DETERMINE CID STATUS 1. DETERMINE STATUS of HYBRID CONTROL SYSTEM CIDs a. Locate the Update column for the Hybrid Control System in the Stored Data tab. b. Determine the status of CID’s #1 for the Hybrid Control ECU; indicated by a YES or NO in the Update column. CID’s #1 Status of available Update Diagram shown is from a Prius. Prius V will be similar. Does CID #1 of the Hybrid Control System indicate there is a UPDATE available? Proceed to Section VIII. Vehicle Preparation on p. 8 Proceed to Section XI. Complete Repair on p.15 YES No VIII. VEHICLE PREPARATION The ECU reprograming procedure is detailed in T-SB-0134-16. Reference this Bulletin for additional detailed procedures and information. 1. VEHICLE BASICS 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. Headlights, wipers, climate control, audio system, etc.) 2. CONNECT THE 12v BATTERY TO A POWER SUPPLY (GR8) a. Connect the DCA-800, 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: • Current version of software is installed (reference TIS for latest software version). • 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 communication with the vehicle fails during the re-flash procedure, the ECU will be damaged and must be replaced. 4. MAINTAIN BRAKE SYSTEM PRESSURE a. Depress the brake pedal fully 2 times within 2 seconds. Note: You may hear the hydro-boost pump run for a few seconds when completing these steps. This procedure will prevent the pump from running during the calibration update procedure. 9 5. REMOVE JOINT FUSE FROM ENGINE ROOM FUSE BOX a. Confirm the joint fuse orientation before removal because the fuse can be installed in either direction. b. Using the fuse puller remove the joint fuse that encases the CDS (30A), RDI (30A) and HTR (50A). Permanent damage to the ECUs can happen if these fuses are not removed. Removing these fuses will stop the vehicle from performing onboard diagnostic tests during the update, which could cause the update to fail and damage the ECU. IX. CUWC APPLICATION 1. INSTALL CUWC FILE INSTALLER (Only required once for each Techstream) a. In TIS, select the following: • TIS / Diagnostics / Reprogramming b. On the right side of the screen, select the following from the Reference Documents: • CUWC Reprogramming Installer • Follow the on-screen instructions to complete the installation. Note: The installation of the CUWC Reprogramming Installer will only need to be completed one time for each Techstream. (cont. on next page) 11 Permanent damage to the ECUs will occur if the following actions are attempted during the CID update procedure: • Attempt to close the CUWC installer • Attempt to close the Calibration Wizard • Turning off the vehicle’s ignition • Turning off the Techstream • Unplugging the Techstream from the vehicle while programming is in process The following message will appear when the CUWC installation application is running. This image cannot be closed manually. When the installation of all necessary CIDs is complete, the image will close. Message displayed during CID update process: (cont. on next page) X.
