Question "2005 gmc z71 4 wheel drive"

i just today bought this truck. It is used with 64,000 miles with no warranty. After i drove it 10 mile to the house and picked up my things. I left headed to my daughters. Approx 3 miles from the house the check engine light came on. From what i can tell from the internet, i have to have a scanner to read the code. My question is: Do i have to have a scanner, or can a blink code be retrieved by crossing pins in the data connector?
