 interface. Vehicle recalibration requires the use of the following:
- TIS Professional Level Subscription
- Toyota Calibration Update Wizard software (installed along with Techstream Software)
- Personal Computer running Microsoft Windows XP/2000 or later operating system
Toyota strongly recommends USING ONLY VALIDATED INTERFACE DEVICES that appear on this list.

If this occurs, warning lights will illuminate and the hybrid system will shut down resulting in loss of motive power while driving. If the vehicle loses motive power while being driven at a higher speed, there could be an increased risk of a crash. 4 V. DETERMINE CALIBRATION UPDATE STATUS 1. PERFORM HEALTH CHECK a. Using a Techstream, perform a Health Check to check for any Diagnostic Trouble Code. Note: This Campaign covers only the Calibration ID update to the Hybrid Control systems, as detailed in these instructions. It does not cover the diagnosis or replacement of any other issues on the vehicle. 2. CHECK CURRENT CALIBRATION a. Locate the Update column for the Hybrid Control System’s in the Stored Data tab for this vehicle. b. Determine the status of an available update for the Hybrid Control Systems; indicated by a YES or NO 5 Note: If the Hybrid System’s ECU already has the updated Calibration ID, the campaign is complete. No further action is required. Submit the warranty claim to complete this vehicle. VI. VEHICLE PREPERATION The ECU reprograming procedure is detailed in T-SB-0134-16. Reference this Bulletin for additional detailed procedures and information. 1. VEHICLE PREPARATION a. Confirm the following conditions: • Vehicle in the IG position (engine off). • Transaxle in Park. • Parking brake engaged. • Turn off all electrical accessories (i.e. climate control, audio system, etc.) • Headlight switch in the DRL OFF position. • Windshield wiper switch in the OFF position. 2. CONNECT THE 12v BATTERY TO A POWER SUPPLY (DCA-8000) a. Connect the DCA-8000 or other type of a power supply (not a battery charger) to the 12v battery. b. Select the Reflash icon from the Main Menu screen of the DCA-8000. A power supply MUST be used during reprogramming. ECU damage will occur if the battery voltage is not properly maintained during this re-flash procedure. Note: A power supply must be connected directly to the 12v battery terminals and NOT the remote jump posts under the hood (if equipped). Is there an update available to the Hybrid Control System? No update is necessary. Campaign is complete. Proceed to section VI. Vehicle preparation on p. 4 Yes No 6 3. VERIFY TECHSTREAM SETUP a. Verify that the Techstream meets the following conditions: • The latest version of software is loaded. • The Techstream battery is fully charged. If not, connect the Techstream to a 120v source. • The DLCIII cable is in good condition. The Techstream battery must be maintained during the update procedure. If necessary, plug the Techstream into a 120v outlet to ensure that a failure does not occur. Note: If the Techstream’s communication with the vehicle fails during the update procedure, the ECU will be damaged. The CID Update Procedure is detailed in T-SB-0134-16. Please reference this Bulletin for more detailed procedures and information. 1. DISCONNECT COOLING FAN a. Disconnect the 2 electrical connectors from the cooling fan on the radiator fan shroud. If the cooling fans run during the Calibration update procedure, the battery voltage will be inconsistent and could cause damage to the control module(s). 7 VII. UPDATE CALIBRATION ID 1.
