What is a Nissan 180SX S13 airbag control unit?
The Nissan 180SX S13 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It continuously monitors sensors in the vehicle, stores important crash data, and ensures the proper functioning of all airbag modules and seatbelt pretensioners to provide maximum protection.
This safety-relevant module is essential for the active safety of the Nissan 180SX S13.
It receives signals from crash sensors and triggers airbags and seat belt tensioners in an emergency.
Why is the Nissan 180SX S13 airbag control unit defective?
The Nissan 180SX S13 airbag control unit often fails due to damage caused by aging, electrical surges, or short circuits; internal components such as capacitors or microchips can then fail. Even after an accident, even if no airbags are deployed, the module may retain crash data, necessitating repair or a reset.
Other common causes of errors include moisture damage or corrosion on the connectors.
This often leads to communication errors or system failures that require a Nissan 180SX S13 airbag control unit repair.
Error codes such as B1239 or B1414 directly signal an internal error in the control unit.
Common error codes for Nissan 180SX S13 airbag control unit repair
When diagnosing a faulty Nissan 180SX S13 airbag control unit, specific error codes will appear that indicate internal malfunctions or communication issues. These codes help with precise fault location and are crucial for a successful Nissan 180SX S13 airbag control unit repair, as they identify the cause of the failure.
- B1000 → Control unit communication error → Cause: Internal fault or connection problem.
- B1210 → Roof module airbag deployed → Cause: Airbag deployed in the roof module.
- B1211 → Roof module airbag & belt tensioner triggered → Cause: Multiple airbag and belt tensioner triggering.
- B1239 → Airbag control unit defective (reset/repair) → Cause: Internal error of the control unit.
- B1336-B1342 → Communication front door satellite sensor right → Cause: Connection problems with the sensor.
- B1414 → Airbag control unit error → Cause: General internal control unit error, often due to a defect.
- B1418 → Left front impact sensor communication → Cause: Fault in communication with the impact sensor.
- B1421 → Frontal impact detected, airbag deployed → Cause: Airbags were activated by a frontal impact.
- B1422 → Side impact detected, airbag deployed → Cause: Airbags were activated by a side impact.
- U1000 → CAN communication error → Cause: General fault in the CAN bus system.
- U1010 → Airbag control unit CAN communication error → Cause: Specific communication problem of the airbag control unit in the CAN bus.
What part numbers are available for the Nissan 180SX S13 airbag control unit repair?
Unfortunately, there are no directly and 100% verified OEM part numbers available from publicly accessible sources for the Nissan 180SX S13 airbag control unit that would allow for clear identification. The exact part number is vehicle-specific and often requires access to official Nissan parts catalogs or professional databases for precise matching during Nissan 180SX S13 airbag control unit repair.
It is strongly recommended to consult official Nissan dealers or specialized spare parts databases (e.g. TecDoc/TecAlliance) with the chassis number.
Contacting suppliers such as Autoliv or Bosch directly can also help determine the correct part number.
Without an exact OEM part number, precise ordering or repair of the module is difficult, but diagnosis of the defective control unit remains possible.
The Nissan 180SX S13 airbag control unit repair is possible despite missing publicly known part numbers through error codes and visual inspection.
