Now that we know what the B2599 code means and its symptoms, let’s move on to diagnosing the problem.

Step 1: Check the Tailgate Release Switch

The first thing you should do is check the tailgate release switch. If it’s not working, it could be the cause of the problem.

Step 2: Inspect the Wiring

Next, inspect the wiring of the tailgate release system. Look for any signs of damage, such as frayed wires or loose connections.

Step 3: Test the PCM

If the switch and wiring are fine, the problem could be with the PCM. You can test it using a multimeter.

Solving the B2599 Tailgate Release Open Circuit Issue

After diagnosing the problem, it’s time to solve it. Here’s how:

Step 1: Replace the Tailgate Release Switch
