How to Reset Your Car’s Driver Seat Module for Personalized Comfort

Modern vehicles come equipped with a variety of advanced features to enhance driver comfort and convenience. One such feature is the ability to save personalized driver seat settings using the Driver Seat Module (DSM). This allows multiple drivers to quickly recall their preferred seating position, mirror angles, and other customized settings with the push of a button.

However, there may be times when you need to reset your DSM, such as after replacing your vehicle’s battery or if the memory settings are not working properly. In this comprehensive guide, we’ll walk you through the steps to reset your DSM and restore your custom comfort settings, both manually and using an OBD scanner.

Understanding the Driver Seat Module (DSM)

The Driver Seat Module is an electronic control unit responsible for managing the memory functions of your vehicle’s power driver seat. It stores personalized settings for seat position, lumbar support, side bolsters, and in some cases, even the position of the steering wheel, mirrors, and pedals.

When you save a custom driver profile, the DSM records the current position of all these adjustable components. Then, when you recall that memory setting, the module communicates with the various motors and actuators to move each component back to its saved position.

Most vehicles with memory seats allow you to save at least two different driver profiles, often labeled as “Driver 1” and “Driver 2” or “Memory 1” and “Memory 2”. Some high-end models may offer even more customizable profiles.

Reasons to Reset Your DSM

There are a few scenarios where you might need to reset your Driver Seat Module:

Battery replacement or disconnection: If your vehicle’s battery dies or is disconnected for maintenance, it can cause the DSM to lose its stored memory settings.
Inconsistent or non-functional memory settings: If you find that your saved driver profiles are not being recalled correctly, or the memory function stops working entirely, resetting the DSM can often resolve the issue.
Selling or transferring ownership of your vehicle: If you plan to sell your car or transfer it to a new owner, it’s a good idea to reset the DSM to its factory default settings. This ensures the new owner starts with a clean slate and can program their own personalized settings.
After certain repairs or maintenance: Some repair procedures, especially those involving the electrical system or control modules, may require disconnecting the battery. In these cases, the technician should reset your DSM as part of the post-repair checklist.

Now that we’ve covered the basics of the Driver Seat Module and when you might need to reset it, let’s dive into the two main methods for performing a DSM reset: the manual procedure and using an OBD scanner.

Method 1: Manually Resetting Your DSM

For most vehicles, you can reset the Driver Seat Module without any special tools by following a specific sequence of steps. The exact procedure may vary slightly depending on your vehicle’s make and model, so it’s always a good idea to consult your owner’s manual for specific instructions. However, the general process is fairly consistent across most brands.

Here’s a step-by-step guide to manually resetting your DSM:

Sit in the driver’s seat and close all the doors. Make sure you have your key fob with you.
Adjust the seat to your desired position using the various power seat controls. This includes forward/backward position, seat height, seatback angle, lumbar support, and any other adjustable aspects of the seat. Take your time to get the positioning just right, as this will serve as your new default setting.
Adjust the mirrors and steering wheel (if equipped with power adjustment) to your preferred positions. Some vehicles also allow you to save the position of the pedals and even the radio presets to your driver profile.
Press and hold the “Set” button, usually located on the driver’s door panel near the memory seat buttons. The exact location and labeling may vary, but look for a button that says something like “Set,” “Memory,” or “Program.”
While still holding the “Set” button, press and release the memory button you want to assign your current settings to (usually labeled as “1” or “2”). You should hear a chime or see a message on the driver information display confirming that the settings have been saved.
Release the “Set” button after you’ve selected the memory position. Your personalized settings are now stored and can be recalled anytime by pressing the corresponding memory button.
Repeat the process for any additional driver profiles you want to save (if your vehicle supports more than one).

That’s it! You’ve now manually reset your DSM and programmed your custom comfort settings. The next time you get in your vehicle, simply press your assigned memory button, and the seat, mirrors, and steering wheel will automatically adjust to your saved positions.

Method 2: Resetting Your DSM with an OBD Scanner

For some vehicles, particularly newer models with more advanced electronic systems, you may need to use a specialized diagnostic tool to reset the Driver Seat Module. This method involves connecting an OBD (On-Board Diagnostics) scanner to your vehicle’s OBD-II port and using it to communicate with the DSM and other control modules.

Here’s a general overview of how to reset your DSM using an OBD scanner:

Locate your vehicle’s OBD-II port, typically found underneath the dashboard on the driver’s side. It’s a 16-pin connector that looks similar to a computer printer port.
Plug your OBD scanner into the OBD-II port. Make sure the connection is secure and the scanner is powered on.
Turn your vehicle’s ignition to the “On” position without starting the engine. This will wake up the vehicle’s electronic systems and allow the scanner to communicate with the control modules.
Navigate through the OBD scanner’s menu until you find the option for “Body Control Modules” or something similar. The exact terminology may vary depending on your specific scanner.
Select the option for the “Driver Seat Module” from the list of body control modules. If you don’t see a specific option for the DSM, look for a more general category like “Seating Modules” or “Memory Seat Functions.”
Look for an option to “Reset” or “Recalibrate” the DSM. This may be labeled as something like “Clear Memory Settings,” “Restore Default Positions,” or “Relearn Procedure.”
Follow the on-screen prompts to initiate the DSM reset process. This may involve pressing certain buttons on the scanner, turning the ignition off and on, or performing specific actions inside the vehicle (like pressing the memory seat buttons in a certain sequence).
Wait for the scanner to confirm that the reset process is complete. This may take anywhere from a few seconds to a couple of minutes, depending on your vehicle.
Disconnect the OBD scanner and turn off your vehicle’s ignition.

After resetting your DSM with an OBD scanner, you’ll need to reprogram your personalized comfort settings using the manual method described earlier (sitting in the driver’s seat, adjusting the components to your desired positions, and saving them to a memory profile).

It’s important to note that not all OBD scanners have the ability to reset the Driver Seat Module. Basic code readers used for checking engine trouble codes may not have the necessary software or functions to access body control modules. To ensure compatibility, look for a professional-grade OBD scanner that specifically lists DSM reset capabilities for your vehicle’s make and model.

Tips for Maintaining Your DSM and Memory Seat Functions

To keep your Driver Seat Module and memory seat functions working properly for years to come, follow these simple maintenance tips:

Avoid repeatedly pressing the memory buttons while the seat is already in motion. This can confuse the DSM and cause it to stop functioning correctly. Wait for the seat to finish moving before pressing any other buttons.
Be gentle with the power seat controls. Aggressive or excessive use of the adjustment switches can wear out the motors and actuators over time, leading to inconsistent or failed memory functions.
Regularly check and clean the seat tracks and mechanisms. Dirt, debris, and spilled liquids can interfere with the smooth operation of the power seat components and cause issues with the memory settings.
< strong>If you notice any unusual noises or jerky movements while the seat is adjusting, have it inspected by a qualified technician. Catching and addressing problems early can prevent more serious (and expensive) failures down the road.
Avoid using aftermarket seat covers or cushions that are not specifically designed for your vehicle. These can interfere with the seat’s sensors and motors, causing the memory functions to work incorrectly or not at all.
If you do need to disconnect your vehicle’s battery for any reason, be prepared to reset your DSM and reprogram your memory settings afterward. It’s a good idea to write down or take photos of your preferred seat, mirror, and steering wheel positions beforehand so you can easily recreate them later.

Troubleshooting Common DSM Issues

Even with proper maintenance and care, you may occasionally encounter problems with your Driver Seat Module or memory seat functions. Here are some common issues and potential solutions:

Memory settings not saving or recalling correctly: First, try resetting the DSM using one of the methods described above. If that doesn’t work, check for any obstructions or debris in the seat tracks that could be interfering with the sensors. If the problem persists, there may be a fault with the DSM itself or one of the related components (like a faulty actuator or wiring issue). In this case, it’s best to have the system diagnosed by a professional.
Seat, mirrors, or steering wheel not moving when a memory button is pressed: This could be caused by a blown fuse, a wiring problem, or a failed motor or actuator. Check your vehicle’s owner’s manual for the location of the relevant fuses and replace any that are blown. If the fuses are good, the issue is likely with one of the components or the DSM itself, which will require further diagnosis.
Seat moving to the wrong position when a memory setting is recalled: This usually indicates that the stored settings have been corrupted or overwritten. Try reprogramming the memory positions using the manual method. If the problem continues, there may be a fault with the DSM’s memory storage or software, which will need to be addressed by a qualified technician.
Unusual noises or jerky movements during seat adjustment: This could be a sign of worn-out motors, actuators, or tracks. Inspect the seat components for any visible damage or obstructions. If everything looks okay, the noise could be coming from inside one of the motors, which may need to be replaced.
Seat not responding to any controls at all: This is often caused by a loss of power to the DSM or the seat motors. Check the relevant fuses and wiring connections for any issues. If the problem is not electrical, there may be a mechanical failure (like a broken gear or linkage) that is preventing the seat from moving.

If you’re unable to resolve a DSM or memory seat issue on your own, don’t hesitate to seek the assistance of a qualified automotive technician. They have the tools, knowledge, and experience to diagnose and repair even the most complex problems with your vehicle’s electronic systems.
