Notes

2) E800 v1.0 to v1.1 uses alarm condition code 4 as a “Controlled Shutdown alarm ”



Page 155 – Previous ECU Trouble Codes

 

  1. Currently supported in 73xx modules.
  2. Functionally identical to page 142 but will return trouble codes that have been previously active (if supported by the engine file). Page 142 returns codes that are currently active.
  3. Reading register 0 effectively latches a copy of the trouble code list at that time and so allows the list to be read without risk of the contents changing until register 0 is re-read. This also applies to reading the short descriptive strings for the trouble codes (see following pages), so that the list of trouble codes can be read in one or more sections and then the associated strings read as needed. To see any updates to the list, the PC needs to re-read register 0 and so latch the list once more.
