What is a Maserati GranCabrio M145C airbag control unit?
The Maserati GranCabrio M145C airbag control unit is the central safety unit that activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors various crash and pressure sensors in the vehicle, stores relevant crash data, and ensures precise and rapid deployment for optimal occupant safety.
This electronic control unit (ECU) is essential for the safety system of your Maserati GranCabrio M145C and ensures reliable protection of passengers.
The control unit communicates with other vehicle systems via an integrated CAN bus network to ensure a holistic safety function.
Why is the Maserati GranCabrio M145C airbag control unit defective?
A Maserati GranCabrio M145C airbag control unit can be defective due to internal component failure, a power supply issue, or crash data stored after an accident that requires a reset. Communication problems in the CAN bus system or a general hardware error often lead to a failure that requires a Maserati GranCabrio M145C airbag control unit repair.
Common causes are internal memory errors (EEPROM errors) or power supply problems that affect functionality.
A failure can also be caused by insufficient bus communication or an error in the internal clock generator.
After a crash, the control unit stores indelible data that requires replacement or professional repair and reset.
Common error codes for Maserati GranCabrio M145C airbag control unit repair
During a Maserati GranCabrio M145C airbag control unit repair, general OBD-II body trouble codes (B-codes) are typically read, indicating internal problems with the control unit or communication disruptions. Since model-specific OEM lists are often not public, these codes serve as important indicators of a necessary repair.
- B1000 → Control unit communication error → The airbag ECU cannot communicate correctly with other systems.
- B1600 → Undervoltage in the airbag control unit → An insufficient power supply impairs the function of the control unit.
- B1606 → Internal memory error or memory leak → Problems with the internal memory of the airbag module.
- B1615 → Bus communication error (e.g. CAN bus) → Disturbances in the data flow between control units.
- B1622 → Timing or clock error in the control unit → The internal timing of the control unit is faulty.
- B1632 → EEPROM error in the control unit → A defect in the non-volatile memory of the airbag module.
- B1650 → Control unit self-test error → The control unit could not successfully complete the internal self-test.
- B1681 → Internal hardware error control unit → There is a general defect in the hardware of the airbag ECU.
What part numbers are available for the Maserati GranCabrio M145C airbag control unit repair?
There are no 100% verified, publicly available OEM part numbers for the Maserati GranCabrio M145C airbag control unit repair. This is because such safety-relevant information is often only accessible to authorized Maserati dealers or professional workshops via special databases to ensure correct and safe spare parts procurement.
A part number 250328 was found in a used spare parts catalog for "Maserati GranCabrio M145 Other Control Units / Modules", but it has not been conclusively confirmed whether this is the airbag control unit.
Although manufacturers such as Bosch, Continental, Siemens and Autoliv produce airbag control units, specific OEM numbers for the Maserati GranCabrio M145C are not explicitly listed in their public catalogs.
For precise identification of the correct part number, it is strongly recommended to consult an authorized Maserati dealer or a specialized Maserati workshop with access to TecDoc/TecAlliance or Bosch ESI[tronic] databases to ensure a successful Maserati GranCabrio M145C airbag control unit repair.
