My name is ***** ***** I will assist you with your question today.

I'm an independent contractor and I don't get paid until a rating has been made.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

I apologize on the late reply. This looks to have been in the wrong category and it was moved over just a few minutes ago.

To understand you correctly, you are getting the flash codes, but it only happens when the A/C is on?

CLICK HERE for the flash code list. As you can see, you have a cylinder 1/2 fault as well as a engine retarder solenoid fault on the engine. I suggest having the CAT ET put onto the truck to narrow the code down and to test the injectors/solenoids on the engine.


You want a 5 star service and I want to provide a 5 star service. Please consider that I don't know your skill level as well as I can't see, touch, smell, hear the vehicle/machine in question. Please provide as much detail as possible and I will provide as much back.

Once an answer is provided, you should see a rating screen. Please rate my personal service to you. The ratings are my personal feedback, they are not the site feedback.

Thank you for allowing me to assist you through Just Answer!
