PCM Trouble Codes Display

Following one-second display of "8.8.8.", "E" appears on FDC. "E" indicates 2 passes through PCM trouble code display cycle are about to begin. First pass through PCM trouble code cycle displays trouble codes stored in memory, including history and current trouble codes; second pass displays only current trouble codes.
History trouble codes are those set in response to a malfunction that occurred during past 50 key cycles but not during present key cycle. Current trouble codes represent malfunctions currently taking place. All trouble codes displayed during this cycle are prefixed by "E". If no "E" codes are present, display will be by-passed.
Immediately following first pass through cycle of PCM trouble codes, second pass begins, during which only current trouble codes are displayed. These codes are prefixed by "E.E.", indicating related malfunction is currently taking place.
