What is a Honda Passport YS airbag control unit?
The Honda Passport YS airbag control unit is the central safety unit that precisely activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors impact, seat, and belt sensors, stores relevant crash data, and ensures the proper functioning of all connected airbag modules in the vehicle at all times for maximum occupant safety.
This critical component of the Supplemental Restraint System (SRS) is essential for protecting vehicle occupants. It receives signals from various sensors in the vehicle.
Based on this data, it decides whether to deploy the front, side, and curtain airbags, as well as the seat belt pretensioners. The control unit is permanently mounted in the vehicle, usually in the protected area of the center tunnel.
Why is the Honda Passport YS airbag control unit defective?
A Honda Passport YS airbag control unit often becomes faulty if crash data was stored after an accident that requires a reset, or if it has internal errors due to aging, power surges, or moisture damage. It may also appear faulty if connected sensors are sending erroneous signals or if reprogramming is necessary after service, causing the airbag warning light to remain active.
After an accident in which the airbags are deployed, the control unit stores indelible crash data. This data prevents the system from functioning again until the module is professionally reset.
Without such a reset, the airbag warning light will remain permanently active. Internal errors such as faulty circuits or software problems can also lead to failure.
Such problems often manifest themselves as an illuminated SRS warning light for no apparent reason. Power supply issues or corrosion at the connectors can also render the module inoperable.
Common error codes for Honda Passport YS airbag control unit repair
During Honda Passport YS airbag control module repair, common Honda SRS trouble codes often occur. These codes indicate internal communication issues with the control module or its sensors. These codes are critical for diagnosis and indicate that the module may need to be reset, repaired, or reprogrammed to restore full functionality of the safety system and clear the warning light.
- B1000 → Control unit communication error → Error in the internal communication of the airbag ECU or the vehicle network.
- 87-31 → Internal errors of the SRS control unit → Hardware or software problems within the airbag module itself.
- 91-1x → Internal errors of the SRS control unit → Specific internal system malfunctions that require further diagnosis.
What part numbers are available for the Honda Passport YS airbag control unit repair?
For Honda Passport YS airbag control unit repairs, only specific Honda original part numbers are relevant, as replacement modules must be an exact match to ensure compatibility and functionality. An incorrect part number or non-original modules will result in incompatibility, persistent warning lights, and potential safety hazards, so a VIN check is essential before every order.
Compatibility of a replacement module is of utmost importance. Only a control unit with the exact same OEM part number as the original module will ensure proper function in the Honda Passport.
There are no verifiable alternative supplier numbers (such as Bosch or Continental) directly for this specific model. The modules must also be VIN-coded and programmed for the specific vehicle.
If a module is not perfectly aligned, the airbag warning light will remain active and the system will not function properly.
The main validated OEM part numbers for the airbag control unit of the Honda Passport (model years 2019-2023) are:
- 77960-TGSA-A010M2 : Commonly found and confirmed for the 2019 Honda Passport.
- 77960-TG5-A010M2 : Another common original part number for this model.
- 77960-TG5-J010M2 : Also a common OEM reference number, often listed in dealer catalogs.
- 77960-T6A-J010M2 : Listed as an OEM airbag control module for model years 2019-2023.
Before ordering or repairing the Honda Passport YS airbag control unit, it is crucial to verify the original part number on the vehicle. This is the only way to ensure the correct module is used for a successful repair and the airbag system is fully functional again.
