How Autel AL519 check Chevrolet Silverado 2500 pickup engine code?

Today I am going to demonstrate how use Autel AL519 scanner to check engine code for my dad’s Chevrolet Silverado 2500 pickup. I tested it OK last weekend to read fault code and finally reset the check engine light.

The story was that: my dad’s pickup truck got a check engine light, so I tried to use the AL519 scanner to distinguish where was the problem. And I did it! AL519 read out the engine code P0455 and then I found out the problem easily: there was something wrong with the gas cap.

Autel AutoLink AL519, it is original but cheap. I got it from wobd2.com only $69, sent directly from UK. (And they also have US and Australia warehouse available.)

1. Let’s talk to the point. Below are steps about how I did it:

First, connect AL519 to car’s OBD2 port. It’s underneath the driver side.

Next, choose “OBDII” function

It show me system status

I press “OK” button and it ask me to erase the stored code? I choose “Yes”

Then I choose “Read Codes” option

Choose “Stored Codes”

And it show me the engine code: P0455 Evaporative emission system leak

I find out there must be some issues on the gas cap. And I am correct, the gas cap is loose. So I make it a good seal and the check engine light soon disappears!

That’s all about my review and test of Autel AL519. I am happy with it and hope it also helps you!
