V. DETERMINE STATUS OF CURRENT ECU 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 software update to the
Advance Parking Guidance/ICS/Intuitive P/A System, as detailed
in these instructions. It does not cover the diagnosis or
replacement of any other systems on the vehicle.

2. CHECK CURRENT CALIBRATION
a. Locate the Update column for the ADVANCED PARKING GUIDANCE/ICS/INTUITIVE P/A
ECU in the Stored Data tab for this vehicle.
b. Determine the status of an available update; indicated by a YES or NO.

YES

Is there an update available for the

VI. VEHICLE PREPERATION
1. UNPLUG COOLING FAN
a. Disengage the claw and raise the lock lever to disconnect
the cooling fan motor connector. This will prevent the fans
from running during the re-flash procedure and reducing
the battery voltage.

Note: Prius shown. Other models are similar.

2. 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.
3. 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).

4. 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 also be maintained during
the re-flash procedure. If necessary, plug the Techstream into a
120v outlet during this procedure.
Note: If the Techstream communication with the vehicle fails during the re-flash procedure,
the Clearance Warning ECU will be damaged.

5. RECORD CUSTOMIZED SETTINGS
The customized setting for this ECU will be lost during the Calibration update. It will be necessary to
record the customers settings, prior to the update, to return the vehicle to its original condition.

a. Use a Techstream to access the following data:
• Advance Parking Guidance/ICS/Intuitive P/A → Customize → Warning, Sensor,
Display, and Others.
b. Record the Customized Settings on the sheets provided in Section: X APPENDIX on p. 9.

6. PRESSURIZE HYDRO-BOOSTER (Only for Hybrid vehicles)
a. Depress the brake pedal fully 2 times within 2 seconds.
b. Release the brake pedal.
c. Wait 10 seconds.
Note: You may hear the hydro-boost pump run for a few seconds when completing
these steps. The procedure will prevent the pump from running during the re-flash
procedure.

VII. UPDATE CALIBRATION
1. UPDATE THE ADVANCED PARKING GUIDANCE/ICS/INTUITIVE P/A ECU
a. Identify the vehicles Original CID for the Advanced Parking Guidance/ICS/Intuitive P/A ECU on
the Stored Data tab.

Original CID

b. Locate the vehicles Original CID in the chart on the following page.
c. Select the corresponding NEW CID link to load the update.
d. Follow the on-screen instructions to complete the ECU re-flash procedure.
The CID Update Procedure is detailed in T-SB-0134-16. Please reference this Bulletin for
more detailed procedures and information.
