Safety Improvement Campaign - Fit SRS Unit Reprogramming (07-011)

SAFETY IMPROVEMENT CAMPAIGN - FIT SRS UNIT REPROGRAMMING

TECHNICAL SERVICE BULLETIN

BACKGROUND

Last year, the 2007 Fit received a top rating of five stars in frontal-impact crash testing conducted by the National Highway Traffic Safety Administration (NHTSA). However, testing done later by the Insurance Institute for Highway Safety (IIHS) found that front airbag deployment could occur a fraction of a second earlier than normal under certain conditions. To enhance front airbag performance, Honda is conducting a safety improvement campaign involving the reprogramming of SRS control units.

CUSTOMER NOTIFICATION

All owners of affected vehicles will be sent a notification of this campaign. An example of the customer notification is at the end of this service bulletin.

To verify vehicle eligibility, check for at least one of these items:

• The customer has a notification letter.
• The vehicle is shown on your campaign responsibility report.
• The vehicle is shown as eligible on a VIN status inquiry.

In addition to these verification items, check for a punch mark above the first character of the engine compartment VIN. A punch mark in that location means this campaign has already been completed.

Some vehicles affected by this campaign may be in your new vehicle inventory. These vehicles must be repaired before they are sold or leased.

CORRECTIVE ACTION

Install the SRS software CD-ROM into an i  N workstation computer (a one-time operation), then reprogram the SRS unit. The tool used to reprogram 2007 Fit SRS units is the Fit SRS Cable Kit.

When connected to the vehicle's DLC (data link connector), the Fit SRS Cable Kit scans the SRS unit software and reprograms it by changing the calibration for front airbag deployment.

To reprogram a Fit SRS unit, you need the Fit SRS Cable Kit, the vehicle you're working on, and an i  N workstation computer.
