ECM REPLACEMENT PROCEDURES WITH CONSULT III PLUS
APPLIED VEHICLES:

All 2004 and later

IF YOU CONFIRM:
The Electronic Control Module (ECM) needs to be replaced on a 2004 MY and later vehicle.
ACTIONS:
After installing ECM:
•

Perform ECM Re-communicating Function (if supported).

•

Perform the “ACCELERATOR PEDAL & THROTTLE VALVE CLOSED POSITION LEARNING”
procedure (see step 3).

•

Perform the “IDLE AIR VOL LEARNING” procedure (when applicable) using CONSULT-III plus (CIII
plus). (See step 4)

•

For 2005 and later vehicles, enter the vehicle VIN into the new ECM (see step 5).

•

Check for any new updates for the new ECM you’re installing (see step 6).

CAUTION:
•

Failure to perform all the work steps in the specified order can cause poor engine running, MIL ‘ON’, or
vehicle emission test rejection.

•

Some vehicles may have Additional Services When Replacing the ECM not covered within this
bulletin. Refer to the model specific ESM and CIII plus “Maintenance” tab for any additional model
specific services.

IMPORTANT: The purpose of "ACTIONS" (above) is to give you a quick idea of the work you will be
performing. You MUST closely follow the entire Service Procedure (starting on page 3) 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 dealer to determine if this
applies to your vehicle.

SERVICE PROCEDURE
ECM Re-communication Function
1. Re-communicate the ECM with the BCM or Intelligent key.
•

Performing the following procedure can automatically perform a re-communication of a new ECM with
a BCM or Intelligent Key unit (not all models supported) so that the NATS keys do not need to be
registered.
o This Function will only work when the ECM has been replaced with a new one which has
never been energized onboard.
o If this function is not supported all of the keys may need to be individually registered.
a. Install new ECM.
b. Use a registered key (*) to turn ignition switch to “ON”.
* To perform this step, use a key that is registered to the original ECM that was replaced.
c. Maintain ignition switch in the “ON” position for at least 5 seconds.
d. Turn ignition switch to “OFF”.
e. Start engine.
¾ If engine can be started continue to step 3.

2. If engine will NOT start, after you perform the ECM Re-Communication Function, all ignition keys will need
to be individually registered, including spare keys with CIII plus and then proceed with step 3.

• Refer to the Immobilizer tab on the CIII plus home page to register keys.
NOTE:
•

When registering new Key IDs or replacing the ECM with other than brand new unit, refer to the
Immobilizer tab on the CIII plus home page.

•

If multiple keys are attached to the key holder, separate them before work.

•

Distinguish keys with unregistered key ID from those with registered ID.

Accelerator Pedal & Throttle Valve Closed Position Learning
3. Perform the Accelerator Pedal & Throttle Valve Closed Position Learning as follows:
a. Make sure the accelerator pedal is fully released.
b. Turn the ignition switch "ON" for 2 seconds.
c. Turn the ignition switch “OFF” for 10 seconds.
d. Turn the ignition switch "ON" for 2 seconds, then
e. Turn the ignition switch "OFF" again for 10 seconds (see Figure 1).

Perform Idle Air Volume Learning (IAVL)
NOTE: Make sure all electrical loads are turned OFF, including A/C, defroster, radio, lights,
etc. while performing the following procedures. Also, make sure the engine cooling fans are
NOT operating during the following procedures.
4. Perform the Idle Air Volume Learning procedure as follows:
a.

Connect CIII plus to the vehicle.

b.

Warm up engine and transmission to
operating temperature.

NOTE: Vehicle may have to be driven to warm
transmission enough to allow IAVL to complete.

c. In the CIII plus “Maintenance mode”, select
“IDLE AIR VOL LEARN” and then “Confirm”.
See Figure 2.

COMAND SUCCEDED
c. Once completed (COMAND SUCCEDED;
See Figure 8) turn the ignition off for 10
seconds, then back on and check for any
DTCs.
d. Select “READ VIN” and confirm that the VIN
is correct.
•

If VIN does not display it can also be
checked through the “RE/programming,
Configuration” tab.
Figure 8

Check for ECM Updates
6. Check and confirm that ECM is updated to most recent part number and perform reprogram procedure if
not most current.
¾ Select and use the reprogramming option that does not have the message “Caution! Use ONLY
with NTBXX-XXX”.
•

If you are not familiar with checking for an ECM update or with the reprogramming procedure
click here. This will link you to the C-III plus “ECM Reprogramming general procedure”.

•

If an update is not listed and a blank screen is displayed (see figure 9), a reprogram is not available for
the ECM.
