J2534 Software

American Honda Motor Co., Inc. offers SAE J2534 compliant reprogramming software for Honda and Acura vehicles FREE of charge. This J2534 software, when used with a properly built J2534 pass-thru device , will automatically check for the latest vehicle calibration information.

 

Important Notice

Do NOT program a control module unless you are directed by a service procedure or an applicable Honda/Acura Service Bulletin. Control Module updating should only be undertaken by a skilled professional using proper equipment and procedures, or module damage can occur. The process of updating to the latest software not associated with a specific symptom may not resolve other specific customer concerns. Unauthorized or self-directed programming may cause unintended and irreversible effects and lead to vehicle harm and/or customer dissatisfaction.

American Honda urges end users to always use the LATEST production release of the J2534 Honda Reprogramming software. Using the latest version of the software is the best way to ensure successful reprogramming of applicable control modules.

It is possible to damage the vehicle’s electronic control modules during reprogramming. Ensure the following conditions are met BEFORE programming a control module:

  • The vehicle battery must be fully charged before programming the control module. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming.
  • Turn OFF or disable any system that may put a load on the vehicle battery.
  • Make certain all tool connections are secure. Do NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.

THE ON-SCREEN REPROGRAMMING PROCEDURE MUST BE FOLLOWED EXACTLY AS OUTLINED BY THE SOFTWARE. FAILURE TO FOLLOW THESE INSTRUCTIONS WILL CAUSE THE REPROGRAMMING TO FAIL.

Some modules may require additional programming/setup events performed before or after programming. Please refer to the appropriate Service Bulletins for details. (e.g. IMA Battery Module)

The information in Service Bulletins is intended for use by trained, professional technicians with the knowledge, tools, and equipment to do the job properly and safely. The procedures should not be performed by “do-it-yourselfers”. American Honda reserves the right to supersede this information with updates. The most recent information is available through American Honda’s on-line technical resources.

 

Warning: Certain control module systems require special procedures and or hardware to be properly reprogrammed. Before proceeding ahead, check the vehicle list below.
