Understanding UNI-V IDD TPMS Requirements
The UNI-V IDD is a plug-in hybrid sedan that shares its TPMS platform with GM global architectures. Most UNI-V IDD models built from 2022 onward use 315MHz TPMS sensors with a specific protocol that matches OE parts like 12768826, 13516164, and 13540604. Unlike older systems that used 433MHz, this 315MHz band is common on Chinese-market GM-based vehicles.
The key challenge: UNI-V IDD sensors are programmable—they need to be cloned or programmed to match your vehicle’s existing sensor IDs. You cannot simply install any 315MHz sensor and expect it to work.
What to Check Before Ordering a TPMS Sensor for UNI-V IDD
1. Confirm the Frequency
UNI-V IDD uses 314.9–315MHz. Do not order 433MHz sensors (common on European or Japanese cars). Check your original sensor’s label—it should clearly state “315MHz” or “314.9MHz.”
2. Verify OE Number Compatibility
The BL-ST-072 | BH-Sens 314.9, 315MHz TPMS Tire Pressure Sensor | Fits Brilliance, Buick, Cadillac, Chevrolet, Gmc & 3 More | OE# 12768826, 13516164, 13540604 covers these OE numbers:
- 12768826, 13516164, 13540604, 13544443, 13581558
- 13586335, 13589597, 13598771, 13598772
- 15254101, 15268606, 15921013, 20922900
If your UNI-V IDD’s original sensor has any of these numbers stamped on it, the BL-ST-072 is a direct replacement. If not, you may need a different programmable sensor or a cloning tool.
3. Check the Sensor Type: OEM vs. Programmable
| Feature | OEM Sensor | Programmable (BL-ST-072) |
|---|---|---|
| Cost per unit | Higher ($25–45) | Lower ($12–20) |
| Fitment | Vehicle-specific | Multi-vehicle via programming |
| Installation | Plug-and-play | Requires programming tool |
| B2B advantage | Limited SKU coverage | One SKU covers 10+ OE numbers |
For UNI-V IDD owners, a programmable sensor like the BL-ST-072 is the smarter choice—it matches the OE specs exactly but costs less and reduces the risk of ordering the wrong part.
4. Know Your Relearn Procedure
UNI-V IDD uses one of two relearn methods:
- Auto-relearn: Drive above 25 mph for 10–15 minutes after sensor replacement.
- Manual relearn: Requires a TPMS activation tool (EL-50448 or equivalent) to trigger each sensor in sequence.
Check your owner’s manual or consult a local tire shop. If you don’t have a relearn tool, budget for one (typically $30–60) or plan to visit a shop.
B2B Bulk Buying Notes for UNI-V IDD TPMS Sensors
If you’re sourcing sensors for a fleet of UNI-V IDD vehicles or as a workshop buyer, these points matter:
Why One SKU Covers Many Vehicles
The BL-ST-072 works not only for UNI-V IDD but also for Brilliance, Buick, Cadillac, Chevrolet, GMC, and three other brands. This reduces your inventory from 10+ different SKUs to one programmable option. For bulk orders (50+ units), this simplifies stocking and avoids dead stock when vehicle models change.
What B2B Buyers Must Confirm
- Programming capability: Do you have a TPMS programming tool (e.g., Autel, Bartec, ATEQ)? If not, you’ll need to add one to your order.
- Frequency consistency: All BL-ST-072 units are 314.9–315MHz. Confirm your fleet’s vehicles all use this band—some older GM-based imports still use 433MHz.
- OEM number overlap: The 13 OE numbers covered by this sensor include popular GM part numbers. Cross-check your vehicle VINs against this list before ordering.
- Bulk pricing tiers: For quantities over 100 units, request pricing that includes programming clips or activation tools as add-ons.
Sample Bulk Fitment Table for UNI-V IDD Fleet
| Vehicle Model Year | OE Number | Sensor SKU | Notes |
|---|---|---|---|
| UNI-V IDD 2022–2024 | 12768826 | BL-ST-072 | Direct fit, requires programming |
| UNI-V IDD 2023–2024 | 13516164 | BL-ST-072 | Same as above |
| UNI-V IDD 2024 (late) | 13540604 | BL-ST-072 | Check relearn type |
Installation Tips for UNI-V IDD
Removing the Old Sensor
- Use a standard tire dismount machine. The UNI-V IDD uses aluminum TPMS nuts that can corrode—apply penetrating oil if stuck.
- Note the sensor position (front left, front right, etc.) before removal to simplify programming.
Programming the BL-ST-072
- Use a TPMS programming tool (e.g., Autel MaxiTPMS, Bartec Tech400Pro).
- Enter the original sensor’s ID (found on the old sensor label or via a scan tool).
- Program the new sensor with that exact ID—this avoids a full relearn on the vehicle.
- If you cannot read the old ID, install the new sensor and perform a vehicle relearn.
Relearn Procedure for UNI-V IDD
Most UNI-V IDD models support OBD relearn (via a professional scanner) or the drive-away method. If you have two sensors to replace, always replace them in pairs (same axle) to keep tire pressure readings consistent.

FAQ
Can I use a 433MHz TPMS sensor on my UNI-V IDD?
No. UNI-V IDD requires 314.9–315MHz sensors. A 433MHz sensor will not communicate with your vehicle’s TPMS receiver module. Installing one will cause the tire pressure warning light to stay on permanently.
Do I need to replace all four sensors at once?
Not necessarily. If only one sensor is faulty, replace just that one. But if your UNI-V IDD is 3+ years old, replacing all four at once saves labor costs and ensures even battery life across all sensors.
How do I know if the BL-ST-072 fits my specific UNI-V IDD year?
Check the OE number on your original sensor. If it matches any of the 13 numbers listed (12768826, 13516164, 13540604, etc.), the BL-ST-072 fits. If the number isn’t listed, contact the seller with your VIN and original sensor photo for confirmation.
Can a tire shop program the BL-ST-072 sensor?
Yes—most tire shops with modern TPMS tools (Autel, Bartec, ATEQ) can program these sensors. Ask specifically if they can clone the original sensor ID. If they cannot, you may need to purchase a programming tool or choose a pre-programmed sensor option.
