Service Procedure

Use the special reprogramming card titled "Air Bag Control Unit Service Campaign (P3156)" to reprogram the Air Bag Control Unit. See below for details.

[The following procedure should be performed by an OBDII Certified technician.]

Important Information About Air Bag Control Unit Reprogramming and The Special Reprogramming Card:
^ This is a special procedure just for this campaign.
^ Your dealership was supplied with the special reprogramming card for this campaign. The card was sent by way of Fed Ex to each dealer's Service Manager.
^ This card already contains all the software needed for this campaign. Data files are NOT available in ASIST.
^ If the special reprogramming card is inoperable contact the Technical Support Department.





1. Install the special reprogramming card Air Bag Control Unit Service Campaign (P3156) [Orange 16MB] into slot A of CONSULT-II (see Figure 1).

CAUTION:
Do NOT allow the vehicle's battery voltage to drop below 12.0 volts during reprogramming. Permanent damage can occur if the battery does not maintain minimum voltage during the reprogramming period.

2. Connect CONSULT-II to the vehicle making sure the connector is fully plugged in.

3. Confirm that all electrical loads (except for the ignition) such as headlights defroster A/C Audio (radio) cellular telephone etc. are "OFF".

CAUTION:
Do NOT unplug CONSULT-II from the vehicle while reprogramming. Do NOT attempt reprogramming with any vehicle electrical loads "ON" except for the ignition. Permanent damage can occur.

4. Turn the ignition switch "ON" but do not start the engine. CONSULT-II will turn ON automatically.





5. Press "SUB MODE" (see Figure 2) then select "BATTERY CHARGE".





6. Check the vehicle's battery voltage reading on the CONSULT-II screen (see Figure 3).

NOTE:
^ Confirm CONSULT-II is receiving suitable voltage from the vehicle's battery.
^ The vehicle's battery voltage is called "CHARGER INPUT" and MUST be above 12.00 volts when reprogramming.

CAUTION:
Do NOT allow the vehicles battery voltage to drop below 12.0 volts during reprogramming. Permanent damage can occur if the battery does not maintain the minimum voltage during the reprogramming period.

7. Press "BACK" (see Figure 3).





8. Press "START REPROGRAMMING FOR THE AIRBAG ECU" (see Figure 4).





9. Check the "CURRENT ECU DISCRIMINATED NUMBER" on the CONSULT-II reprogramming screen (see Figure 5):
^ If the "CURRENT ECU DISCRIMINATED NUMBER" is "FD02" or "FD03" the Air Bag Control Unit needs to be reprogrammed. Press "YES" on the Reprogramming screen (see Figure 5) to continue with the reprogramming (see step 10).

^ If the "CURRENT ECU DISCRIMINATED NUMBER" is "FD04" the Air Bag Control Unit does NOT need to be reprogrammed. Press "COPY" and attach the CONSULT-II screen printout to the Repair Order. Then press "NO".





10. Turn the ignition switch OFF and then back ON within 5 seconds. Then press "OK" (see Figure 6) to start Air Bag ECU reprogramming. It takes about 10 seconds to complete the reprogramming.





^ If the reprogramming is successful print out the CONSULT-II screen (see Figure 7) and attach it to the Repair Order then press "END".

^ If the reprogramming was NOT successful ("Communication Error Detected" message on the CONSULT-II screen) check the cables and connections then retry reprogramming (return to step 8).
