Honda City 5th Gen Airbag Control Unit Repair

What is a Honda City 5th Gen airbag control unit?

The Honda City's 5th-generation airbag control unit is a sophisticated electronic unit that plays a central role in the vehicle's safety concept. It controls the precise and rapid deployment of the airbags in the event of a collision or critical driving situation, thus ensuring optimal occupant protection.

This unit, also called the SRS Control Module, continuously monitors signals from various impact and position sensors in the vehicle. In an emergency, it activates passive restraint systems such as airbags and seatbelt pretensioners within milliseconds.

In addition to activation, the control unit records important crash data that is crucial for diagnostic purposes after an accident. It is an integral component of vehicle safety.

Why is the Honda City 5th Gen airbag control unit defective?

The Honda City 5th Gen airbag control unit often fails due to internal component failure, crash data not being erased after an accident, or a short circuit. This causes the system to report malfunctions or the airbags to malfunction, compromising vehicle safety.

The airbag control unit often remains defective because immutable crash data is stored in the system after an impact. A special Honda City 5th Gen airbag control unit repair is then necessary to restore functionality.

Internal electronic faults, such as memory problems, or communication errors with other vehicle systems can also cause a failure. This typically manifests itself in an illuminated airbag warning light on the dashboard.

Common error codes for Honda City 5th Gen airbag control unit repair

When diagnosing a faulty Honda City 5th Gen airbag control unit, specific error codes are often read, indicating internal problems or communication errors. These codes help identify the exact cause of the failure and perform a targeted Honda City 5th Gen airbag control unit repair.

• B0001 → Internal control unit error → Indicates a problem within the SRS control unit.
• B1000 → Control unit communication error → Signals disruptions in the data transmission of the airbag module.
• 5-1 → Internal error with stored crash data → Requires an airbag module reset after an accident because the data must be deleted.
• 87-31 → Internal control unit error → Indicates a hardware malfunction of the airbag module.
• 91-1x / 91-2x → Internal error / short circuit warning light → Can indicate a defect in the control unit or the airbag warning light circuit.

What part numbers are available for the Honda City 5th Gen airbag control unit repair?

While specific OEM part numbers for the Honda City 5th Gen airbag control unit are difficult to find publicly, certain Honda/Bosch numbers are considered highly compatible for repair. Accurate matching often requires the vehicle's VIN to confirm the correct part number for your airbag module.

Among the likely compatible OEM part numbers is **77960-T0A-Q010-M4** from Honda/Bosch. This number is often cited for original airbag control units (SRS ECUs) in Honda vehicles and is relevant for the Honda City 5th Gen airbag control unit repair.
