im looking at a 99 el dorado. as i learned from other members here, i held the off and warmer buttons to check for any error codes. Three came up, but they all said "History." I'm assuming that means those were codes that had popped up in the past, but were resolved. Is that correct?
The three codes were IRC B1771, IRC U1255, and MSM B2116. Anybody have info on them?
Also, after it read those, the screen displayed "PCM?" What's that about?
