SOURCE: Low Beams Stay On

Also, the daytime driving lights are controlled by relay. It's possible the relay may have melted down inside and is shorted, remaining on even when primary ignition power is off. The relay runs about $15.00 to $20.00 USD and might be worth a shot to replace. Likely you can get one at a recycling yard for a dollar or two.

Do bcm need to be reprogramed


Has to be programmed ,yes .
Body Control Module (BCM) Replacement
If the BCM is replaced, the following procedures must be performed in the subsequent order:
• BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems for replacement, setup, and programming.
• Theft Learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent.

A new body control module (BCM) must be programmed with the proper regular production option (RPO) configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes, the BCM will not control all of the features properly. The Tech 2 software will automatically prompt you with the RPO available for the vehicle. Ensure that the following conditions exist in order to prepare for BCM programming:
• The battery is fully charged.
• The ignition switch is in the ON position.
• The data link connector (DLC) is accessible.
• All disconnected modules and devices are reconnected before programming.
To setup a new BCM, access the Vehicle Control Systems in Computer/Integrating Systems menu on the scan tool to program the BCM. Select Module Replacement/Setup and follow the instructions on the scan tool.
If the BCM fails to accept the program, perform the following steps:
• Inspect all BCM connections.
• Verify that the scan tool has the latest software version.

2000 yukon when head lights are on and the heater you turn hi beams and the heater turns to cold and blows in defrost mode and can't change the buttons u have to shut truck off to reset what's wrong


The first place to start with problems like this to try an reset the computers on the vehicle . Disconnect the battery cables an touch them together for five or ten min. Then if that doesn't work you need to have the vehicle checked out , which means having a factory or equivalent scan tool check for codes in the BCM !
The body control module (BCM) is capable of controlling multiple body functions. Components directly connected to the BCM are controlled by the BCM's outputs. The BCM controls the outputs based on input information that it obtains from the sensors and the switches that are directly connected to it. The BCM can also borrow information from other vehicle systems connected to the Class 2 serial data link. The BCM evaluates this information and controls certain body systems by commanding an output ON or OFF.
The BCM is also capable of commanding other vehicle systems to control functions that are not directly wired and/or controlled by the BCM. The BCM accomplishes this task by sending specific messages on the Class 2 serial data link. The vehicle system capable of performing such function will respond to the BCM message.
The BCM controls the following functions:
?€¢
Audible Warnings


?€¢
Indicator Warnings


?€¢
Interior Lighting


?€¢
Exterior Lighting.


?€¢
Power Door LOCK/UNLOCK


?€¢
Remote Keyless Entry


?€¢
Passlock Theft Deterrent

The problem is that the VIN an BCM numbers dont match. You are going to need a scan tool. Go into special functions setup from menu. Enter setup new BCM, do the same to the VIN SDM. If ithese numbers dont match an scan tool cant set it you will need to purchase a new BCM. Body Control Modual. It can be done but some vehicles dont allow it. May need a mechanic.

2005 avalanche Fog lights are staying on with


The fog lamps are computer controlled .the body control module (BCM) will energize the fog lamp relay control circuit. The BCM receives the park lamp ON signal from the interior park lamps supply voltage signal circuit.
DTC B2527 Front Fog Lamps Circuit Low
The body control module (BCM) monitors the front fog lamp switch signal circuit in order to determine when the fog lamp relay is to be energized. When the BCM senses that the front fog lamp switch signal circuit is grounded momentarily by pressing the fog lamp switch, the BCM energizes the fog lamp relay by grounding the fog lamp relay control circuit.

Your best bet , take it to the dealer . Could need BCM replaced , would need to do testing using the Tech 2 scan tool . A new BCM has to be programmed .

Body Control Module (BCM) Replacement
If the body control module (BCM) is replaced, the following procedures must be performed in the following order:
BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
Important: This procedure has to be performed only for vehicles equipped with the Passlock™ System.
Theft Learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent. A new BCM will learn the Passlock™ information automatically, but the powertrain control module (PCM) must still learn the theft information from the BCM.

Heater and AC and blower all work fine but it all blows out of defroster vents thats about it , when AC is on it comes out defroster vents,no matter your selection. Heater is the same way.


The HVAC mode selections on these are controlled by an electric stepper motor that receives commands from the BCM (body control module). The BCM decides where the air door should be by looking at where the dash control input is.
Each mode selected has a different resistance level. From low resistance to high resistance: Panel, Bi-Level, Floor, Mix and Defrost, with Defrost as the highest resistance (~100K ohms). A high resistance or open circuit would probably default the system to defrost no matter what position the mode control was set to.
If the control is dirty or there is a connection issue, this could cause this problem. Does playing with the control make any difference?
The BCM can store fault codes with HVAC releated information. The system can be reset and recalibrated with a battery disconnect, this will also erase any fault codes.
I would start by looking at the dash mode control.

Good luck, i hope this helps.

All interior dome light are out on 2004 quest, fuse checked are good


The interior light are controlled by the Body Control Module (BCM).
Check the fuse for the BCM. If the fuse is OK, then try to disconnect the car battery for about 10 minutes to reset the BCM. If resetting the BCM doesn't work you may have to replaced it.
