minutes before beginning work.

NOTE: The SRS unit memory is not erased even if the ignition



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

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.



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

TROUBLESHOOTING INTERMITTENT FAILURES

If there was a malfunction, but it does not recur, it will be stored in the memory as
an intermittent failure, and the SRS indicator will come on.

After checking the DTC, troubleshoot as follows:

1. Read the DTC (see "READING THE DTC ").

2. Erase the DTC memory (see "ERASING THE DTC MEMORY ").

3. With the shift lever in neutral, start the engine, and let the engine idle.

4. The SRS indicator comes on for about 6 seconds and then goes off.

5. Shake the related wire harness and connectors, and look for loose connections,
pin fits, and poor grounds.

6. Take a test-drive (quick acceleration, quick braking, and cornering), turn the
steering wheel fully left and right, and hold it there for 5 to 10 seconds. If the
problem recurs, the SRS indicator will come on.

NOTE: A faulty cable reel can cause intermittent connection

SYSTEM DESCRIPTION

SRS COMPONENTS

The SRS is a safety device which, when used in conjunction with the seat belt, is
designed to help protect the driver and passenger in a frontal impact exceeding a
certain set limit. The system consists of the SRS unit, including a safing sensor and
an impact sensor (A), the cable reel (B), the driver's airbag (C) and the passenger's
airbag (D). The seat belt tensioner (E) is linked with the SRS airbags to further
increase the effectiveness of the seat belt. In a front-end collision, the tensioner

3.

The inflators must ignite and deploy the airbags and activate the tensioners.

SRS OPERATION

The main circuit in the SRS unit senses and judges the force of impact and, if
necessary, ignites the inflator charges. If battery voltage is too low or power is
disconnected due to impact, the voltage regulator and the back-up power circuit
respectively will keep voltage at a constant level.

For the SRS to operate

1. The impact sensor must activate and send electronic signals to the
microprocessor.

2. The microprocessor must compute the signals and send them to the airbag
inflators and seat belt tensioners.

diagnosis circuit is built into the SRS unit; when the ignition switch is turned

seconds, or if it comes on while driving, it indicates an abnormality in the SRS. The

Self-diagnosis System

A self­ON (II), the SRS indicator comes on and goes off after about 6 seconds, if the SRS
is operating normally. If the indicator does not come on, or does not go off after 6

SRS must be inspected and repaired as soon as possible. For better serviceability,
the memory will store the cause of the malfunction, and the data link circuit passes
on information from memory to the 16P data link connector (DLC). This
information can be read with the HDS connected to the 16P data link connector
(DLC) (see GENERAL TROUBLESHOOTING INFORMATION ).

NOTE: Before you disconnect the battery negative cable, make

sure you have the anti-theft code for the radio, and then
write the audio presets.
