What is a Honda Integra 1st Gen airbag control unit?
The Honda Integra 1st Gen 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, which is critical for the vehicle's passive safety.
This electronic control unit is specifically designed to monitor and control the airbag system and seat belt pretensioners in real time. It receives and processes signals from various sensors in the vehicle.
These include front and side impact sensors, seat occupancy sensors, seat belt buckle sensors, the driver's seat position sensor, and a rollover sensor. Precise coordination of these signals is crucial for the quick and correct deployment of the airbags.
Why is the Honda Integra 1st Gen airbag control unit defective?
A Honda Integra 1st Gen airbag control unit can fail because it stores crash data after an accident, requiring a reset, or due to internal electronic errors that impair functionality. Aging, overvoltage, or moisture can also cause failures, activating the SRS warning light and necessitating a Honda Integra 1st Gen airbag control unit repair.
Common causes of a defect include stored crash data that prevents further use of the control unit after an accident. This data must be deleted by a special reset service so that the system is fully functional again.
Internal malfunctions, such as those indicated by error codes 87-31 or 91-1x, indicate defects in the internal logic or hardware of the control unit. These can be caused by aging components, poor solder joints, or unexpected voltage fluctuations.
Model ID or ECU serial ID inconsistency issues (error codes 85-63, 85-64) may indicate incorrect programming or replacement with an incompatible control unit. A power failure to the SRS, often signaled by code 9-2, will also disable the system.
Common error codes for Honda Integra 1st Gen airbag control unit repair
During Honda Integra 1st Gen airbag control unit repairs, specific error codes often occur that indicate internal system malfunctions or stored crash data. These codes, such as 9-1 or 87-31, are crucial for accurate diagnosis and identifying the repair or replacement needs of the control unit itself, enabling a successful Honda Integra 1st Gen airbag control unit repair.
- 1-1 / 1-2 → Open circuit or high resistance in the driver airbag inflator → This indicates problems in the wiring or the control unit itself.
- 85-63 → Model ID code or variation code inconsistent → This code signals faulty or inconsistent programming of the control unit.
- 85-64 → ECU Serial ID Code Inconsistent → A discrepancy in the ECU serial number may indicate an incorrect replacement or faulty configuration.
- 87-31 → SRS Unit Internal Error → This code indicates a hardware or logical defect within the airbag control unit that requires repair.
- 91-1x → SRS Unit Internal Error → Similar to 87-31, this indicates various internal control unit errors that require diagnosis and repair.
- 9-1 → SRS unit internal error with stored crash data → This critical error code means that the control unit has registered an accident and requires a reset or replacement for the Honda Integra 1st Gen airbag control unit repair.
- 9-2 → SRS power supply unit internal error → A problem with the power supply to the airbag control unit may affect the operation of the entire SRS system.
What part numbers are available for the Honda Integra 1st Gen airbag control unit repair?
After extensive research, no 100% verified and exact OEM part numbers for the Honda Integra 1st Gen airbag control unit (ECU) repair are available. The search primarily yields numbers for airbag modules, which makes sourcing the exact control unit complex and often requires a direct inquiry to Honda or specialized service providers for a successful Honda Integra 1st Gen airbag control unit repair.
Previous research in dealer catalogs and professional spare parts databases has failed to confirm any specific OEM part numbers for the airbag control unit of the Honda Integra 1st Gen (DC2). This makes directly sourcing a new or used control unit significantly more difficult.
The part numbers found, such as 06770-ST7-A80ZB or 06770-ST7-305ZB, refer exclusively to complete airbag modules (driver airbag assemblies) and not to the separate control unit. Reproduction dash trays for airbags are also not OEM control units.
Therefore, for precise identification of the airbag control unit, it is advisable to contact Honda directly or access official Honda workshop documentation. Alternatively, specialized airbag control unit repair shops often offer a service where the defective control unit can be identified and repaired using the vehicle identification number (VIN) or by reading the unit's serial number.
