Attachment III - Technical Information

OVERVIEW

Before demonstrating or delivering any of the vehicles involved in this recall, dealers are to reprogram the Restraint Control Module (RCM) to the latest calibration using IDS release 81.02 or higher. This new calibration will activate the passenger side air curtain as needed, even when the front passenger seat is empty.

SERVICE PROCEDURE

Important Information For Module Programming

NOTE:
When programming or reprogramming a module, use the following basic checks to ensure programming completes without errors.

^ Make sure the vehicle's battery is fully charged before carrying out the programming steps and connect IDS/scan tool to a power source.

^ Inspect Vehicle Communication Module (VCM) and cables for any damage. Make sure scan tool connections are not interrupted during programming.

^ A hardwired internet connection is strongly recommended.

^ Turn off all unnecessary accessories (radio, heated/cooled seats, head lamps, interior lamps, HVAC system, etc.), close doors.

^ Disconnect/depower any aftermarket accessories (remote start, alarm, power inverter, CB radio, etc.).

^ Disconnect/depower any aftermarket accessories (remote start, alarm, power inverter, CB radio, etc.).

^ Follow all scan tool on-screen instructions carefully.

^ Disable IDS/scan tool sleep mode, screensaver, hibernation modes.

^ Create all sessions Key On Engine Off (KOEO). Starting the vehicle before creating a session will cause errors within the programming inhale process.

Module Reprogramming

NOTE:
Reprogram appropriate vehicle modules before performing diagnostics and clear all Diagnostic Trouble Codes (DTCs) after programming. For DTCs generated after reprogramming, follow normal diagnostic service procedures. The diagnosis of fault codes stored in the RCM are not covered by this recall.

1. Reprogram the RCM to the latest calibration using IDS release 81.02 or higher. Calibration files may also be obtained at the website.

Recovering an RCM when programming has resulted in a blank module: NEVER DELETE THE ORIGINAL SESSION!

1. Obtain the original IDS that was used when the programming error occurred during Module Reprogramming (MR).

2. Disconnect the VCM from the data link connector (DLC) and the IDS.

3. Reconnect the VCM to IDS and then connect to the DLC. Once reconnected, the VCM icon should appear in the corner of the IDS screen. If it does not, troubleshoot the IDS to VCM connection.

4. Locate the ORIGINAL vehicle session when programming failed. This should be the last session used in most cases. If not, use the session created on the date that the programming failed.

NOTE:
If the original session is not listed in the previous session list, click the ''Recycle bin'' icon at the lower right of the previous session screen. This will load any deleted sessions and allow you to look through them. Double-click the session to restore it.

5. Once the session is loaded, the failed process should resume automatically.

6. If programming does not resume automatically, proceed to the Module Programming menu and select the previously attempted process.

7. Follow all on-screen prompts/instructions.

8. The last screen on the IDS may list additional steps required to complete the programming process. Make sure all applicable steps listed on the screen are followed in order.
