service. Observe the instructions described in this manual, or the airbags could
accidentally deploy and cause damage or injuries.
Except when performing electrical inspections, always turn the ignition switch
OFF and disconnect the negative cable from the battery, and wait at least 3
minutes before beginning work.
NOTE: The SRS unit memory is not erased even if the ignition
switch is turned OFF or the battery cables are
disconnected from the battery.
Use the 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.

Before removing any of the SRS parts (including disconnection of the
connectors), always disconnect the airbag and seat belt tensioner 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.
After reconnecting the battery negative cable, if the IMA battery level gauge
(BAT) displays no segments; remove the No. 15 EPS (40 A) fuse from the
under-hood fuse/relay box, then start the engine, and hold it between 3,500
RPM and 4,000 RPM without load (in park or neutral) until the BAT displays

Cable Reel Alignment
Misalignment of the cable reel could cause an open in the wiring, making the
SRS system and the horns inoperative. Center the cable reel whenever the
following is performed (see step 6 ).
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 on 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 the airbag during service, please observe the following
Store the removed airbag with the pad surface up. Never put any things on the
or water.

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
damage or any deformation on the SRS unit. If there is any damage, replace the
SRS unit.

The self-diagnostic function of the SRS system allows it to locate the causes of
system problems and then store this information in memory. For easier
troubleshooting, this data can be retrieved via a data link circuit.
When you turn the ignition switch ON (II), the SRS indicator will come on. If
it goes off after 6 seconds, the system is normal.
If there is an abnormality, the system locates and defines the problem, stores
this information in memory, and turns the SRS indicator on. The data will
remain in the memory even when the ignition switch is turned off or if the
battery is disconnected.
When you connect the HDS to the 16P data link connector (DLC) to short the
SCS terminal, and turn the ignition switch ON (II), the SRS indicator will
indicate the diagnostic trouble code (DTC) by the number of blinks.
When you connect the HDS to the 16P data link connector (DLC), you can
retrieve the DTC in the "SRS" menu in the HDS.
After reading and recording the DTC, proceed with the troubleshooting
procedure for the code indicated.
Precautions
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 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.
minutes, be careful not to bump the SRS unit; the airbags could accidentally
deploy and cause damage or injuries.
Before you remove the SRS harness, disconnect the driver's airbag connector,
the passenger's airbag connector and seat belt tensioner connectors.
Make sure the battery is sufficiently charged. If the battery is dead or low, the
measuring values 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 terminals with a jumper wire. Use only the
prompts in the "SRS" menu. If the tester indicates no DTC, DTC 9

The DTC consists of a main code and a sub code.
Including the most recent problem, up to three different DTCs can be
indicated.
In case of a continuous failure, the DTC will be indicated repeatedly (see
example 1).
In case the system is normal (no DTC), the SRS indicator will stay on (see

If a continuous and an intermittent failure occur, both DTCs will be
indicated as continuous failures.

If the SRS indicator does not come on as indicated above, always check
for an open or a short to ground in the SCS circuit before troubleshooting
the system.
