APPLIED VEHICLES: 2013 JX35 (L50) equipped with Intelligent Cruise Control 2014 QX60 (L50) equipped with Intelligent Cruise Control 2014-2015 Q50 (V37) equipped with Intelligent Cruise Control NOTE: Does not apply to Hybrid models APPLIED DATE: 2013 JX35 – All 2014 QX60 – AWD models built before May 6, 2014 FWD models built before August 11, 2014 2014 Q50 – All 2015 Q50 – AWD models built before December 26, 2014 FWD models built before December 25, 2014 IF YOU CONFIRM All of the following: The FCW (Forward Collision Warning) malfunction is ON or reported to have been ON, and DTC C1A27 (ECD POWER SUPPLY CIRCUIT) is stored (Past or Current), and The brake fluid level is normal. NOTE: C1A27 is an ICC (Intelligent Cruise Control) DTC. FCW Malfunction See Owner’s Manual Figure A: JX35/QX60 combination meter Figure B: Q50 combination meter IMPORTANT: The purpose of ACTION (on the next page) is to give you a quick idea of the work you will be performing. You MUST closely follow the entire SERVICE PROCEDURE as it contains information that is essential to successfully completing this repair. Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti retailer to determine if this applies to your vehicle. 1/15 ACTION Reprogram the ABS control unit (ABS) per the Service Procedure in this bulletin. Part of the Service Procedure, step 20 on page 8, is a confirmation that reprogramming is needed to resolve the incident shown in Figure A and B on page 1. SERVICE PROCEDURE IMPORTANT: Before starting, make sure: ASIST on the CONSULT PC has been synchronized to the current date. All CONSULT-III plus (C-III plus) software updates (if any) have been installed. NOTE: The CONSULT PC automatically gets applicable reprogramming data during ASIST synchronization. A screen print for Warranty documentation can be done from the CONSULT PC during this process while still connected to the vehicle. No DTCs stored. Use C-III plus to perform Self Diagnosis for all systems. If there are any DTCs other then C1A27, diagnose, perform repairs, and erase DTCs before continuing. If only DTC C1A27 is stored, erase DTC before continuing. 1. Connect the plus VI to the vehicle. CAUTION: Make sure the plus VI is securly connected. If the plus VI connection is loose during reprogramming, the process will be interrupted and the the control unit may be damaged. 2. Connect the AC Adapter to the CONSULT PC. CAUTION: Be sure to connect the AC Adapter. If the CONSULT PC battery voltage drops during reprogramming, the process will be interrupted and the control unit may be damaged. 2/15 ITB14-051a 3. Connect the GR8 and set to “Power Supply” mode. CAUTION: Be sure the battery charger is connected securely to the battery. Make sure the battery voltage stays between 12.0V and 15.5V during reprogramming. If the battery voltage goes out of this range during reprogramming, the control unit may be damaged. 4. Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range of the CONSULT PC and the VI. CAUTION: Make sure to turn off all external Bluetooth® devices. If Bluetooth® signal waves are within range of the CONSULT PC and the VI during reprogramming, reprogramming may be interrupted, and the control unit may be damaged. 5. Turn the ignition ON with the engine OFF. The engine must not start or run during the reprogramming procedure. 6. Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC, blower, rear defogger, audio, NAVI, seat heater, steering wheel heater, etc. IMPORTANT: Make sure to turn OFF all vehicle electrical loads. Make sure the battery voltage stays between 12.0V and 15.5V during reprogramming. If the battery voltage goes out of this range during reprogramming the control unit may be damaged. 7. Turn ON the CONSULT PC. 8. Select CONSULT-III plus (open C-III plus). 3/15 ITB14-051a 9. Wait for the plus VI to be recognized. Serial number will display when the plus VI is recognized. Step 9: plus VI is recognized Figure 1 10. Select Re/programming, Configuration. Step 10 Figure 2 4/15 ITB14-051a 11. Use arrows (if needed) to view and read all precautions. 12. Check the box confirming the precautions have been read. 13. Select Next. Step 11 Step 12 Step 13 Figure 3 14. If the screen in Figure 4 displays, select Automatic Selection(VIN). If the screen in Figure 4 does not display, skip to step 15. Step 14 Example Figure 4 5/15 ITB14-051a 15. Verify the VIN or Chassis # matches that of the vehicle. 16. If the correct VIN is displayed, select Confirm. Step 15: Verify here Step 16: If OK, select Confirm Figure 5 17. Select Confirm again. Step 17 Figure 6 6/15 ITB14-051a 18. Select ABS. Use the scroll arrows as needed. Step 18 Scroll arrows Figure 7 19. Wait for System Call to complete and then select Reprogramming. Step 19 Figure 8 7/15 ITB14-051a 20. When you get to the screen shown in Figure 9, confirm reprogramming applies as follows: a. Find the ABS Part Number and write it on the repair order. NOTE: This is the current ABS Control Unit Part Number. 20a: Current Part Number 20c: If OK, select Save Figure 9 b. Compare the P/N you wrote down to the numbers in the Current Part Number column of Table A below: If there is a match, this bulletin applies. Continue with the reprogramming procedure on the next page. If there is not a match, this bulletin does not apply. Close C-III plus and check ASIST for further diagnostic and repair information. c. If there is a part number match as specified below, select Save and then continue with the reprogramming procedure on the next page.
