What is the B1568 Lamp Headlamp High-Beam Circuit Open Error Code?

The B1568 error code is a diagnostic trouble code (DTC) that indicates a problem with the headlamp high-beam circuit. This code is specific to Ford vehicles and is often caused by a faulty headlamp switch or a damaged wiring harness. When this error code appears, the high-beam headlights may not work properly, which can be a safety hazard while driving at night.

Diagnosing the B1568 Error Code

To diagnose the B1568 error code, you’ll need a few tools, including a digital multimeter and a wiring diagram for your vehicle. Here are the steps to follow:

Step 1: Check the Headlamp Switch

The first step is to check the headlamp switch. Start by turning on the headlights and checking if the high-beam headlights are working. If they’re not, turn off the headlights and remove the headlamp switch from the dashboard. Use the multimeter to check the continuity of the switch. If the switch is faulty, replace it with a new one.

Step 2: Check the Wiring Harness

If the headlamp switch is not the problem, the next step is to check the wiring harness. Use the wiring diagram to locate the high-beam circuit wires and check for continuity using the multimeter. If there’s no continuity, there may be a break in the wiring harness. Check for any visible damage to the wiring and repair or replace any damaged wires.

Step 3: Check the High-Beam Relay

If the wiring harness is not the problem, the high-beam relay may be faulty. Use the wiring diagram to locate the high-beam relay and check for continuity using the multimeter. If there’s no continuity, replace the relay with a new one.

Solving the B1568 Error Code

Once you’ve diagnosed the problem, it’s time to solve the B1568 error code. Here are the steps to follow:

Step 1: Replace the Faulty Component

If you’ve identified a faulty component, such as the headlamp switch or the high-beam relay, replace it with a new one. Make sure to use the correct replacement part for your vehicle.

Step 2: Repair or Replace the Wiring Harness

If there’s a break in the wiring harness, repair or replace the damaged wires. Make sure to use the correct gauge wire and connectors for your vehicle.

Step 3: Test the High-Beam Circuit

Once you’ve replaced the faulty component or repaired the wiring harness, test the high-beam circuit to make sure it’s working properly. Turn on the headlights and check if the high-beam headlights are working. If they’re not, recheck your work and make sure everything is connected properly.
