All dealership technicians performing this special service campaign are required to successfully complete the most current version of the E-Learning course “Safety Recall and Service Campaign Essentials”. To ensure that all vehicles have the repair performed correctly; technicians performing this special service campaign repair are required to currently have completed all of the following courses: – L623 Lexus Electrical Circuit Diagnosis It is the dealership’s responsibility to select technicians that have completed the above courses to perform this repair. Carefully review your resources, the technician skill level, and ability before assigning technicians to this repair. It is important to consider technician days off and vacation schedules to ensure there are properly trained technicians available to perform this repair at all times. 2 I. OPERATION FLOW CHART II. IDENTIFICATION OF AFFECTED VEHICLES • Check the TIS Vehicle Inquiry System to confirm the VIN is involved in this Campaign, and that it has not already been completed prior to dealer shipment or by another dealer. • TMS warranty will not reimburse dealers for repairs completed on vehicles that are not affected or were completed by another dealer. III. PREPARATION A. TOOLS, SUPPLIES & EQUIPMENT • Standard Hand Tools • Techstream ADVi / Techstream 2.0 / Techstream Lite • DCA-8000P Battery Diagnostic Tool • L-SB-0001-18 No Covered Yes Perform Health Check. Is a Update available for the Brake/EPB System? Update the Skid Control ECU CID’s. Not Covered Verify Vehicle Eligibility 1.Confirm vehicle VIN matches the RO. 2.Check Vehicle Inquiry System for Campaign eligibility. No further action required. Campaign completed, return the vehicle to the customer. Perform Verification Heath Check 3 IV. BACKGROUND A software error can cause the Vehicle Stability Control system (VSC) not to default to “ON” the next time the car is started under certain circumstances. This can result in noncompliance with a federal safety requirement. Operating the vehicle with VSC deactivated could increase the risk of a crash in certain driving conditions. 4 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. NOTICE: This Campaign covers only the Calibration ID update to the Brake/EPB system, as detailed in these instructions. It does not cover the diagnosis or replacement of any other issues on the vehicle. For LS w/ advanced drive, make sure to use a VIM which supports Ethernet communication. NOTICE: Before completing Health Check, “Send Vehicle Information” window may be displayed. If displayed, then click “Yes” to send the vehicle information. • If “Failed to send data to the server” is displayed, click “No” to close the window and proceed to the next step. 5 2. CHECK CURRENT CALIBRATION a. Locate the Update column for the Brake/EPB System in the Stored Data tab for this vehicle. b. Determine the status of an available update for the Brake/EPB System; indicated by a YES or NO. Is there an update available to the Brake/EPB System? No update is necessary. Campaign is complete. Proceed to section VI. Vehicle preparation on p. 6 Yes No 6 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. DISCONNECT COOLING FAN a. Disconnect the electrical connector 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). NOTICE: The illustration is an example of NX. 3. PRESSURIZE HYDRO-BOOSTER a. Depress the brake pedal fully 2 times within 2 seconds b. Release brake pedal c. Wait 10 seconds NOTICE: 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. 4. 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. Tap the Reflash icon from the Main Menu screen of the DCA-8000. A power supply MUST be used during reprogramming. Please ensure DCA-8000 is connected and set to power supply mode. Voltage MUST be set to 13.5V. Power supply must be connected directly to the 12v battery terminals and NOT the remote jump posts under the hood (if equipped). ***ECU damage will occur if the battery voltage is not properly maintained during this re-flash procedure. 7 5. 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. ***If the Techstream’s communication with the vehicle fails during the update procedure, the ECU will be damaged. b. This vehicle has additional security measures requiring a signature from the server when performing ECU reprogramming. 8 VII. UPDATE CALIBRATION 1. UPDATE THE CID’S FOR THE Brake/EPB SYSTEM a. Identify the vehicles Original CID for the Brake/EPB System on the Stored Data tab. b. Locate the vehicles Original CID in the chart below. c. Select the corresponding NEW CID link to load the update. Model Current Calibration ID NEW Calibration ID LS 500h F15265087100 F152650L6000 F15265087200 F15265087300 F15265087400 LX 600 F15266063100 F15266063200 NX 350h F15267832500 F15267832600 NX 450h+ F15267832500 F15267832600 NOTICE: • While reprogramming, keep IG ON. Never turn the IG off or ENGINE-START. • As reprogramming completes within approximately 30 minutes, stay near the vehicle and DO NOT allow any third parties to operate the vehicle or TS in order to prevent issues from occurring. • Never turn the IG off other than instructed. Otherwise, the ECU could be damaged. • Pressing the “Cancel” button or the “X” button on the top right means to cancel reprogramming and could damage the ECU while reprogramming.
