Please discard previous versions of this bulletin. APPLIED VEHICLES: 2015 – 2021 Q50 (V37) 2015 – 2018 Q50 Hybrid (HV37) 2017 – 2021 Q60 (CV37) 2015 – 2019 Q70 (Y51) 2015 – 2018 Q70 Hybrid (Y51) 2015 – 2017 QX50 (J50) 2019 – 2021 QX50 (J55) 2015 – 2020 QX60 (L50) 2015 – 2019 QX60 Hybrid (L50H) 2015 – 2017 QX70 (S51) 2015 – 2021 QX80 (Z62) IF YOU CONFIRM The Intelligent Key intermittently or continuously does not function. ACTION Check the battery condition with the Signal Tech-II “I-Key Battery Test.” IMPORTANT: Confirm that the Signal Tech-II has the most recent update. Updates can be performed through ASIST / Specialty Tools / Signal Tech-II. Up/down arrows OK button ON/OFF button Figure 1 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. 1/9 SERVICE PROCEDURE Intelligent Key Battery Condition Check 1. Turn ON the Signal Tech-II (see Figure 1 on page 1). NOTE: This procedure will refer to the yellow up/down arrows and OK button on the Signal Tech-II key pad. Refer to Figure 1 on page 1 as needed. Main Menu 2. Using the Signal Tech-II key pad, scroll to Toolkit with the yellow arrows and then press OK. TPMS Check Toolkit Active Sensor Other Brands Unknown Selection Settings Figure 2 Toolkit 3. Scroll to I-Key Battery Test, and then press OK. Car/Key Signals Test I-Key Battery Test Engine DTC Check Figure 3 4. Scroll to (highlight) the model you are working on, and then press OK. I-Key Battery Test Pathfinder QX60 JX35 Rogue Q50 Murano Figure 4 2/9 ITB15-026D QX60 (example) 5. Select (highlight) model year range, and then press OK. 2013-20 Figure 5 6. When Figure 6 is displayed, read the on-screen message and then press OK. NOTE: On-screen instructions will aid in completing the Intelligent Key battery test. 7. Press the Intelligent Key lock button 3 times: Figure 6 1st press – wait one second I-Key Battery Test 2nd press – wait one second 3rd press – wait one second A check mark will appear next to Read 1, 2, and 3 with each press of the lock button. Read 1 Read 2 Read 3 Press the lock button on the I-Key and please wait… Figure 7 NOTE: In some rare cases the Intelligent Key battery may be too weak to transmit or the Intelligent Key may no longer function; check marks will not appear next to Read 1, 2, or 3. In this case, go to Manual Battery Voltage Test on page 5. 3/9 ITB15-026D 8. When step 7 is complete, the message in Figure 8 or Figure 9 will display. I-Key Battery Test I-Key Battery Test Battery Weak, replace battery Press OK to Continue Battery OK Press OK to Continue Figure 8 Figure 9 9. If the message displayed is: Battery OK Press OK to Continue The battery is OK and does not need to be replaced. Refer to the Electronic Service Manual (ESM), section DLK – Door & Lock for further diagnosis. Battery Weak, replace battery Press OK to Continue Replace the Intelligent Key battery. Measure old battery’s voltage with a DVOM and write the voltage on the repair order. Perform steps 6 – 8 on pages 3 – 4 again. 4/9 ITB15-026D Manual Battery Voltage Test 10. Remove the mechanical key from the Intelligent Key. 11. Place a piece of tape on the end of a small flathead screwdriver. 12. Gently insert the screwdriver into one of the slots shown in Figure 10 and Figure 11. Slots for screwdriver Figure 10 Figure 11 NOTE: Figure 10 and Figure 11 show the proper location to insert a tool to open the Intelligent Key. DO NOT insert a tool into the notches on the side of the Intelligent Key (if equipped) to pry it open, as this may damage the printed circuit board. DO NOT use excessive force when opening the Intelligent Key, as this may result in damage to the internal components. Do not use excessive force (Example of damage to internal components shown.) Figure 12 5/9 ITB15-026D 13. Gently rotate the screwdriver until the two covers separate. Gently rotate screwdriver Top Top cover Bottom Bottom cover Figure 13 Figure 14 14. Remove the battery and check the voltage. Two methods can be used: Check voltage with resistor (load test) Check voltage without resistor Refer to the ESM for Intelligent Key battery diagnosis procedure. If a resistor is unavailable, use a volt/ohm meter (VOM) to check the battery voltage. If battery voltage is not within the 2.5 – 3.0 range, replace battery. NOTE: When inserting the new battery, make sure the + side of the battery faces the bottom cover piece. If the battery voltage is 2.7 or less, replace the battery. NOTE: When inserting the new battery, make sure the + side of the battery faces the bottom cover piece. If battery voltage is within the 2.5 – 3.0 range, refer to the ESM for further diagnostic information. If the battery voltage is more than 2.7, refer to the ESM for further diagnostic information. 15. Reattach the two cover pieces by pushing them together. 16. Confirm all Intelligent Key functions operate correctly. 6/9 ITB15-026D Intelligent Key Frequency Check The frequency of the Intelligent Key signal may be 315 MHz or 433/434 MHz. For diagnostic purposes, sometimes TECH LINE or other Nissan technical staff will ask for the frequency (315 MHz or 433/434 MHz) of an Intelligent Key you are working on. The following steps can be used to check the signal frequency. 1. Turn ON the Signal Tech-II. Main Menu 2. Using the Signal Tech-II key pad, scroll to Toolkit with the yellow arrows and then press OK. TPMS Check Toolkit Active Sensor Other Brands Unknown Selection Settings Figure 15 Toolkit 3. Scroll to Car/Key Signals Test, and then press OK. Car/Key Signals Test I-Key Battery Test Engine DTC Check Figure 16 7/9 ITB15-026D 4. Hold the Intelligent key near the Signal Tech-II and press the Lock or Unlock button. 5. The signal strength and frequency (315 MHz or 433/434 MHz) will be displayed.
