Honda Jazz GD airbag control unit repair

What is a Honda Jazz GD airbag control unit?

The Honda Jazz GD airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle.

This microcontroller-based module is crucial for the passive safety of the Honda Jazz GD. It controls the deployment of the driver, passenger, and side airbags, as well as the seat belt pretensioners.

The control unit, also known as the SRS unit, processes signals from various crash sensors. It makes time-critical decisions about the necessary deployment of protective measures in the vehicle.

Why is the Honda Jazz GD airbag control unit defective?

The Honda Jazz GD airbag control unit often fails because it stores irretrievable crash data after an accident or has internal electronic errors. These problems cause the airbag warning light to stay permanently illuminated, and the system can no longer properly fulfill its protective function.

A failure can also be caused by aging components or voltage fluctuations in the vehicle electrical system.

After a collision, stored crash data is a common reason for a Honda Jazz GD airbag control unit repair. The airbag warning light then signals a malfunction in the system that requires diagnosis.

Common error codes for Honda Jazz GD airbag control unit repair

During a Honda Jazz GD airbag control unit repair, typical error codes such as '12-01' or 'Crash data stored' are displayed, indicating internal defects or triggered systems. These codes are crucial for precise diagnosis and targeted repair of problems in the airbag system.

• 12-01: Passenger airbag inflator open circuit or high resistance – A problem in the passenger airbag circuit, often in the control module itself or the wiring.
• 12-1: Right side airbag fault – Indicates a fault with the right side airbag or its associated circuit, often caused by the control unit.
• 921689: Right Side Airbag Inflator Error – This code indicates a malfunction of the right side airbag inflator, which is often traced back to the airbag control module.
• Crash data stored: Error memory cannot be erased after an accident – ​​After an impact, the control unit stores irreversible crash data that requires repair or replacement of the module.

These error codes are specific to the airbag control unit of the Honda Jazz GD and facilitate diagnosis in the workshop.

Other general errors such as seat occupancy mat or belt tensioner errors are explicitly excluded because they do not originate directly from the control unit.

What part numbers are available for the Honda Jazz GD airbag control unit repair?

For the Honda Jazz GD airbag control unit repair, two part numbers are primarily relevant: the original Honda part number 77960-SAA-E812-M1 and the corresponding Siemens supplier part number 5WK43461. These are the only 100% verified OEM numbers for this specific model and ensure full compatibility.

The Honda part number 77960-SAA-E812-M1 is the official OEM designation for the airbag control unit of the Honda Jazz GD.

Siemens is listed as an OEM supplier with the number 5WK43461, which is also suitable for this model of the Honda Jazz GD.

Other manufacturers such as Bosch, Continental or Autoliv do not offer validated replacement OEM part numbers for this specific control unit.

It is important to pay attention to the exact part number when repairing an airbag control unit to ensure the full functionality of the safety system.

Unverified numbers from classified ads or for other control units of the Honda Jazz GD are excluded.

Compatibility for models from approximately 2002 to 2008 is ensured with these part numbers for the Honda Jazz GD.
