What is an Alfa Romeo 166 936 airbag control unit?
The Alfa Romeo 166 936 airbag control unit is the central safety unit in your vehicle, continuously monitoring all occupant restraint systems. In the event of an accident, it precisely activates the airbags and seatbelt pretensioners to ensure passenger safety. This module is crucial for passive safety and stores important crash data.
It is specifically designed for the Alfa Romeo 166 (model type 936) from approximately 1998 to 2007. The unit processes signals from crash sensors and is the control center for front and side airbags. This specific component should not be confused with airbag sensors or other vehicle modules.
Why is the Alfa Romeo 166 936 airbag control unit defective?
A defective Alfa Romeo 166 936 airbag control unit can have various causes, from internal errors and memory corruption to the storage of crash data after an accident. These defects can cause the entire airbag system to malfunction and require a professional Alfa Romeo 166 936 airbag control unit repair to restore safety.
These control units often irreversibly store crash data after a collision, resulting in the system locking up. Internal components can also fail, resulting in specific error codes. Voltage fluctuations or short circuits can also damage the module and cause failure.
Common error codes for Alfa Romeo 166 936 airbag control unit repair
When diagnosing a faulty Alfa Romeo 166 936 airbag control unit, specific B-codes may occur, indicating internal problems or communication errors within the module. These error codes are crucial for performing a targeted Alfa Romeo 166 936 airbag control unit repair, as they do not originate from sensors or seatbelt pretensioners.
- B1000 → Control unit communication error → Internal module problem
- B1001 → Internal memory or software error → Defect in the ECU memory
- B1010 → Power supply error in the control unit → Problem with the power supply to the module
- B1020 → Open or short circuit in the airbag control circuit → Internal wiring or components defective
- B1030 → EEPROM error or memory problem in the control unit → Permanent memory defect in the module
- B1040 → Watchdog monitoring failure in the control unit → Internal monitoring mechanism failed
- B1050 → Error in the airbag control unit firmware → Software integrity check failed
- B1100 → Internal self-test of the control unit failed → Module self-diagnosis failure
- B1200 → Communication error with other control units → CAN bus connection problem
- B1210 → Faulty calibration or initial learning values in the control unit → Basic configuration damaged
What part numbers are available for the Alfa Romeo 166 936 airbag control unit repair?

The most important and verified numbers include 60679086 and 1560480480 from Alfa Romeo, as well as 60678004 from supplier TRW, exclusively for the central airbag control unit.
Part number 60679086 is the most commonly verified original OEM number for the 936 series airbag control unit. 1560480480 often serves as an alternative OEM cross-reference number for the same part. The number 60678004 comes directly from TRW, a recognized original supplier for airbag systems. These numbers are specifically verified for the Alfa Romeo 166 Type 936 airbag control unit and are not sensors.
Functionality and advantages of an Alfa Romeo 166 936 airbag control unit repair
The Alfa Romeo 166 936 airbag control unit's functionality is based on continuously monitoring crash sensors to trigger the safety systems in the event of an impact. A professional Alfa Romeo 166 936 airbag control unit repair, rather than replacement, offers significant cost advantages and promotes component reuse by resetting crash data.
The module monitors signals from front and side airbag sensors and decides whether to fire them. It also stores relevant crash data that could cause a system blockage after an accident. A specialized reset service restores the module to full functionality after an accident, avoiding the need for a costly replacement. This is a sustainable alternative to replacing a broken control unit.
Installation position and compatibility of the Alfa Romeo 166 936 airbag control unit
The Alfa Romeo 166 936 airbag control unit is strategically located in the vehicle, usually under the driver's seat or in the center console, to protect it from damage and ensure easy access for service. It is fully compatible with all model variants of the Alfa Romeo 166 (Type 936) from 1998 to 2007, including gasoline and diesel engines.
The unit is connected to the power supply, sensors, and CAN bus via multi-pin connectors. It fits four-door sedan models with front-wheel drive and various transmission variants. Typical chassis numbers begin with ZAR936..., which confirms compatibility with the 936 series and enables repair.
