Vehicle Damage Warnings
theseSRS 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
Read the following precautions carefully before performing 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, 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 from another vehicle. 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 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 (if equipped), then write down the audio presets before disconnecting the negative cable from the battery.
- Before returning the vehicle to the customer, enter the anti-theft codes for the audio system (if equipped), then enter the audio presets; 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 or the horn inoperative. Center the cable reel whenever you do the following, for '00-05 models Service and Repair or for '06-09 models. 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 or contamination, 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 removed 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
SRS Unit, Front Impact Sensors ('06-09 models), Driver's Seat Position Sensor ('06-09 models),and Passenger's Weight Sensors ('06-09 models).
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 bump or impact the SRS unit 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, and front impact sensors ('06-09 models). The airbags could accidentally deploy and cause damage or injury.
- After a collision where the front airbags or the seat belt tensioners deployed, go to component Replacement/Inspection after Deployment. Service and Repair After a collision where the airbags did not deploy, inspect for any damage or any deformation on the SRS unit, and the front impact sensors. If there is any damage, replace the SRS unit and/or the sensors.
- Do not disassemble the SRS unit, front impact sensors ('06-09 models), driver's seat position sensor ('06-09 models), and passenger's weight sensors ('06-09 models).
- Always install the SRS unit, driver's seat position sensor and all impact sensors ('06-09 models) 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, and keep it 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 these 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 ('00-05 models)
Some SRS system connectors have a spring-loaded lock.
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
1. 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.

Opening the SRS Unit Shorting Connectors for Diagnosis ('06-09 models)
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 reconnection.
- 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 the SRS unit connector (28P) A is disconnected, a short circuit is automatically created in the connector by its own function to prevent airbag deployment. The circuit may need to be open sometimes when testing 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.
