Code B2661 Description
The B2661 diagnostic trouble code (DTC) indicates that there is a short to battery voltage in the park lamp relay output circuit. This means that there is an abnormal connection that is causing the park lamp relay to receive constant power from the battery, even when it should not be activated. The park lamp relay is responsible for controlling the operation of the park lights on the vehicle. When this circuit is shorted to battery voltage, it can lead to various issues with the park lights, affecting the visibility of the vehicle to other drivers, especially in low-light conditions.
Common Causes of B2661
- Faulty park lamp relay
- Short circuit in the wiring harness
- Corrosion in the electrical connections
- Faulty body control module
- Electrical component failure
Symptoms of B2661
- Park lights staying on constantly
- Park lights not turning on at all
- Battery draining quickly
- Dashboard warning light illuminated
How to Fix B2661
- Begin by visually inspecting the wiring harness and connections for any signs of damage, corrosion, or loose connections.
- Use a multimeter to test the continuity of the park lamp relay output circuit to identify the location of the short to battery voltage.
- If the issue is with the park lamp relay, replace it with a new relay following the manufacturer's guidelines.
- Repair any damaged wiring or connections in the circuit to ensure proper functionality.
- Clear the DTC with a scan tool and test the park lights to verify that the issue has been resolved.
Cost to Fix B2661
The typical repair costs for addressing a B2661 code can vary depending on the specific cause of the issue and the labor rates in your area. On average, the cost of parts for a new park lamp relay can range from $20 to $50. Labor costs can vary but are typically between $80 and $150 per hour. Additional costs may apply if there are other underlying issues that need to be addressed. It is recommended to consult with a professional mechanic to get an accurate estimate for your specific vehicle.

Frequently Asked Questions about B2661 Code
1. What does the OBDII code B2661 mean?
B2661 indicates a "Parklamp Relay Output Short to Battery," meaning there is an electrical issue where the parklamp relay output circuit is shorted directly to the battery voltage.
2. What are the common symptoms of the B2661 code?
Common symptoms include parklamps staying on constantly, malfunctioning exterior or interior lights, drained battery, or a blown fuse.
3. What causes the B2661 code to trigger?
The code is typically caused by a short circuit in the parklamp wiring, a faulty parklamp relay, damaged connectors, or corrosion in the electrical system.
4. Can the B2661 code drain my car battery?
Yes, since the parklamps may remain on due to the short circuit, this can lead to battery drain if the issue is not resolved.
5. How do I diagnose the B2661 code?
Start by inspecting the parklamp relay and its wiring for damage or corrosion. Use a multimeter to check for continuity and trace any short circuits in the circuit.
6. Can I fix the B2661 code myself?
If you're comfortable with electrical diagnostics, you can inspect and repair damaged wires, replace the parklamp relay, or clean corroded connections. Otherwise, seek professional help.
7. Is it safe to drive with the B2661 code?
Driving with this code may not immediately harm the vehicle, but unresolved electrical shorts can lead to further damage or safety issues, such as battery failure.
8. How much does it cost to repair the B2661 code?
Repair costs vary depending on the specific issue, but replacing a parklamp relay typically costs $20-$50, while resolving wiring issues can cost $100-$300 or more if professional labor is required.
9. Can a blown fuse cause the B2661 code?
A blown fuse may indicate an underlying short circuit in the parklamp circuit, which can trigger the code. Replacing the fuse without addressing the short will likely cause it to blow again.
10. Will resetting the code fix the problem?
Clearing the code without repairing the underlying issue will not resolve the problem, and the code will likely return. Proper diagnosis and repair are necessary.
