This TSB outlines all steps necessary to prevent reprogramming failure. Lexus will not provide reimbursement coverage for reprogramming failures if this TSB is not followed. If you have a reprogramming failure that requires skid control ECU replacement and the Technical Instructions and TSB were followed correctly, please create a case with the Technical Assistance Hotline documenting all information related to the failure. If sufficient reporting is received related to re-flash failure, there will be consideration for reimbursement. Is there an update available for the Brake/EPB System? Campaign complete. Return the vehicle to the customer. Proceed to section VII. Vehicle preparation on p.4 Yes No 4 VII. 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. (w/ DRL OFF position) • Windshield wiper switch in the OFF position. b) When the vehicle has no “OFF position” in the light control switch: 1) Turn the IG ON. 2) Set the light control switch to the AUTO position and make sure that the exterior lights are turned on. 3) Light up the automatic light control sensor with work light to keep the exterior lights turned off. 2. CONNECT THE 12V BATTERY TO A POWER SUPPLY a) Connect the DCA-8000 or other type of a power supply (not a battery charger) to the 12 V battery. b) Tap 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. 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 120 V 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 120 v outlet during this procedure. NOTICE: If the Techstream communication with the vehicle fails during the re-flash procedure, the skid control ECU will be damaged. 5 VIII. UPDATE CALIBRATION 1. CONFIRM THE ECU CALIBRATION ID a) Confirm the current calibration ID in the Brake/EPB System. The calibration IDs to re-flash in this campaign are as shown in the table below. Brake/EPB Calibrations Model System Brake/EPB Calibration ID Current Calibration ID New Calibration ID NX Brake/EPB F15267835400 F15267835500 2. REFLASH THE SKID CONTROL ECU a) Click yes on the health check results screen, or follow the link on the table above to begin the reflash process.

The brake actuator may produce a loud operating sound when the engine starts for the first time after reprogramming. b) The zero point calibration is complete when the brake actuator falls silent. HINT: The skid control ECU stores the amount of the fluid inside the brake actuator in its memory, and such information will be reset when the ECU is reprogrammed. If the memory is reset, the system rapidly drains the fluid out of the brake actuator when the engine starts, and this may cause the brake actuator to emit a loud operating sound. The zero point calibration is complete once the residual fluid is drained out, and the operating sound returns to normal. 7 5. PRINT CUSTOMER HEALTH CHECK REPORT a) From the Stored Data tab, select the Customer Health Check Report button (TIS will launch when button is pressed). b) Log in to TIS. c) Input Vehicle Mileage and Repair Order number. d) Check the “Performed” campaign button for campaign 22LA04. e) Select the Report button. f) Confirm Customer Health Check Report information is correct. g) Print Customer Health Check Report from TIS. h) Sign and provide to the customer. 8 ◄ VERIFY REPAIR QUALITY ► – Confirm the system Calibration has been updated successfully. – Confirm there are no DTC’s after the Calibration update. – If you have any questions regarding this update, please contact your area representative.
