The DBS — Aston Martin DBS — uses direct TPMS sensors mounted in the valve stem. Once a sensor battery dies or a wheel is rotated, the module still communicates with the sensors but no longer knows which corner is which. That is why you get a low-pressure warning or “Tire Pressure System Fault” on the dash. The fix is a relearn.
How DBS Relearn Works
There are three relearn paths, and not every DBS model year supports all three. Use a diagnostic scan tool to identify the TPMS system version before starting.
| Relearn Type | Tool Needed | Typical DBS Application | Best For |
|---|---|---|---|
| OBD relearn | OBD scanner with TPMS function | Most 2010+ models | Full replacement of all sensors |
| Stationary relearn | TPMS trigger tool (Autel, Bartec, ATEQ) | Models with trigger-based enrollment | Single-sensor replacement |
| Auto relearn | None | Certain later model years | After tire rotation only |
Auto Relearn Procedure
Some DBS TPMS modules re-learn automatically when the car is driven at speed for a set period — usually 10–20 minutes above 50 km/h (30 mph). To attempt an auto relearn, inflate all tires to the correct cold pressure, then drive a steady route without stopping. If the dash warning clears, the system recognized the sensors on its own. If not, move to an OBD or stationary relearn.
OBD Relearn Procedure
- Connect a TPMS scan tool to the DBS OBD-II port.
- Select DBS and confirm the model year when prompted.
- Choose “Relearn” or “Write IDs” in the TPMS menu.
- The scanner reads the existing sensor IDs from the module, or you enter new IDs manually from the sensor labels.
- Follow the on-screen prompts to program all four positions — front-left, front-right, rear-right, rear-left.
- Clear the DTCs and test-drive briefly to confirm the warning is gone.
OBD relearn is the fastest method and does not require removing wheels or triggering sensors individually.
Stationary Relearn Procedure
For DBS models without OBD write capability, you need a TPMS trigger tool.
- Set the tool to “Stationary Relearn” / “Set Position.”
- Start with the left-front tire. Hold the trigger tool against the tire sidewall near the valve stem and press the button.
- Wait for the horn to chirp or a confirmation on the cluster.
- Repeat in this order: left-front → right-front → right-rear → left-rear. Some models use different order — check your manual.
- Once the fourth position is learned, the system exits relearn mode automatically.
Tools You Need
At minimum: a digital tire pressure gauge and an air compressor. For OBD relearn, buy or borrow a bidirectional TPMS tool — the Autel TS508 or ATEQ VT56 work well on DBS. For stationary relearn, a compact trigger tool like the Autel MaxiTPMS TS408 is enough.
When replacing a dead sensor, do not mix frequencies. This DBS needs 315MHz units; using a 433MHz sensor will result in no signal. A direct replacement is RDE022V21 | BH-Sens 315MHz TPMS Tire Pressure Sensor | Fits Aston Martin, Audi, BMW, Bentley, Ferrari & 5 More | OE# 249363, 290569, 4F0907275A, a BH-Sens clamp-in sensor compatible with the DBS and other premium brands.
Recommended Part
If one of your DBS sensors is failing, do not replace a single unit with a different brand — sensor responses and battery life vary. Use RDE022V21 | BH-Sens 315MHz TPMS Tire Pressure Sensor | Fits Aston Martin, Audi, BMW, Bentley, Ferrari & 5 More | OE# 249363, 290569, 4F0907275A to keep all four corners identical and avoid erratic readings. After installation, run the correct relearn procedure above.
FAQ
Why is my DBS still showing a TPMS warning after driving?
The auto relearn likely did not complete or your DBS uses a trigger-based system. Perform an OBD relearn with a scanner, or a stationary relearn with a trigger tool.
Do I need to remove the wheel to relearn the DBS sensors?
No. Stationary relearn works through the tire sidewall, and OBD relearn does not require any wheel removal. Only a tire dismount is needed when replacing the sensor itself.
How often should DBS TPMS sensors be relearned?
After tire rotation, after installing new sensors, or whenever the warning appears for a position mismatch. Sensor batteries typically last 5–7 years; after that, replacement is recommended.
Can I install a used TPMS sensor on my DBS?
Only if it is 315MHz and the module accepts the existing ID. But for reliability, install a new sensor — used sensors carry unknown battery life and may fail again within months.
