What is a Honda Fit GP airbag control unit?
The Honda Fit GP 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 essential for safety.
This key component of the Supplemental Restraint System (SRS) processes signals from crash and passenger sensors. The goal is to precisely and promptly deploy airbags and seatbelt pretensioners in the event of a collision.
It also stores important crash data and vehicle-specific software information. When a replacement or repair is required, this data often needs to be reprogrammed to ensure proper function.
Why is the Honda Fit GP airbag control unit defective?
A Honda Fit GP airbag control unit can be defective because it has stored crash data after an accident that needs to be erased, or because it has internal errors. Improper programming or the installation of an unsuitable module often leads to malfunctions and warning lights.
Because the control unit irreversibly stores crash data after an accident, it often needs to be repaired or replaced. This prevents the airbag system from reactivating.
Internal electronic faults, such as those caused by aging or voltage spikes, can also cause a failure. This often manifests itself in a permanently illuminated airbag warning light.
An incorrectly programmed or incorrectly programmed replacement part will result in internal ECU errors. Therefore, a professional Honda Fit GP airbag control unit repair with subsequent coding is essential.
Common error codes for Honda Fit GP airbag control unit repair
During Honda Fit GP airbag control unit repair, specific error codes indicate problems directly related to the control unit itself. These codes signal internal defects, inconsistencies in model data, or short circuits within the ECU module.
- 85-63 → Meaning: Model ID code or variation code inconsistent → Cause: Incorrect or missing vehicle data in the control unit.
- 85-64 → Meaning: Control unit serial ID code inconsistent → Cause: Invalid serial number recognition by the control unit.
- 87-31 → Meaning: Internal error in the airbag control unit → Cause: Hardware or software defect in the ECU.
- 87-32 → Meaning: Side Impact Airbag Cutoff Indicator remains on → Cause: Problem with the control circuit for the side airbag cutoff indicator.
- 91-1x → Meaning: Internal error in the SRS control unit → Cause: Generic internal defect in the ECU electronics.
- 91-2x → Meaning: Short circuit in the SRS indicator circuit (airbag ECU) → Cause: Electrical short circuit in the control circuit of the airbag warning light.
What part numbers are available for the Honda Fit GP airbag control unit repair?
For Honda Fit GP airbag control unit repairs, two original OEM part numbers are primarily relevant: 77960-T5A-A212-M1 for 2015-2017 models and 77960-TK6-A040-M1 for 2012-2013. These must match exactly, as no universal replacement parts exist.
Part number 77960-T5A-A212-M1 is specifically designed for Honda Fit GP models from 2015 to 2017. This control unit is a certified original part that often requires programming to the vehicle's VIN after installation.
For models from 2012 to 2013, part number 77960-TK6-A040-M1 is the correct airbag control unit. This is also a genuine, tested, used part that is only suitable for vehicles that fit exactly.
It's important to note that there are no officially documented replicas or alternative OEM numbers available for the Honda Fit GP airbag control unit. A professional Honda Fit GP airbag control unit repair should only use genuine parts.
