The blah, blah, blah...is critical. There is a
specific drive cycle where FOUR criteria MUST BE performed to test all system to make them "ready".
In the chart below...you will see all FOUR criteria that must be accomplished (on the top half of the chart)....and what is typed on the lower half of the chart is the part of the emissions system that is being tested.
Unfortunately by the number of times it is asked...you do NOT have to follow each in the exact time limit. If you do the 1st step but it takes you longer to get to a stretch of road to perform the 2nd or 3rd step etc...then just make sure you do
NOT go over the
speed and RPM limit (given in the chart) and when you get to a stretch of road that allows you to perform the other 3 test...do so (following the criteria outlined in the chart):
- FTP Drive Cycle = the criteria covered in the chart below which when carried out will fulfill the OBD Readiness criteria
- Customer Drive Cycle = any driving event by the driver which may or may not fulfill "all" of the OBD FTP drive cycle criteria (usually not)
