2. Does "customer drive cycle" mean...
a) customers following the specified drive cycle exactly?
b) customers following the specified drive cycle as closely as possible?
c) customers' normal driving?

1. FTP = Federal Test Protocol
2. Customer drive cycle means - "C"
A customer's drive cycle is what they may do under their normal daily driving route. This route or "cycle" may not create the conditions for all monitors to be tested...thus the FTP (federal test protocol) has its defined "FTP drive cycle" where all of the monitors should be tested within its defined criteria.
You'll discover reading through many threads on this topic where owners will mention that they drove for hours or over 100 miles etc and the monitors still aren't ready. And when you consider the last test (idle for 5 minutes
IN GEAR)...how many examples of daily driving does that occur...unless you are stopped at a railroad crossing or REALLY long light? This is an example of a "customer's drive cycle" versus the "FTP drive cycle". The FTP drive cycle can be completed in approx 30 minutes of driving if there aren't any other underlying issues.
