Section 1 - 6

The sections must be performed in order 1 through 6.

Section 1: Connect ICC reprogramming cable to the ICC control unit.

Section 2: Connect a battery charger and CONSULT-II to the vehicle.

Section 3: Check / adjust the vehicle battery voltage / CONSULT-II "Charger Input voltage.

Section 4: Check CONSULT-II Converter version.

Section 5: Perform ICC Control Unit Reprogramming.

Section 6: Perform "erase" procedure for all systems in SELF-DIAG RESULTS.

Section 1: Connect ICC reprogramming cable to the vehicle.

1. Remove the front grille.

a. Open the hood.





b. Remove the 4 upper clips shown in Figure 11.

c. Release the clips "A" shown in Figure 11.

^ Pull the top of the grille forward and locate the clips on the back side. Using pliers squeeze the top and bottom of each clip to release them.





d. Hold the grille with both hands as shown in Figure 11a.

e. Pull the grille straight forward to release it from the bottom clips.

NOTE:
^ The lower clips are firmly attached. A "Sharp pull" may be needed to remove them.

^ If needed a small screwdriver can be used to disengage the lower clips from behind the grille.





2. Reach behind the bumper and disconnect the ICC control unit connector.





3. Connect the ICC reprogramming cable as shown in Figure 13.

4. Continue with section 2.

Section 2: Connect a battery charger and CONSULT-II to the vehicle.

1. Make sure the ignition switch is OFF.

2. Connect a battery charger to the vehicle battery.

WARNING:
Battery charging will produce flammable gas.

^ Remove cell caps from the battery (if applicable).

^ Make sure the area around the battery and vehicle is well ventilated.

3. Set the charger at a low charge rate (trickle charge).

IMPORTANT CAUTION
You must connect a battery changer to the vehicle battery when performing ICC reprogramming. Permanent ICC damage can occur if you don't. Connecting a vehicle battery charger will maintain:

^ Proper CONSULT-II power supply during reprogramming-very important if the CONSULT-II battery is low.

^ Vehicle battery voltage level during the approximate 25 minute reprogramming time.





4. Connect CONSULT-II to the ICC reprogramming cable using the DLC-II cable with black Converter Box (see Figure 14).

VERY IMPORTANT:
^ Make sure the ICC reprogramming cable is tightly connected to the vehicle harness and the ICC control unit (Refer back to Figure 13).

^ Make sure the DLC-II is pushed in straight and fully plugged in to the ICC reprogramming cable.





^ Make sure all other DLC-II cable connections (as shown in Figure 15) are connected properly.

CAUTION
^ Infiniti requires the use of essential tools shown in Figure 15 when performing ICC reprogramming.

^ J44200-10 Pigtail should not be removed from the CONSULT-II DDL Port. This Pigtail allows use of the stronger quick disconnect cable set.

^ If cables are very often changed at the DDL Port (base) of the CONSULT-II unit cable connector pin damage may result.

^ If there is connector pin damage ICC reprogramming may fail. Permanent damage to the ICC system can occur.

5. Turn the ignition ON.

^ Do Not start the engine.

^ CONSULT-II will turn ON automatically.

^ Confirm that all electrical loads* (except for the ignition) are QLF.

^ * These loads include headlights defroster A/C audio (radio) video cellular telephone etc.





6. Make sure the CONSULT-II Converter power LED is ON.





7. Roll down the driver's window part way exit the vehicle close the door and hang the CONSULT-II unit on the outside of the window.

8. Continue with Section 3.

Section 3: Check / adjust the vehicle's battery voltage / CONSULT-II "Charger Input" voltage





1. Press [SUB MODE] then select [BATTERY CHARGE].

CAUTION:
^ DO NOT connect the CONSULT-II AC power supply for Steps 2, and 3 in this section.





2. Check the CONSULT-II's Charger Input reading (see Figure 19).

NOTE:
^ "Battery Voltage" is the voltage level of CONSULT-II's battery.

^ "Charger Input" is the voltage level of the vehicle's battery. (It MUST be between 12 and 13.5 V.)

3. * Adjust the battery charger voltage (charge rate) so the Charger Input is between 12 V and 13.5 V.

^ Make sure the battery charger is adjusted so it will continue to charge for the entire reprogramming time; approximately 30 minutes.*

4. As mentioned the Charger Input reading MUST be above 12 volts (see Figure 19 previously shown).

^ A reading above 12 volts confirms;

a. The DLC-II is properly connected to the vehicle,

b. The vehicle battery voltage is sufficient for ICC reprogramming,

c. CONSULT-II has a sufficient power supply to perform ICC reprogramming.

^ If the vehicles battery voltage ("Charger Input" is below 12 volts one or more of the following may be the cause:

a. The battery charger is not charging the battery (poor connection or it is not working) or the charge rate is set to low.

b. The DLC-II does not have a good connection to the ICC reprogramming cable (not straight).

c. The ICC reprogramming cable does not have a good connection to the ICC control unit or the vehicle harness.

d. The DLC-II or ICC reprogramming cable may have a malfunction (damaged wire or pins).

e. The CONSULT-II Converter (J44200-50 / black box) is not working correctly (see Figure 15).

CAUTION:
^ Do not attempt ICC reprogramming if the vehicle's battery voltage is below 12 volts.

^ Permanent ICC damage can occur if the vehicle battery does not maintain the minimum voltage during ICC reprogramming.

^ If Charger Input is above 12 volts power from the vehicle battery will keep CONSULT-II's power supply at the correct level during reprogramming (see Figure 19).

^ If the charging voltage is too high (above 13.5 V) there may be a risk of damaging electrical components such as the ECU etc.

4. Continue with Section 4 below.

Section 4: Check CONSULT-II Converter version

1. Press [BACK] two times.





2. Press [INITIATE ECU REPROGRAM]





3. Press [CONSULT-II CONVERTER]





4. Press [CHECK VERSION]





^ If version "0018" is displayed continue with Section 5.

^ If any other version is displayed perform CONSULT-II Converter Update starting below.

CONSULT-II Converter Update (if needed)

1. Press [BACK] one time.





2. Press [C-II CONVERTER UPDATE]





3. Press [START]

^ As soon as START is pressed the CONSULT-II backlight will automatically turn OFF and the update will start.

NOTE:

4. This screen will be displayed when the update is successfully completed.

^ Backlight will automatically come ON.





^ Update result will automatically print.





^ If the update is not successfully completed the power LED on the CONSULT-II Converter will be OFF.

^ In this case the update needs to be performed again.

CAUTION:
When update errors are displayed on the screen the power LED may be ON even though the update did not complete. In this case the update needs to be performed again.

Section 5: Perform ICC Control Unit Reprogramming





IMPORTANT:
^ Make sure all electrical loads* are OFF (except for the ignition).

^ Reprogramming will take approximately 25 minutes.

CAUTION:
You must leave the vehicle and the CONSULT-II unit undisturbed (don't touch) until reprogramming is complete.

PLACE THE WARNING SIGN ON THE VEHICLE WHILE REPROGRAMMING IS IN PROCESS.

CAUTION DURING REPROGRAMMING:
^ Do not unplug CONSULT-II from the vehicle; permanent ICC damage can occur.

^ Do not open any door or the trunk during reprogramming.

^ On some vehicles the cooling fans may come on during reprogramming. This is a normal condition. Do not disconnect the cooling fans. Forgetting to reconnect them may cause severe engine damage (overheating). A vehicle battery charger is needed* to maintain the battery voltage level during reprogramming.

* You should have hooked up and a battery charger in Section 3.
