PCM Updating and Substitution for Testing

Special Tools Required
^ Honda diagnosis system (HDS) tablet tester
^ Honda interface module (HIM) and an iN workstation with HDS and CM update software
^ HDS pocket tester
^ GNA600 and an iN workstation with HDS and CM update software

Use this procedure when you have to substitute a known-good PCM in a troubleshooting procedure. Update the PCM only if the PCM does not already have the latest software loaded.

NOTE: Do not turn the ignition switch to LOCK (0) while updating the PCM. If you turn the ignition switch to LOCK (0) before completion, the PCM can be damaged.
