Hey guys, I'm having a problem with a parasitic drain. I haven't done a test, but I did scan it for codes and b1480 and b2610 came up. Could these codes cause the drain? If so, how should I go about fixing it? Thanks so much!

The b1480 code is the Battery Rundown Protection is not working so yes this will cause the battery to run down. You will need to replace the BCM here are the instructions in the images below.

Here is how you set the new BCM up:

BODY CONTROL MODULE (BCM) PROGRAMMING/RPO CONFIGURATION

INTRODUCTION
The procedures below are designed to set-up the body control module (BCM) correctly during BCM related service. Before you start, read these procedures carefully and completely.

IMPORTANT: The following procedures must be followed:
1. Programming the BCM.
2. Programming Theft Deterrent System Components, if equipped with Pass lock System.

PROGRAMMING THE BCM

IMPORTANT: After the procedure is completed, the personalization settings of the BCM are set to a default setting. Inform the customer that the personalization must be set again.
Perform the BCM special function Request BCM Info. For service programming system (SPS), then follow the SPS instructions. Refer to Service Programming System (SPS) in Programming.

PROGRAMMING THEFT DETERRENT SYSTEM COMPONENTS

IMPORTANT: This procedure has to be performed only for vehicles equipped with Pass lock System.

Perform the Programming Theft Deterrent System Components in Theft Deterrent after successfully finishing the Setup New BCM procedure. If the Programming Theft Deterrent System Components in the Theft Deterrent procedure is not performed after a BCM replacement, one of the following conditions will occur:
- The vehicle will not be protected against theft by the PASSLOCK system.
- The engine will not crank or start.

IMPORTANT: After programming, perform the following to avoid future misdiagnosis:

1. Turn the ignition OFF for 10 seconds.
2. Connect the scan tool to the data link connector.
3. Turn the ignition ON, with the engine OFF.
4. Use the scan tool in order to retrieve history DTCs from all modules.
5. Clear all history DTCs.

Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.
