the HPPIII should walk you through everything and it should go something like this
Plug the Hypertech in and turn it on
Turn the key to on/accessories when prompted
Once all the vehicle identification stuff finishes, it should read something like "checking for diagnostic trouble codes" (DTC's)
It'll scan your system and report how many you have (if you hve any) and give you the option to view them Y to view N to not
(you'll get a prompt to write them down)
Next it'll show you the DTC's you have one at a time(copy them down)
Then it will say something like "would you like to view DTC's again?" press Y if you would N if you don't
Somewhere along here it'll say DTC's must be cleared to enter Power Programming mode, do you want to clear DTC's Y for yes N for no
Hit Y, they erase, and it clear's the SES light
Last thing it does is ask you if you want to exit the program or enter into the Power Programmer mode. you can exit now.
Let the HPPIII turn off
Unplug the HPPIII, turn key off, wait 30 seconds to a minute, and start the engine.....the SES light should be gone.
