Reprogramming Procedure

1. First check the Reprogramming label in the glove box to see what Version Number is present. If it shows Version Number 1BNH, 1BNL, 1BNF or 1BNJ do not continue, the reprogramming has already been done. If not continue to the next step.
2. Log onto the SCAT system and access the Suzuki Pitstop.
3. 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.
4. Following the procedure outlined in the Suzuki Pass-Thru Reprogramming Tool Operator's Manual, download and install the Pass-Thru Reprogramming Software "3_SOFTWARE.EXE" if it is not already installed. 
5. Download and unzip Suzuki Pass-Thru Reprogramming Data Base "4_DATABASE1.EXE" onto your PC. Follow the procedure in Section 3.2 of the Operator's Manual to update the Database files. This step is only required to be done once to accommodate all vehicles covered under this TSB.
   NOTE: This Database "4_DATABASE1.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.
6. 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 7.

   If the message "[4028] ECU already has the latest version" appears, click "OK" and "Finish". Check that the Database has been properly installed, see step  5. Try reprogramming again. If after installing the Database properly code 4028 appears again, no further action is required.
