^ To prevent control module damage, do not operate anything electrical (audio system, brakes, A/C, power windows, moonroof, etc.) during the update.
^ The HDS screen may go dark during the update. This does not mean the update is finished. Tap the screen and the display will show the current status of the update.
^ Unless you are directed by the HDS, do not disconnect the HDS or turn the ignition switch off during the update.
^ Two updates are required: one for the PGM-FI system and one for the A/T.
1. Verify that the correct software is loaded into the HDS by selecting the icon in the lower left corner of the HDS start-up screen.
^ If the software version is 2.005.004 or later, go to step 2.
^ If the software version is earlier than 2.005.004, load the latest software, then go to step 2.
2. Update the vehicle's PGM-FI software and A/T software with the HDS. For updating information, refer to Service Bulletin 01-023, Updating Control Units/Modules.
