IV. BACKGROUND
The engine ECUs in the subject vehicles are equipped with software to monitor the rear oxygen sensors. Under a
specific condition, this software may not detect a malfunctioning sensor due to an error in the software. As a result,
affected vehicles do not meet certain onboard diagnostic (OBD) regulations.

V. DETERMINE STATUS OF CURRENT CALIBRATION
1. CHECK FOR DTC’S
a. Using a Techstream, perform a Health Check to check for
any Diagnostic Trouble Codes.
Note: This Campaign covers only the Calibration ID update to
the Engine and ECT system, as detailed in these instructions. It
does not cover the diagnosis or replacement of any other
systems on the vehicle.

2. CONFIRM THE ECM CALIBRATION ID
a) Perform a Health Check.
b) Confirm the current calibration ID in the ECM (and transmission ECU).
c) Referencing the table below, verify if the ECM (and transmission ECU) has the updated
Calibration(s).
NOTE:
• The current calibration ID of either is shown depending on the vehicle model and specifications.
• In SIENNA, it is necessary to check the 2 IDs of the engine ECU and the transmission ECU.

VI. VEHICLE PREPERATION
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 (GR8)
a. Connect the GR8 or other type of a power supply (not a battery charger) to the 12v battery.
b. Select the Power Supply Mode from the Charge Menu of the GR8.
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).

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’s battery voltage must be maintained during the
update procedure. If necessary, plug the Techstream into a 120v
outlet during this procedure.
Note: If the Techstream’s communication with the vehicle fails during the update
procedure, the Engine ECU will be damaged.
The CID Update Procedure is detailed in T-SB-0134-16. Please reference this Bulletin for more

UPDATE CALIBRATION
Always confirm the both CID of the engine and the transmission in SIENNA, and judge
whether reflash is necessary or not.
If either the engine or transmission CID does not match the NEW CID, ECU reflash is
necessary.
If the ECM has already been calibrated with the new calibration the campaign is complete.
