What is a Honda CRX AS airbag control unit?
The Honda CRX AS airbag control unit, also known as the SRS control unit, is the safety-relevant heart of your vehicle's passive safety system. It continuously receives and processes signals from crash sensors to precisely and rapidly deploy the airbags and seatbelt pretensioners in the event of an impact, thus providing optimal occupant protection.
This central control unit continuously monitors all components of the airbag system, from the modules to the sensors. It stores important crash data, ensuring the correct functioning of all restraint systems in the Honda CRX AS.
A defective airbag control unit can severely compromise safety. Professional diagnosis and repair are essential to restore the full functionality of the Honda CRX AS airbag control unit.
Why is the Honda CRX AS airbag control unit defective?
A Honda CRX AS airbag control unit can fail for a variety of reasons, often due to internal electronic errors, overvoltage, an accident with airbag deployment, or simply due to aging components. In such cases, a professional repair is often the most cost-effective solution to restore safety.
After an accident involving airbag deployment, the control unit stores crash data, which prevents further use. It must then be reset or the Honda CRX AS airbag control unit repaired.
Internal component failures or software problems can also cause failure. This is often indicated by an illuminated SRS warning light in the dashboard. Early diagnosis helps prevent major problems.
Common error codes for Honda CRX AS airbag control unit repair
When diagnosing a faulty Honda CRX AS airbag control unit, specific trouble codes are read that indicate the nature of the problem. These DTCs are crucial for precisely locating the defect and successfully repairing the SRS system.
- 1-1 → Open circuited or high resistance in the driver airbag module → ECU error in the circuit
- 1-2 → High resistance in the driver airbag module → Wiring or ECU problem
- 1-3 → Short circuit to another wire or low resistance in the driver airbag module → Electrical short circuit
- 1-4 → Short circuit to positive current (12 V) in the driver airbag module → Incorrect voltage in the circuit
- 1-5 → Short circuit to ground in the driver airbag module → Ground connection problem
- 2-1 → Open circuited or high resistance in the passenger airbag module → ECU circuit error
- 2-2 → High resistance in the passenger airbag module → Wiring or ECU problem
- 2-3 → Short circuit to another wire or low resistance in the passenger airbag module → Electrical short circuit
- 2-4 → Short circuit to positive current (12 V) in the passenger airbag module → Incorrect voltage in the circuit
- 2-5 → Short circuit to ground in the passenger airbag module → Ground connection problem
- 87-31 → Internal error in the SRS/airbag control unit → Internal ECU defect
- 91-1x → Internal error in the SRS/airbag control unit → Internal ECU defect
- 91-2x → Short circuit in the SRS indicator circuit → Defect in the warning light circuit
- 85-63 → Model ID or variation code inconsistent → Faulty ECU programming
- 85-64 → ECU serial ID code inconsistent → ECU programming error
- 85-71 → OPDS (Occupant Position Detection System) not initialized → ECU initialization error
- 85-78 → OPDS not initialized → ECU initialization error
What part numbers are available for the Honda CRX AS airbag control unit repair?
Unfortunately, there are no 100% verified OEM part numbers available from publicly accessible sources for the Honda CRX AS airbag control unit, which can make identification for repairs difficult. The exact number is crucial for a successful repair.
Research revealed that common databases and catalogs do not list a specific part number for the CRX AS airbag control unit. The numbers found often referred to other control units, such as engine or ABS units, for example, 37820-PE7-732 for engine control units.
To obtain the exact part number for your Honda CRX AS airbag control unit, we recommend contacting an authorized Honda dealer directly, providing the vehicle identification number (VIN). Specialized workshops with access to TecDoc or manufacturer databases can also assist.
A repair is often possible even without a known part number if the old part is sent in. The repair service can identify the defective module directly on the module and thus perform the appropriate repair for your control unit.
