2007 Fit - From VIN JHMGD3...7S000001 thru JHMGD3...7S029966
Safety Improvement Campaign: Fit SRS Unit Reprogramming
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 IN 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 IN workstation computer.

^ For questions about loading the SRS software CD-ROM or using the Fit SRS Cable Kit, call American Honda Special Tools.
LOADING THE SRS SOFTWARE CD
NOTE:
^ Before reprogramming 2007 Fit SRS units, the SRS software CD-ROM must be installed on your IN workstation computer. It cannot be installed on your dealership's master computer and downloaded to the IN workstation computer. Software installation is needed only once.
^ Make sure the display properties of the iN computer are not set to the color black. If they are, you will not be able to see or follow the entire reprogramming sequence.
^ Use an iN computer that can be placed close to the vehicle needing SRS unit reprogramming.
^ For successful reprogramming, the iN computer's operating system must be Windows 2000 or Windows XP.
1. Close any programs currently running on the iN computer.
2. Insert the SRS software CD-ROM into the computer's CD-ROM drive.
3. At the lower left corner of the screen, click on Start.
4. From the Start menu, click on Run.
5. From the Run menu, click on Browse.
6. From the Browse menu, click on Setup.exe, then click on OK and click on Finish.
7. At the Fit Recalibrate installation successful screen, click on OK.
NOTE:
Close the Start Menu screen if it appears over the Fit Recalibrate installation successful screen.
8. At the FTDI CDM Drivers have been successfully installed screen, click on OK.
9. Once the software is loaded, remove the CD-ROM, store it in a safe place, then go to REPAIR PROCEDURE.
REPAIR PROCEDURE
NOTE:
^ Before you begin, read this entire procedure.
^ Make sure the battery is fully charged (13.6 volts). If the battery voltage drops below 10.0 volts or rises above 14.0 volts, the SRS unit reprogramming may fail.
1. Turn the ignition switch to ON (II), and watch the SRS indicator. The indicator should go off after 7 seconds to let you know there are no SRS DTCs. If the indicator does not go off, use the HDS to retrieve and clear the DTC(s). The SRS unit cannot be reprogrammed if there are any SRS DTCs.
2. Position the iN computer as close as possible to the driver's seat of the vehicle.
3. Attach the cables to the converter box:
^ Connect the small end of the DLC cable to the box.
^ Connect the square end of the USB cable to the box.
4. Connect the other end of the USB cable to the USB port on the iN computer.
5. At the lower left corner of the computer screen, click on Start.
6. From the Start menu, select Programs, and then select Fit _Recalibrate.
7. Input your dealership name, your name, and the VIN. With the specific VIN, the system can tell whether or not the SRS unit needs reprogramming.
8. Make sure the output file reads C/Fit_Recalibrate/LogFile.out, then click on OK.
9. When the screen changes, make sure it says VIN APPROVED, then select Reprogram SRS. If the screen does not say VIN APPROVED, recheck to make sure you input the correct VIN.
10. With the ignition switch in LOCK (0), connect the large end of the DLC cable to the vehicle's DLC (data link connector) under the dashboard.
11. When the Connect Tool to Vehicle and Turn Key to IGN ON box appears, turn the ignition switch to ON (II) and click on OK.
12. When the message Vehicle Needs to be Updated appears, click on OK. If the message Vehicle Does Not Need to be Updated appears, the update was already completed. If this is the case, go to step 15.
NOTE:
If a communication error occurs, you may need to reconfigure the COM port. Go to COM PORT RECONFIGURATION.
13. When the Recalibrations Completed message appears, click on OK.
14. Click on the Quit button to exit the program. Disconnect the cable from the DLC.
15. To complete the procedure, center-punch a completion mark above the first character of the engine compartment VIN.
COM PORT RECONFIGURATION
NOTE:
This procedure is needed only if there is a communications error during reprogramming.
1. Make sure the SRS cable kit's USB cable is properly connected to the iN computer and to the converter box.
2. From the Start menu, select Settings, and then click on Control Panel.
3. From the Control Panel screen, double-click on Systems.
4. From the System Properties menu, click on Hardware.
5. From the Hardware menu, click on Device Manager.
6. Click on Ports, and see if the Communications Port is set to COM1.
^ If COM1 is set, the COM port is correct.
^ If COM1 is not set, go to the next bullet point.
7. From the Ports menu selection, double-click on Communications Port.
8. From the Communications Port Properties menu, click on Port Settings, then click on Advanced.
9. From the Advanced Settings menu, change the COM Port Number to COMi.
