What is a Porsche 911 Targa 992 airbag control unit?
The Porsche 911 Targa 992 airbag control unit is your vehicle's central safety unit, precisely and instantly activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of a collision. It continuously monitors sensor data and stores important crash information, thus ensuring maximum occupant safety in your Porsche.
This sophisticated electronic system is central to the control and monitoring of all airbag and seatbelt pretensioner functions in the Porsche 911 Targa 992. It continuously processes data from the crash sensors to react immediately if necessary.
The control unit also stores accident events and ensures vehicle safety in the event of a collision. It is a compact, robust unit typically installed in the center tunnel.
Power is supplied via the conventional 12V vehicle electrical system. Communication with other systems is secure via the vehicle's internal CAN bus.
This control unit is primarily designed for the Porsche 911 992 model series, built from 2019 to the present. It is compatible with various 992 variants, including the Carrera 4 S and Targa, and is therefore relevant for Porsche 911 Targa 992 airbag control unit repair.
Why is the Porsche 911 Targa 992 airbag control unit defective?
The Porsche 911 Targa 992 airbag control unit often fails because it stores crash data after an accident or fails due to internal electronic errors such as short circuits or memory defects. A faulty power supply or communication problems within the vehicle can also make a Porsche 911 Targa 992 airbag control unit repair necessary.
Internal errors in the control unit, such as B004D or B0050, are common causes of failure. A short circuit in the system, such as error code B0240, can also render the device unusable.
Memory errors in the control unit (B0260) can impair proper function. After an accident, crash data is also stored in the memory, requiring the unit to be reset.
A communication error (B1000) or a power supply error (B1001) directly indicate problems with the control unit itself. These errors block the release of the safety systems.
If the airbags are deployed or one of the above-mentioned error codes occurs, the airbag warning light will illuminate. The control unit will remain locked until the Porsche 911 Targa 992 airbag control unit is professionally repaired.
Common error codes for Porsche 911 Targa 992 airbag control unit repair
During a Porsche 911 Targa 992 airbag control unit repair, specific B-codes may occur that indicate problems directly with the control unit. Typical errors include communication problems (B1000), internal defects (B004D, B0050), short circuits (B0240), or memory errors (B0260), which impair the function of the safety systems.
- B1000 → Control unit communication error → Signal connection to the vehicle interrupted or faulty.
- B004D → Internal error in the airbag control unit → Software or hardware defect in the control unit.
- B0050 → Internal error in the airbag control unit → Further internal defect that limits functionality.
- B0240 → Short circuit in the control unit → Electrical error in the internal circuit.
- B0260 → Memory error in the control unit → Problems reading/writing data, e.g. crash data.
- B1001 → Control unit power supply error → Insufficient or interrupted power supply to the module.
These codes are manufacturer-specific B-codes that directly affect the airbag control unit of the Porsche 911 (992). They explicitly rule out errors in sensors, belt tensioners, or seat occupancy sensors.
After an accident, the control unit's error log, especially any stored crash data, must be professionally erased. This is an important step in the Porsche 911 Targa 992 airbag control unit repair.
Porsche-specific diagnostic tools such as the Piwis Tester or Bosch ESI[tronic] are essential for the detailed reading and interpretation of these codes. This ensures precise troubleshooting.
What part numbers are available for the Porsche 911 Targa 992 airbag control unit repair?
For the Porsche 911 Targa 992 airbag control unit repair, the verified OEM part number 992959655D is primarily relevant. This number, sometimes written as 992.959.655.D, is the only proven original part number for the airbag control unit of the Porsche 911 Targa 992. Other numbers refer to different Porsche models or components.
The exact and verified original Porsche OEM part number for the airbag control unit of the Porsche 911 Targa 992 is 992959655D.
An alternative spelling of this part number is 992.959.655.D. Both designations refer to the same original control unit.
This part number has been validated multiple times through trusted sources such as rareporscheparts.co.uk and TecDoc-like databases.
It is important to note that other Porsche part numbers, such as 997.618.217.08 or 964.618.217.03, apply to older 911 series and not to the 992 Targa.
Airbags or airbag modules with numbers like 992880204A/B are not control units, but rather the airbag units themselves. They are therefore not relevant when searching for a control unit.
Replacement or alternative OEM numbers from suppliers such as Bosch or Continental are not listed with their own numbers for this specific 992 Targa control unit. The original Porsche number is the key for the Porsche 911 Targa 992 airbag control unit repair.
