Help with failed smog

[BizzyB]

Hi
I have a 15 with 59k miles.
I just had 2 recalls done egr cooler and crankshaft position. The dealer also updated to a newer software version. I took my truck for smog and it passed all emissions but failed due to enough driving history ?do you know how many miles I need to drive and at what speeds ?
thank you

Drive it 50 miles without shutting it off. Make sure you get it up to temp for most of that 50 miles.

CA smog check?

 

[BizzyB]

Yes
And thank you

Some of your I/M readiness monitors aren’t set.

You need to do a DRIVE CYCLE to set the Monitors
Hit the Hwy at night if your not out in the country
