An important system in any vehicle is the Daytime Running Lamp Control Circuit, especially in GMC vehicles with the code B2600 00. GMC B2600 00 code ensures that the battery voltage is between 9-16 V and that the headlamp switch is in AUTO. The malfunction of this system can be caused by a short voltage in the DRL resistor control circuit and can drive a failure type with no sub-type information. To ensure the optimum performance of the GMC B2600 00 code and its associated Daytime Running Lamp Control Circuit, it is necessary to understand the causes and solutions for any issues.

Causes and Solutions for GMC B2600 00 Code
| Cause | Solution |
|---|---|
| Incorrect battery voltage | Check the voltage and replace the battery if necessary. |
| The headlamp switch is not in the AUTO position | Put the headlamp switch in the AUTO position. |
| Short to voltage in the DRL resistor control circuit | Inspect the circuit and replace any faulty components. |
| No Sub Type of Information | Check the manual for any additional information. |
Incorrect Battery Voltage
The GMC B2600 00 code requires that the battery voltage be between 9-16 V for proper functioning. If the voltage is not within this range, the Daytime Running Lamp Control Circuit will malfunction. To correct this issue, it is necessary to check the voltage and replace the battery if necessary.
Headlamp Switch Not in AUTO Position
Another common cause of malfunction in the GMC B2600 00 code is a headlamp switch not in the AUTO position. This can happen if the switch is moved manually or the vehicle is in a different mode. The switch must be manually set to the AUTO position to correct the issue.
Short to Voltage in the DRL Resistor Control Circuit
The GMC B2600 00 code can also malfunction due to a short to voltage in the DRL resistor control circuit. This issue can cause a failure type with no sub-type information. To correct the issue, inspecting the circuit and replacing any faulty components is necessary.

No Sub Type of Information
If the GMC B2600 00 code fails to provide sub-type information, it is important to check the manual for additional information. This can help identify the root cause of the issue and provide a solution.
Conclusion: Optimizing the GMC B2600 00 Code
The GMC B2600 00 Code is an important system in any GMC vehicle. Malfunctions of this system can be caused by incorrect battery voltage, the headlamp switch not being in AUTO position, short voltage in the DRL resistor control circuit, or no Sub Type Information. To ensure the optimum performance of the GMC B2600 00 Code and its associated Daytime Running Lamp Control Circuit, it is necessary to understand the causes and solutions for any issues. Understanding the causes and solutions for any problems makes it possible to ensure the best performance of the GMC B2600 00 Code.
