Vehicle Damage Warnings
SRS Precautions and Procedures
General Precautions
NOTE: Some systems store date 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 are not properly followed, the airbags could accidentally deploy and cause damage or injuries.
- Except when performing electrical inspections that require battery power, always turn the ignition switch to LOCK (0), ground the SCS line with the HDS to take the ECM/PCM out of active status, disconnect the negative cable from the battery, and wait at least 3 minutes before beginning work.
NOTE: The SRS memory is not erased 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 removing any of the SRS parts (including the disconnection of the connectors), always disconnect the SRS connector.
- 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.
- The original audio system has a coded theft protection circuit. Make sure you have the anti-theft codes for the audio system.
- Before returning the vehicle to the customer, enter the anti-theft codes for the audio system. Set the clock.
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, '07-08 models, Service and Repair '09 model, Service and Repair whenever the following is performed:
- 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 assembly is a long, jointed part containing an inflator (A), a flexible bag (B), and an adapter pipe (C). When removing or installing the side curtain airbag inflator assembly, never:
- Handle the flexible bag.
- Drop the airbag assembly.
- Cut, tear, or unwrap the tape strips.
- When installing the side curtain airbag rear tether straps (A), make sure the straps are not twisted, and there are no tubes, hoses, or harnesses routed over the straps. Otherwise, the airbag may not deploy properly.
SRS Unit, Front and Side Impact Sensors, Driver's Seat Position Sensor, Front Passenger's Weight Sensors, Roll Rate Sensor, and Rear Safing Sensor
NOTE: Some systems store date in memory that is lost when the battery is disconnected. Before disconnecting the battery, refer to Battery Terminal Disconnection and Reconnection. Procedures
- Be careful not to bump or impact the SRS unit, the front impact sensors, the side impact sensors, the roll rate sensor, 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, the front impact sensors, the side impact sensors, the roll rate sensor, or the rear safing sensor. The airbags could accidentally deploy and cause damage or injury.
- After a collision where the front airbag, the side airbag, the side curtain airbag, the seat belt buckle tensioner, or the seat belt tensioner deployed, go to Component Replacement/Inspection After Deployment. Service and Repair After a collision where an airbag did not deploy, inspect for any damage or any deformation on the SRS unit, front impact sensors, rear safing sensor, roll rate sensor, and side impact sensors. Replace all damaged parts.
- Do not disassemble the SRS unit, front impact sensors, side impact sensors, driver's seat position sensor, roll rate sensor, rear safing sensor, or front passenger's weight sensors.
- Always install the SRS unit, the driver's seat position sensor, all impact sensors, the roll rate sensor, or the rear safing sensor 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 any of the sensors, and keep them away from dust.
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.
Precautions for Electrical Inspections
- 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 back probe adapter 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.
Front Airbag Connectors
Disconnecting
To release the lock, pull the spring-loaded sleeve (A) toward the stop (B) while holding the opposite half of the connector. Then pull the connector halves apart. Be sure to pull on the sleeve and not on the connector.
Connecting
To reconnect, hold the pawl-side connector, and press on the back of the sleeve-side connector in the direction shown. As the two connector halves are pressed together, the sleeve (A) is pushed back by the pawl (B). Do not touch the sleeve.
Side Airbag Connector

To release the lock, pull the spring-loaded sleeve (A) toward the stop (B) while holding the opposite half of the connector. Then pull the connector halves apart. Be sure to pull on the sleeve and not on the connector half.
Connecting
Hold both connector halves, and press them firmly together until the projection (A) of the sleeve-side connector clicks.
Opening the SRS Unit Shorting Connectors for Diagnosis
Special Tools Required
- SRS short canceller 070AZ-SAA0100
NOTE:
- To prevent damage to the connector cavity, insert a short canceller straight into the cavity from the terminal side.
- Before installing a short canceller, wash it with electrical contact cleaner, then dry it with compressed air.
- Do not use a short canceller if it is damaged.
- Make sure to remove the short canceller before reconnecting the SRS unit connector.
NOTE: Some systems store date 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), B (28P), and C (28P) are disconnected, a short circuit is created in the connector to prevent accidental deployment of an airbag or tensioner. The circuit automatically may need to be opened when diagnosis is performed on the system. Insert a short canceller (070AZ-SAA0100) in the specified cavities when necessary to keep the circuit open for testing.
Terminal numbers are shown from the wire side of the female terminals. Insert the 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.
- Clear 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.
- Never put aftermarket accessories on the seats (covers, pads, seat heaters, lights, etc.).
