How to Diagnose and Solve B1587 Autolamp Delay Increase Circuit Failure Issues
Introduction
As a car owner, you may have experienced issues with your car’s lighting system. One of the most common issues is the B1587 Autolamp Delay Increase Circuit Failure. This issue can be frustrating, especially when you need to drive at night or in low-light conditions. In this article, we will discuss how to diagnose and solve this issue.
What is B1587 Autolamp Delay Increase Circuit Failure?
B1587 Autolamp Delay Increase Circuit Failure is a fault code that appears on the car’s diagnostic system. This code indicates that there is a problem with the autolamp delay increase circuit. The autolamp delay increase circuit is responsible for controlling the delay time of the car’s lighting system. When this circuit fails, the car’s lighting system may not work properly.
Diagnosing B1587 Autolamp Delay Increase Circuit Failure
To diagnose B1587 Autolamp Delay Increase Circuit Failure, you will need a diagnostic tool. Connect the diagnostic tool to the car’s OBD-II port and read the fault codes. If the fault code B1587 appears, it means that there is a problem with the autolamp delay increase circuit.
Checking the Autolamp Delay Increase Circuit
To check the autolamp delay increase circuit, you will need a multimeter. Set the multimeter to measure voltage and connect the positive lead to the autolamp delay increase circuit’s positive terminal. Connect the negative lead to the negative terminal. Turn on the car’s ignition and check the voltage reading. The voltage reading should be between 12V and 14V. If the voltage reading is lower than 12V, there may be a problem with the circuit.
Checking the Autolamp Delay Increase Relay
If the autolamp delay increase circuit is working correctly, the next step is to check the autolamp delay increase relay. The relay is responsible for controlling the autolamp delay increase circuit. To check the relay, you will need a multimeter. Set the multimeter to measure resistance and connect the positive lead to the relay’s positive terminal. Connect the negative lead to the negative terminal. The resistance reading should be between 50 and 100 ohms. If the resistance reading is higher than 100 ohms, there may be a problem with the relay.
Solving B1587 Autolamp Delay Increase Circuit Failure
Once you have diagnosed the issue, it’s time to solve it. The first step is to replace the autolamp delay increase relay. You can purchase a new relay from your local auto parts store. Once you have the new relay, disconnect the old relay and replace it with the new one.
Testing the Autolamp Delay Increase Circuit
After replacing the relay, it’s time to test the autolamp delay increase circuit. Connect the multimeter to the circuit and turn on the car’s ignition. Check the voltage reading. The voltage reading should be between 12V and 14V. If the voltage reading is within this range, the issue has been solved.
Conclusion
B1587 Autolamp Delay Increase Circuit Failure can be a frustrating issue for car owners. However, with the right tools and knowledge, it can be diagnosed and solved quickly. By following the steps outlined in this article, you can diagnose and solve this issue and get back on the road safely.
