PCM Trouble Codes Display

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