Ignition source
Ignition source codes: 2009 to 2027
What started it. Renumbered, with new sources added; none were deleted.
80 codes changed number and nothing else. 3 changed meaning as well — the OFM revised what they cover, or moved them to another group. 23 are new. None were deleted.
106 codes
New number only means the code kept its meaning — remap it and your history holds. The other four are the ones worth reading.
