- Following the procedure outlined in the Suzuki Pass-Thru Reprogramming Tool Operator’s Manual, download and install the Pass-Thru Reprogramming Software “SOFTWARE.EXE” in your PC, (if it is not already installed).
- Follow the procedure in Section 3.2 of the Operator’s Manual to update the Database files. Download and unzip Suzuki Pass-Thru Reprogramming Data Base “DATABASE.EXE” in your PC. This step is only required to be done once to accommodate all vehicles covered under this TSB.
NOTE:
This Database “DATABASE.EXE” has been updated with newer data for reprogramming without changing the file name. You are requested to download in order to update the database in your PC.
- Following the procedures outlined in the Suzuki Pass-Thru Reprogramming Tool Operator’s Manual, hook up the SDS Interface Tool P/N 09910-06520 to the vehicle and run the ECM reprogramming software. Continue to step 6. If the message “[4028] ECU already has the latest version” appears, click “OK”. No further action is required. The glove box label should already be in the glove box.
- Fill out the Reprogram Label P/N 99963-01501-224 (the part number and version will be displayed at the “The reprogramming is successful” screen). Then affix the label to the back of the glove box door as pictured below.

Software and subscriptions to perform J-2535 pass thru programming depends on the vehicle to be programmed. Most Suzuki vehicles use the SEPS Suzuki ECU Programming System software subscription, except the 07-09 XL7 which used Tis2Web and the Equator which is not reprogrammable. The SEPS software subscription is $300 per year and the Tis2Web subscription offers 24 hour access for $35.
