Reprogramming Procedure:
1. Log onto the Suzuki Connect and access the Suzuki Pitstop.
2. Download and review the Suzuki Pass-Thru Reprogramming Tool Operator's Manual. This must be read and understood COMPLETELY before attempting to reprogram the ECM.
3. 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).
4. 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.
5. 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.
