TSB's

Infiniti tick

This TSB applies to a 2008 Infiniti G37 coupe that experiences a slight ticking/tapping/knocking noise coming from the bank 2 (driver side) VVEL (variable valve event and lift actuator).

Refer to Step 2 to confirm that this bulletin applies to the vehicle that you are working on. If this bulletin applies, reprogram the ECU.

 Connect C-III to the vehicle to begin the reprogramming procedure.

  1. When you get to the ECM Reprogramming screen shown in Figure 1, confirm that this bulletin applies as follows:
    1. On your C-III screen, look at the Part Number column. If this column is blank, this bulletin does not apply. Close C-III and refer to ASIST for further diagnostic information. If a part number is listed, write it on the repair order.
    2. Compare the part number you wrote down to the numbers in the Current ECM Part Number column in Table A. If there is a match, this bulletin applies. Continue with the reprogramming procedure. Note: If there are two lines (two reprogramming options) on your C-III screen, use the one that does not have the message “Caution! Use ONLY with ITBXX-XXX.” If there is not a match, this bulletin does not apply. Close C-III and refer to ASIST.

  1. If this bulletin applies and you have performed ECM reprogramming, the screen in Figure 2 displays when the reprogramming is complete.
  2. Erase all DTCs from all systems.
  3. Test drive the vehicle to verify proper operation that that the check engine light is off. If the MIL illuminates, diagnose, perform repairs and erase DTCs.
