2019-2021 Honda Passport Air Bag Control Module: Programming, Recalls, and Replacement Guide
This guide covers the essential details for diagnosing, replacing, and programming the SRS unit in your 2019-2021 Honda Passport.
- Programming is mandatory for any replacement module (new or used) and requires a dealer or specialized shop.
- A persistent airbag warning light means the safety system is disabled and will not deploy in a crash.
- Never buy a used module from a vehicle where airbags deployed, as it will contain locked crash data.
- A recall for the passenger seat weight sensor (NHTSA 26V332000) can cause SRS light issues and should be checked before replacing the module.
Symptoms of a Failing Air Bag Control Module
The most common and obvious sign of a problem with the SRS system is an illuminated airbag warning light on your dashboard. This light should turn on for about six seconds when you start the vehicle for a self-check, and then turn off. If the light stays on, flashes, or never comes on at all, it indicates a fault within the system.
- Persistent SRS Warning Light: If the airbag light on the dashboard remains lit while driving, it signals a fault in the supplemental restraint system. The system is disabled and airbags will not deploy in a crash.
- No Communication with Scan Tools: In some cases of internal failure, the module may stop communicating with diagnostic scan tools, making it impossible to read fault codes.
- Fault Codes Stored: A professional scan tool can retrieve Diagnostic Trouble Codes (DTCs) from the module. While many codes point to specific sensors or airbags, some codes indicate an internal failure of the SRS unit itself. Common Honda codes for internal failure include those in the 5x-xx and 6x-xx series (e.g., 6-4 Internal Failure Of SRS Unit 🎬 Watch: How to read and clear Honda SRS codes).
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
For the 2019-2021 Honda Passport, there is a significant safety recall that owners should be aware of. While it does not directly involve the airbag control module itself, it pertains to a critical sensor that the module relies on.
NHTSA Recall 26V332000: Front Passenger Seat Weight Sensor
Honda issued a recall for certain 2019-2021 Passport models because the front passenger seat weight sensor may crack and short circuit. This can cause the passenger airbags to deploy improperly or unintentionally during a crash, increasing the risk of injury, particularly for children or smaller adults. The fix involves dealers replacing the seat weight sensors free of charge. This issue can cause the SRS warning light to illuminate.
Pro Tip: Before assuming the airbag control module has failed, it is crucial to have a Honda dealer check if your vehicle is affected by this or any other open recalls. A faulty sensor can mimic the symptoms of a bad module.
Programming and Calibration: The Most Important Step
A replacement Air Bag Control Module—whether new or used—absolutely must be programmed to your specific vehicle. This is not an optional step. The SRS unit needs to be configured with your vehicle's Vehicle Identification Number (VIN) and learn the specific sensors and components installed in your Passport. Without proper programming, the system will not function, and the airbag light will remain on.
This programming is typically performed by a Honda dealership or a well-equipped independent repair shop that has access to Honda's diagnostic software (like the HDS - Honda Diagnostic System). Do-it-yourself installation is possible for the physical part, but the final programming step requires professional tools and expertise.
Buying a Used Air Bag Control Module for Your Passport
Purchasing a used OEM module can offer significant savings over a new part from the dealer. However, there are critical factors to consider to ensure you get a safe and functional part.
Warning: Never install a module from a vehicle that has been in an accident where the airbags were deployed. The module will have "crash data" stored and will be locked. While some specialist services claim to reset these modules, the safest option is to source a part from a vehicle with no collision history.
- Verify the Part Number: The most critical step is to match the OEM part number exactly. For the 2019-2021 Honda Passport, the primary part number is 77960-TGS-A01. Using a module with a different part number can lead to incompatibility and system failure.
- Inspect for Damage: When you receive the used module, carefully inspect the case and connectors for any signs of physical damage, corrosion, or water intrusion. The module is located in the center console area, which can be susceptible to spills.
- Source from a Reputable Supplier: Buy from a seller that guarantees the part is from a non-wrecked vehicle and offers a warranty. Some used parts sellers will explicitly state if a module has stored crash data.
Replacement Overview
The SRS control unit on the 2019-2021 Honda Passport is located under the center console, toward the front. While the physical replacement is straightforward for a moderately skilled DIYer, it requires extreme caution and is followed by mandatory professional programming.
CRITICAL SAFETY WARNING: The airbag system can hold an electrical charge. Before beginning any work, you MUST disconnect the negative terminal of the 12-volt battery and wait at least 3-15 minutes for the system's capacitors to fully discharge. Failure to do so can result in accidental airbag deployment and serious injury.
- Disconnect the negative battery cable and wait at least 3 minutes.
- Access the center console. This may require removing trim panels and the console assembly itself to gain clear access to the module.
- Carefully unbolt the three T30 Torx bolts holding the module to its bracket.
- Disconnect the electrical connectors. They have locking tabs that must be depressed to be removed.
- Install the replacement module, reconnect the connectors, and reassemble the console.
- Reconnect the battery.
- Take the vehicle to a dealer or qualified shop to have the new module programmed and the SRS system initialized.

Frequently Asked Questions (FAQ)
Can I drive my Passport with the airbag light on?
No. An illuminated SRS light means the airbag system is disabled and will not deploy in a crash, compromising vehicle safety. It should be serviced as soon as possible.
Does a used airbag module need to be programmed?
Yes, absolutely. Any replacement SRS module, new or used, must be programmed to the vehicle's VIN and specific configuration by a dealer or a shop with the correct diagnostic tools. The system will not work without this step.
Why is my airbag light still on after replacing the module?
There are two likely reasons. First, the replacement module has not been programmed to your vehicle yet. Second, the fault may lie with another component in the SRS system, such as a sensor, clock spring, or wiring, and not the module itself. A full system diagnostic is required.
Can I reset my original module after an accident?
After any airbag deployment, Honda requires the SRS unit to be replaced. However, there are third-party services that specialize in clearing crash data from modules. While this is a lower-cost option, replacing the unit with a used part from a non-wrecked vehicle is often considered the safer and more reliable approach.
