Honda HR-V: Precautions and Procedures
SRS PRECAUTIONS AND PROCEDURES (KA/KC)
General Precautions
NOTE: Some systems store data in memory that is lost when
the 12 volt battery is disconnected. Before disconnecting the 12 volt battery,
refer to 12 volt battery Terminal Disconnection and Reconnection.
Please read the following precautions carefully before servicing the SRS, or
the airbags could accidentally deploy and cause damage or injuries.
- Except when doing electrical inspections that requires 12 volt battery
power, always turn the vehicle to the OFF (LOCK) mode, disconnect the
negative cable from the 12 volt battery, then wait at least 3
minutes before starting work.
NOTE: The SRS memory is not erased even if the vehicle is turned to the OFF
(LOCK) mode, or if the 12 volt battery cables are disconnected from the 12 volt
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, remote steering wheel controls, or the horn inoperative. Center the
cable reel whenever you do the following.
- 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 ºF (93 ºC) ).
- Never do electrical tests on 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 or tensioner, refer to Airbag
and Tensioner Disposal.
SRS Unit, Front and Side Impact Sensors, Rear Safing Sensor, Driver's Seat
Position Sensor, and Front Passenger's Weight Sensors
NOTE: Some systems store data in memory that is lost when the 12 volt battery
is disconnected. Before disconnecting the 12 volt battery, refer to 12 volt
battery Terminal Disconnection and Reconnection
- Turn the vehicle to the OFF (LOCK) mode. Disconnect the negative cable
from the 12 volt 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, the front impact sensors,
the side impact sensors, or the rear safing sensor when the vehicle is in
the ON mode, or for at least 3 minutes after the vehicle is
turned to the OFF (LOCK) mode.
- Do not reconnect any connectors to the SRS unit until it is fully
installed, including torquing the bolts.
- 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, or the rear safing sensor. The
airbags could accidentally deploy and cause damage or injury.
- After a collision where the front airbags, the side airbags, the side
curtain airbags, the front seat belt tensioners, or the driver's seat belt
outer lap tensioner deploy, go to Component
Replacement/Inspection After Deployment. After a collision where the 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. If there is any damage, replace the SRS
unit and/or the sensors. Replace all damaged parts.
- Do not disassemble the SRS unit, the front impact sensors, the side
impact sensors, the rear safing sensor, the driver's seat position sensor,
or the front passenger's weight sensors.
- Always install the SRS unit, driver's seat position sensor, all impact
sensors, and the rear safing sensor with the new bolts to the specified
torque.
- Do not spill water or oil on the SRS unit or 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 the 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.
Lever-Locked Connector
The SRS unit connectors have a lever lock.
SRS Unit Connectors
Disconnecting/Connecting
- To release the lock (A), pull the lever (B) while pushing the lock on
the outside of the connector, then pull out the connector (C).
- To reconnect the connector (D), push in on the connector. As the
connector is pressed in, the lever (E) moves to the locked position.
Spring-Loaded Lock Connector
Some SRS connectors have a spring-loaded lock.
Driver's Airbag Connector/Side Curtain Airbag Connector/Front Seat Belt
Tensioner Connector/Selectable Energy Absorption Device Connector
Disconnecting/Connecting
- Pull out on the locking tabs (A) to disconnect the connector (B). Be
careful not to damage the connector.
- Align the guide tab (C) of the connector (D) with the ditch of the other
side, and then connect the connector. Be careful not to damage the
connector.
Front Passenger's Airbag Connector
Disconnecting/Connecting
- 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.
- 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 (C) is pushed back by
the pawl (D). Do not touch the sleeve.
Side Airbag Connector/Driver's Seat Belt Outer Lap Tensioner Connector
Disconnecting/Connecting
- 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.
- Hold both connector halves, and press them firmly together until the
projection (C) of the sleeve-side connector clicks.
Side Curtain Airbags
The front pillar trim and quarter pillar trim with side curtain airbags have
a "SIDE CURTAIN AIRBAG" mark.
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 the airbag assembly.
- Cut, tear, or unwrap the tape strips.
Front Seats With Side Airbags
Front 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. Do
not spray steam on the seats.
- Do not repair a torn or frayed seat-back cover/pad. Replace the
seat-back cover/pad if it is damaged.
- After a collision where the side airbag was deployed, replace the side
airbag and the seat frame with the new parts. If the seat-back cover is
split, it must be replaced. Refer to Component
Replacement/Inspection After Deployment.
- Never put aftermarket accessories on the seats (covers, pads, seat
heaters, lights, etc.).
