Can I use a used body control module?

There are a few potential causes for this issue with the driver's heated seat in your 2013 F150 F150 FX4:

1. Faulty seat control module: The seat control module is responsible for controlling the heating and cooling functions of the seat. If it is faulty, it may cause the seat to function improperly.
2. Wiring issue: There may be a problem with the wiring that connects the seat control module to the seat heating and cooling elements.
3. Faulty seat heating and cooling elements: The heating and cooling elements in the seat may be faulty and not functioning properly.

To fix this issue, you will need to diagnose and troubleshoot the problem. This may involve checking the wiring, testing the seat control module, and inspecting the seat heating and cooling elements. It is recommended to have a mechanic or dealership technician diagnose and fix the issue, as they will have the necessary tools and expertise to properly troubleshoot and repair the problem.

Your vehicle has electric power steering
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, nor the EPS motor are serviced separately from each other or from the steering column. Ant EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.

Doesn't use power steering fluid ,your vehicle has electrric power steering . What's the problem ? Light or message on instrument cluster ? SERVICE POWER STEERING

eps ???? spell it out electric power steering (EPS) system ? The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, nor the EPS motor are serviced separately from each other or from the steering column. Ant EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.
The scan tool won't communicate with what ? The power steering control module , BCM or PCM/ECM .

What's wrong ? light on ? Have it checked for codes ? GM had recall for the cobalt . Do you know it has electronic power steering ?

Body Control Module (BCM) Replacement and Reprogramming
If the BCM is replaced or requires reprogramming, the following procedures must be performed in the specified order:
BCM Setup -- Using a scan tool, go to Vehicle Control Systems » Computer/Integrating Systems » Module Setup » Body Control Module. Select Setup BCM and follow the on-screen instructions, making sure to select the proper RPOs and input the VIN correctly.
BPP Sensor Calibration--Refer to Brake Pedal Position Sensor Calibration
Program Key Fobs--Refer to Transmitter Programming
Setup SDM Part Number in BCM -- Using a scan tool, go to Vehicle Control Systems » Computer/Integrating Systems » Module Setup » Body Control Module. Select Setup SDM Part Number in BCM and follow the on-screen instructions.

Hey Alex , what would you like to know ? Your vehicle has Electronic power steering , controlled by a control module .
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle.

They had a recall on these systems ! Suggest you take it to a GM dealer , Chevy , Cadillac , Buick , etc.....

Before replacing parts there is a specific way to start diagnostics an a professional grade scan tool is a must ! a code reader can not access the body control module , or the EBCM - electronic brake control module or instrument cluster ! All these modules communicate on the class 2 serial data bus.
Begin the system diagnosis with Diagnostic System Check - ABS . The Diagnostic System Check will provide the following information:
?€¢
The identification of the control modules which command the system

?€¢
The ability of the control modules to communicate through the serial data circuit

?€¢
The identification of any stored diagnostic trouble codes (DTCs) and their status

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.
The traction control switch is a input to the body control module, with a scan tool hooked up an looking at BCM data ,check for conformation the traction control switch is turning on an off !
SERVICE TRACTION SYSTEM The IPC illuminates the SERVICE TRACTION SYSTEM indicator in the message center when the electronic brake control module (EBCM) detects a malfunction in the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination. The SERVICE TRACTION SYSTEM indicator illuminates for 60 seconds when the condition is present. The IPC sends a class 2 message to the radio in order to activate an audible warning.
TRAC OFF The IPC illuminates the TRAC OFF indicator when the following occurs:
?€¢
The electronic brake control module (EBCM) inhibits the traction control system due to a malfunction in the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination.

?€¢
The body control module (BCM) detects that the traction control switch has been pressed (signal circuit is low). The BCM sends a class 2 message to the EBCM in order to disable traction control. The IPC receives a class 2 message from the EBCM requesting illumination. The BCM sends a class 2 message to the radio in order to activate an audible warning.

The motor an EPS - electric power steering module have to be replaced together . The module needs to be programmed , Dealer ! Could be a steering angle sensor also . Could have DTC'S - diagnostic trouble code's stored .
