Vehicle Damage Warnings
SRS Precautions and Procedures
General Precautions
NOTE: Some systems store data in memory that is lost when the battery is disconnected. Before disconnecting the battery, refer to Battery Terminal Disconnection and Reconnection. Procedures
Please read the following precautions carefully before performing the airbag system service. If the instructions described in this data, or the airbags could accidentally deploy and cause damage or injuries.
- Except when performing electrical inspections that requires battery power, always turn the ignition switch to LOCK (0), disconnect the negative cable from the battery, then wait at least 3 minutes before starting work.
NOTE: The SRS memory is not cleared even if the ignition switch is turned to LOCK (0) or the battery cables are disconnected from the battery.
- Use replacement parts which are manufactured to the same standards and quality as the original parts. Do not install used SRS parts. Use only new parts when making SRS repairs.
- Carefully inspect any SRS part before you install it.
Do not install any part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation.
- Before disconnecting the SRS unit connectors, always disconnect the appropriate SRS parts connectors.
- Use only a digital multimeter to check the system. If it is not a Honda multimeter, make sure its output is 10 mA (0.01 A) or less when switched to the lowest value in the ohmmeter range. A tester with a higher output could cause accidental deployment and possible injury.
- Do not put objects on the front passenger's airbag.
Steering-related Precautions
Cable Reel Alignment
- Misalignment of the cable reel could cause an open in the wiring, making the SRS system, remote steering wheel controls, or the horn inoperative. Center the cable reel whenever you do the following. Service and Repair
- Installation of the steering wheel
- Installation of the cable reel
- Installation of the steering column
- Other steering-related adjustment or installation
- Do not disassemble the cable reel.
- Do not apply grease to the cable reel.
- If the cable reel shows any signs of damage, replace it with a new one. For example, if the cable reel does not rotate smoothly, replace it.
Airbag Handling and Storage
Do not disassemble an airbag. It has no serviceable parts. Once an airbag has been deployed, it cannot be repaired or reused.
For temporary storage of an airbag during service, observe the following precautions.
- Store the removed airbag with the pad surface up. Never put anything on the airbag.
- To prevent damage to the airbag, keep it away from any oil, grease, detergent, or water.
- Store the removed airbag on a secure, flat surface away from any high heat source (exceeding 200 °F/93 °C).
- Never perform electrical inspections to the airbags, such as measuring resistance.
- Do not position yourself in front of the airbag during removal, inspection, or replacement.
- For proper disposal of a damaged airbag, refer to airbag disposal. Procedures
- The side curtain airbag module assembly is a long, jointed part containing an inflator (A), a flexible bag (B), and brackets (C). When removing or installing the side curtain airbag assembly, never:
- Handle the flexible bag.
- Drop airbag assembly.
- Cut, tear, or unwrap the tape strips.
SRS Unit, Front and Side Impact Sensors, Driver's Seat Position Sensor, Front Passenger's Weight Sensors, and Rear Safing Sensor
NOTE: Some systems store data in memory that is lost when the battery is disconnected. Before disconnecting the battery, refer to Battery Terminal Disconnection and Reconnection. Procedures
- Turn the ignition switch to LOCK (0), disconnect the negative cable from the battery then wait at least 3 minutes before starting installation or replacement of the SRS unit, or disconnecting the connectors from the SRS unit.
- Be careful not to the bump or impact the SRS unit, the front impact sensors, the side impact sensors, or the rear safing sensor whenever the ignition switch is in ON (II), or for at least 3 minutes after the ignition switch is turned to LOCK (0).
- During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the SRS unit, front impact sensors, the side impact sensors, or rear safing sensor. The airbags could accidentally deploy and cause damage or injury.
- After a collision where a front airbags, the side airbags or the seat belt tensioners, the seat belt buckle tensioners deploy, go to Component Replacement/Inspection After Deployment. Service and Repair After a collision where the airbags or the side airbags do not deploy, inspect for any damage or any deformation on the SRS unit, the front impact sensors, the side impact sensors, and the rear safing sensor Also, do the front seat active head restraint inspection. Testing and Inspection If there is any damage, replace the SRS unit and/or the sensors.
- Do not disassemble the SRS unit, front impact sensors, side impact sensors, driver's seat position sensor, front passenger's weight sensors, or rear safing sensor.
- Always install the SRS unit, driver's seat position sensor, all impact sensors, and the rear safing sensor securely with new TORX bolts torqued to 9.8 N-m (1.0 kgf-m, 7.2 lbf-ft).
- Do not spill water or oil on the SRS unit or the any of the sensors.
Wiring Precautions
Some of the SRS wiring can be identified by a special yellow outer covering, and the SRS connectors can be identified by their yellow color. Observe the following instructions:
- Never attempt to modify, splice, or repair SRS wiring.
If there is an open or damage to the SRS wiring, replace the harness.
- Be sure to install the harness wires so they do not get pinched or interfere with other parts.
- Make sure all SRS ground locations are clean, and grounds are securely fastened for optimum metal-to-metal contact. Poor grounds can cause intermittent problems that are difficult to diagnose.
- Do not use any silicone based cleaners or lubricants on any SRS connectors or terminals.
Precautions for Electrical Inspections
Special Tools Required
- Back probe adapter, 17 mm 07TAZ-001020A
- Make sure the battery is fully changed when doing electrical test. If the battery is not fully charged, the results of the tests may not be accurate.
- When using electrical test equipment, insert the probe of the tester into the wire side of the connector. Do not insert the probe of the tester into the terminal side of the connector, and do not tamper with the connector.
- Use the back probe adapter, 17 mm (07TAZ-001020A). Do not insert the probe forcibly.
- Use specified service connectors in troubleshooting.
Using improper tools could cause a diagnostic error due to poor metal-to-metal contact.
Spring-loaded Lock Connector
Some SRS connectors have a spring-loaded lock.

Opening the SRS Unit Shorting Connectors for Diagnosis
Special Tools Required
- SRS short canceller 070AZ-SAA0100
NOTE:
- To prevent damage to of the connector cavity, insert the short canceller straight into the cavity from the terminal side.
- Before installing an SRS short canceller, wash it with electric contact cleaner, then dry it with compressed air.
- Do not use an SRS short canceller if it is damaged.
- Make sure to remove the short canceller before reconnecting the SRS unit connector.
- Some systems store data in memory that is lost when the battery is disconnected. Before disconnecting the battery, refer to Battery Terminal Disconnection and Reconnection. Procedures
When SRS unit connectors A (28P) and B (28P) are disconnected, a short circuit is automatically created in the connector to prevent accidental deployment of an airbag or tensioner. The circuit may need to be opened sometimes when testing the system. Insert an SRS short canceller (070AZ-SAA0100) in the specified cavities when is necessary to keep the circuit open for testing.
Terminal numbers are shown from the wire side of the female terminals. Insert the SRS short canceller(s) into the cavities on the terminal side of the connector.
Seats with Side Airbags
Seats with side airbags have a "SIDE AIRBAG" label on the seat-back.
- Clean the seats with a damp cloth. Do not soak the seats with liquid, and do not spray steam on the seats.
- Do not repair a torn or frayed seat-back cover. Replace the seat-back cover if it is damaged.
- After a collision where the side airbag was deployed, replace the side airbag and the seat frame with new parts. If the seat-back cushion is split, it must be replaced. Refer to Component Replacement/Inspection After Deployment. Service and Repair
