What does the airbag control unit 77960-TWB-H240-M4 do?
The airbag control unit 77960-TWB-H240-M4 controls the restraint system of Honda and, in an emergency, makes the decision which airbags and seatbelt pretensioners are triggered. To do this, it reads the crash sensors and checks the overall system continuously. After an accident it stores crash data and locks itself.
If it detects a fault, it records it and shows it via the airbag warning light.
Why does the control unit 77960-TWB-H240-M4 fail?
The most common cause is crash data from an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Airbag24 erases it during the repair. In addition come aging of components, moisture and voltage spikes.
The other causes can be summarised as follows:
- Aging of electronic components
- Cold solder joints
- Moisture and corrosion at plugs
- Voltage spikes from a weak battery or a jump start
How can you tell that the 77960-TWB-H240-M4 is defective?
The airbag warning light in the instrument cluster indicates the defect when it stays on permanently or intermittently. A fault message in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared are added.
As long as the fault persists, airbags and seatbelt pretensioners may not be able to deploy in an emergency. A prompt check is therefore advisable.
