If you are unsure about how to repair, diagnose, or program the Coding Tire Pressure Control System Deactivate error, contact VCCarTool via WhatsApp: +1 (901) 414 – 1927 for assistance to avoid causing more serious errors.
1. Understanding Your Goal: TPMS Deactivation and FTM Activation
What exactly are we trying to achieve? We aim to remove the existing Tire Pressure Monitoring System (TPMS) and activate the Flat Tire Monitor (FTM) on BMW E9x platforms. This switch can be preferred for economic reasons, especially if you’re avoiding the cost of additional TPMS sensors.
TPMS vs FTM: Key Differences
What are the differences between TPMS and FTM?
| Feature | TPMS (Tire Pressure Monitoring System) | FTM (Flat Tire Monitor) |
|---|---|---|
| Functionality | Uses sensors inside each wheel to directly measure tire pressure. Transmits data to a central module (RDC) that alerts the driver to pressure drops in real-time. | Compares rotational speeds of the wheels using existing speed sensors. Detects a flat tire by identifying differences in wheel speeds. |
| Accuracy | Highly accurate, provides real-time pressure data from each tire. | Less accurate than TPMS as it only detects significant pressure loss that affects wheel speed. Doesn’t detect uniform pressure loss across all tires. |
| Cost | Higher upfront and maintenance costs due to sensor replacements. | Lower cost as it utilizes existing vehicle sensors, eliminating the need for additional hardware. |
| Sensor Requirement | Requires TPMS sensors in each wheel, which need periodic replacement. | No need for sensors. |
| Detection | Detects both individual and overall pressure drops. | Only detects flats or significant pressure loss that causes a change in wheel speed. |
| Installation | Requires physical installation of sensors and a control module. | Requires software coding to activate. |
| Year/Model | Standard in newer vehicles. | Common in older or European models as a cost-effective alternative. |
| Maintenance | Regular sensor checks and replacements. | Minimal maintenance. |
| Alert Type | Provides specific pressure readings and alerts for under or over inflation. | Alerts when a significant difference in wheel speed is detected. |
| Technology | Direct measurement via pressure sensors. | Indirect measurement by comparing wheel speeds. |
2. Essential Prerequisites for Coding
What do I need before starting?
- Laptop: A Windows laptop or a Windows virtual machine on Mac/Linux is required.
- OBDII KDCAN Cable: This cable is essential for connecting your laptop to your BMW.
- BMW Standard Tools: This suite, including NCSexpert, is necessary for coding. BimmerGeeks offers a readily available package.
- DATEN Files: These files contain the necessary data for coding your BMW.
- Functional Setup: Ensure all tools are correctly installed and functioning before proceeding. This guide does not cover the installation of NCSexpert.
3. Preparing for the Hardware Removal
Where is the TPMS RDC module located? The first physical step involves removing the TPMS RDC module. The location varies depending on your car’s build date:
RDC Module Locations
- Build Dates Up to 08/2009: Locate the RDC module inside the trunk liner, near the battery.

FAQ: Coding Tire Pressure Control System Deactivate
1. What is Coding Tire Pressure Control System Deactivate?
Coding Tire Pressure Control System Deactivate refers to the process of disabling the factory-installed Tire Pressure Monitoring System (TPMS) and, optionally, enabling the Flat Tire Monitor (FTM) on BMW vehicles, particularly the E9x series. This involves using coding software to modify the vehicle’s electronic control units (ECUs) to remove the TPMS functionality and activate the FTM feature, which uses wheel speed sensors to detect tire issues.
2. Why would someone want to deactivate TPMS and enable FTM?
There are several reasons why someone might choose to deactivate TPMS and enable FTM:
- Cost Savings: Avoiding the expense of purchasing and maintaining TPMS sensors, especially for multiple sets of wheels.
- Track Use: TPMS sensors may not be suitable for track or racing wheels.
- Preference: Some drivers prefer the simplicity of FTM over the direct pressure readings of TPMS.
3. What tools are needed for Coding Tire Pressure Control System Deactivate?
To perform Coding Tire Pressure Control System Deactivate, you will need the following tools:
- A Windows laptop (or a Windows virtual machine on a Mac/Linux system)
- An OBDII KDCAN cable to connect your laptop to the vehicle
- BMW Standard Tools software suite, including NCS Expert
- DATEN files, which contain the necessary data for coding BMW ECUs
4. Is Coding Tire Pressure Control System Deactivate legal?
The legality of deactivating TPMS varies by region. In some areas, TPMS is a mandated safety feature, and disabling it may violate local regulations. It’s essential to check your local laws before proceeding with this modification.
5. What are the risks associated with Coding Tire Pressure Control System Deactivate?
Coding the vehicle’s ECUs incorrectly can lead to various issues, including:
- Malfunctioning vehicle systems
- Error messages on the dashboard
- Potential damage to electronic components
It’s crucial to follow instructions carefully and consider seeking professional assistance to mitigate these risks. If you’re facing any difficulties, contact VCCarTool via WhatsApp: +1 (901) 414 – 1927 for assistance

7. How do I know if Coding Tire Pressure Control System Deactivate was successful?
After coding, you can verify success by:
- Checking the iDrive screen: It should display FTM (Flat Tire Monitor) instead of TPMS (Tire Pressure Monitoring System).
- Ensuring no TPMS-related error messages appear on the dashboard.
- Resetting and initializing the FTM system to confirm it functions correctly.
8. What is the difference between TPMS and FTM?
TPMS (Tire Pressure Monitoring System) uses sensors inside each tire to directly measure tire pressure and alert the driver to pressure drops. FTM (Flat Tire Monitor) uses wheel speed sensors to detect differences in rotational speed, indicating a potential flat tire. TPMS provides more accurate and real-time pressure data, while FTM is a simpler, less costly system that relies on existing vehicle sensors.
