Code B2601 Description
The B2601 diagnostic trouble code (DTC) indicates that the Daytime Running Lights (DRL) relay control circuit is shorted to ground. The DRL system is responsible for automatically turning on the headlights at reduced intensity during the day to increase visibility for other drivers. When this circuit is shorted to ground, it means that there is an unintended connection between the relay control circuit and the vehicle's ground, leading to the malfunction of the DRL system.
Common Causes of B2601
- Corroded or damaged wiring in the DRL relay control circuit
- Faulty DRL relay
- Short circuit in the DRL wiring harness
- Water intrusion causing electrical connections to short to ground
- Previous accident or collision damaging the DRL system components
Symptoms of B2601
- Daytime running lights not working
- Headlights flickering or turning on and off unexpectedly
- Dashboard warning light indicating a lighting system malfunction
- Battery draining more quickly than usual
- Other electrical issues such as blown fuses related to the lighting system
How to Fix B2601
- Begin by conducting a thorough visual inspection of the DRL relay control circuit, looking for any damaged or corroded wiring or components. Repair or replace any faulty wiring or connectors.
- Test the DRL relay using a multimeter to determine if it is functioning correctly. Replace the relay if it is found to be faulty.
- Check for any signs of water intrusion in the DRL system components and address the issue to prevent future shorts.
- Clear the diagnostic trouble codes from the vehicle's computer using a scan tool after completing the repairs.
- Test the DRL system to ensure that it is functioning properly before returning the vehicle to service.
Cost to Fix B2601
The cost of repairing a DRL relay control circuit shorted to ground can vary depending on the extent of the damage, the specific vehicle make and model, and the labor rates in your area. On average, you can expect to pay between $150 to $300 for parts and labor to address this issue. Keep in mind that diagnostic time and labor rates at auto repair shops can fluctuate, so it is advisable to obtain quotes from multiple sources to get a more accurate estimate for your specific situation.

Frequently Asked Questions about B2601 Code
What does the OBDII code B2601 indicate?
1. Code B2601 indicates that the Daytime Running Light (DRL) Relay Control Circuit has a short to ground. This disrupts the proper operation of the DRL system. 2.
What are common symptoms of the B2601 code?
Common symptoms include DRLs not functioning, flickering lights, or the DRLs being stuck on when the vehicle is off. 3.
What causes the B2601 code to appear?
The main causes are damaged wiring, a faulty DRL relay, a short to ground in the circuit, or a malfunctioning body control module (BCM). 4.
Can I drive with the B2601 code active?
While the vehicle is usually drivable, driving without functioning DRLs can reduce visibility and safety, especially in low-light conditions. 5.
How do I diagnose the B2601 code?
Start by inspecting the wiring and connectors for damage or corrosion. Then test the DRL relay and check for a short to ground in the circuit using a multimeter. 6.
How can the B2601 code be fixed?
Repairs may include replacing damaged wiring, cleaning or replacing corroded connectors, installing a new DRL relay, or reprogramming/repairing the BCM if necessary. 7.
How much does it cost to fix the B2601 code?
Repairs can range from $50 to $300, depending on whether the issue involves simple wiring repairs or replacement of components like the DRL relay or BCM. 8.
Can a bad DRL relay cause the B2601 code?
Yes, a faulty DRL relay is a common cause of this code, as it can create a short to ground in the control circuit. 9.
Will resetting the code solve the issue?
Resetting the code may temporarily clear it, but the underlying issue must be repaired to prevent the code from returning. 10.
Is the B2601 code specific to certain vehicles?
This code is not specific to one make or model but is more common in vehicles equipped with DRL systems that use a relay for control. Check your vehicle's service manual for specific details.
