Info up, and on/off pushed together and held will get you a segment check followed by 'ALL?' on the info center. Info up/down will scroll through available modules alphabetically, locate PCM? and push on/off. It will either read PCM CODES?, or PCM CLEAR CODES?. Either way, info button will get you to the clear codes display, then push on/off. You should get PCM CODES CLEAR, and just shut the key off, or hit any button on the LH side. I typically use eng/met, but it makes no difference.
