Precautions and Procedures
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 (see page 22-68).
Please read the following precautions carefully before
servicing the airbag system. If the instructions
described in this manual are not properly followed, or
the airbags could accidentally deploy and cause
damage or injuries. Except when doing 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. 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.
 The original audio and navigation system have a coded theft protection circuit. Make sure you have the
anti-theft codes for the audio system or navigation
system (if equipped), then write down the audio
presets before disconnecting the negative cable from
the battery.
 Before returning the vehicle to the client, enter the anti-theft codes for the audio system or navigation
system (if equipped), then enter the audio presets; set
the clock.
 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 (see step 6
on page 24-202).
– 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.

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 (see page 22-68).
 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, 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, 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 airbag, the side
airbag, or a the seat belt tensioner, the seat belt
buckle tensioner deployed, go to Component
Replacement/Inspection after Deployment (see page
24-185). After a collision where an airbag did not
deploy, inspect for any damage or any deformation
on the SRS unit, the front impact sensors, the side
impact sensors, or the rear safing sensor. 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, and 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, and keep them away from dust.

NOTE:
 To prevent damage to the c onnector cavity, insert
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 (see page 22-68).
When SRS unit connectors A (28P) and B (28P) are
disconnected, a short circuit is automatically created in
the connector by its own function to pr event an 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

DTC (Diagnostic Trouble Codes) Reading the DTC
Precautions
24-22SRS
General Troubleshooting Information
A
The self-diagnostic function of the SRS system allows it
to locate the causes of system problems and store this
information in memory. For easier troubleshooting, this
data can be retrieved via a data link circuit.
 When you turn the ignition switch to ON (II), the SRS indicator comes on. If it goes off after 6 seconds, the
system is normal, and is not currently detecting any
abnormality.
 If there is an abnormality, the system locates and defines the problem, stores this information in
memory, and turns on the SRS indicator. The data
remains in memory even if the ignition switch is
turned off or the battery is disconnected.
 The data is stored in memory as a diagnostic trouble code (DTC).
 The ‘‘x’’ at the end of each DTC denotes a numeric character (0 thru 9) or an alpha character (A thru F)
that is displayed on the HDS.
 DTCs are either latching or resetting depending on the malfunction. With resetting DTCs, the SRS
indicator goes off the next time the ignition switch is
turned to ON (II), and the system is normal, but the
DTC is still stored. With latching DTCs, the SRS
indicator does not turn to LOCK (0) until the
malfunction is repaired and the DTC is cleared.
 When you connect the HDS to the data link connector (DLC), you can retrieve a more detailed DTC in the
HDS ‘‘SRS’’ menu.
NOTE: Only read DTCs from the SRS menu, not from
the SWS menus. SWS (ODS unit) DTCs are subcodes
of SRS unit DTCs. Only troubleshoot the
corresponding SRS DTCs.
 After reading and recording the DTC, proceed with the troubleshooting procedure for that code.
 Use only a digital multimeter to check the system. Make sure its output is 10 mA (0.01 A) or less when
switched to the smallest value in the ohmmeter range.
A tester with a higher output could damage the
airbag circuit or cause accidental airbag deployment
and possible injury.  Whenever the ignition switch is in ON (II), or has been
turned to LOCK (0), for less than 3 minutes, be careful
not to bump the SRS unit; the airbags could
accidentally deploy and cause damage or injuries.
 Before removing the dashboard wire harness, floor wire harness, disconnect the driver’s airbag
connector, the front passenger’s airbag connector,
both side airbag connectors, both side curtain airbag
connectors and both seat belt tensioner connectors.
 Make sure the battery is fully charged. If the battery is dead or low, electrical measurements may not be
correct.
 Do not touch a tester probe to the terminals in the SRS unit or harness connectors, and do not connect
the SRS unit terminals or the sensor terminals with a
jumper wire. Use only the backprobe set and the
multimeter. Backprobe spring-loaded lock type
connectors correctly.
1. Make sure the ignition switch is in LOCK (0).
2. Connect the HDS to the data link connector (DLC) (A).
3. Turn the ignition switch to ON (II).
4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate,
troubleshoot the DLC circuit (see page 11-204).
