Air Bag(s) Arming and Disarming: Service and Repair

Precautions and Procedures

General Precautions

Read the following precautions carefully before performing airbag system service. If the instructions described are not properly followed, the airbags could accidentally deploy and cause damage or injuries.
- Except when performing electrical inspections, always turn the ignition switch OFF, 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 OFF 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 removing any of the SRS parts (including 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 passenger's airbag.
- The original audio unit has a coded theft protection circuit. Be sure to get the audio unit anti-theft code and write down the audio unit anti-theft code and audio presets before disconnecting the negative cable from the battery.
- Before returning the vehicle to the customer, enter the radio code, and radio station preset, and 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 and the horn inoperative. Center the cable reel 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 or contamination, replace it with a new one. For example, if it does not rotate smoothly, replace the cable reel.

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.

SRS Unit Precautions

- Be careful not to bump or impact the SRS unit whenever the ignition switch is ON (II), or for at least 3 minutes after the ignition switch is turned OFF.

- During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the SRS unit. The airbags could accidentally deploy and cause damage or injury.

- After a collision in which the airbags were deployed, replace the SRS unit and other related components. After a collision in which the airbags were not deployed, inspect for any damage or any deformation on the SRS unit. If there is any damage, replace the SRS unit.
- Do not disassemble the SRS unit.
- Turn the ignition switch OFF, disconnect the negative cable from the battery, and wait at least 3 minutes before beginning installation or replacement of the SRS unit, or disconnecting the connectors from the SRS unit.
- Be sure the SRS unit is installed securely with the mounting 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.
- Store the SRS unit in a cool (less than 104 °F / 40 °C) and dry (less than 80 % relative humidity, no moisture) area.

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 instructions described.

- Never attempt to modify, splice, or repair SRS wiring. If there is an open or damage in 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 grounding 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 a U-shaped probe. Do not insert the probe forcibly.
- Use specified service connectors in troubleshooting. Using improper tools could cause an error in inspection due to poor metal-to-metal contact.

Spring-loaded Lock Connector ('06-07 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

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.

Disconnecting

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 ('06-07 Models)

Special Tools Required
SRS short canceller 070AZ-SAA0100

NOTE:
- To prevent damage of the connector cavity, insert the short canceller straight into the cavity from the terminal side.
- Before installing the short canceller, wash it with electrical contact cleaner or neutral detergent, then air blow dry it.
- Do not use the short canceller if it is damaged.
- Make sure to remove the short canceller before reconnection.

When the SRS unit connector A is disconnected, a short circuit is created in the connector by its own function to prevent an airbag deployment. The circuit may need to be open sometimes when diagnosis is performed on the system.
Insert the short canceller (No. 070AZ-SAA0100) in the specified cavities when it is necessary to keep the circuit open for diagnosis.
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.

Disconnecting System Connectors ('06-07 Models)

Turn the ignition switch OFF, disconnect the negative cable from the battery, and wait at least 3 minutes before beginning the following procedures.
- Before disconnecting the cable reel 4P connector (1), disconnect the driver's airbag 4P connector (2).
- Before disconnecting SRS unit connector B (28P) from the SRS unit, disconnect both seat belt tensioner 2P connectors (3, 4).

('06-07 Models)

1. Disconnect the negative cable from the battery, and wait at least 3 minutes.

Driver's Airbag

2. Remove the access panel from the steering wheel, then disconnect the driver's airbag 4P connector (A) from the cable reel.

Passenger's Airbag

3. Remove the passenger's dashboard lower cover, then disconnect the passenger's airbag 4P connector (A) from the SRS main harness.

Seat Belt Tensioner

4. Remove the roll bar upper trim, then disconnect the seat belt tensioner 2P connector (A) from the SRS main harness.

SRS Unit

5. Remove the center console and audio unit. Disconnect SRS unit connector A (28P) or SRS unit connector B (28P) from the SRS unit.
