Make sure iacks and safety stands ate placed plopel-
ly and hoist brackets are attached to the correct po-
sitions on the engine {see section 11,

CAUTION:
. Use fender covers to avoid damaging painted sur-
faces.
Unplug the wiring connectors carelully while holding
the coupler and the connector portion to avoid d8m-
age.
Mark all wiring and hoses to avoid misconnection.
Also. be sure that they do not contact other wiring
or hoses, or intedere with other parts.
NOTE: Anti-theft radios have a coded theft protection cir-
cuit. Be sure to get the customer's code number betore- Disconnecting the battery.- Removing the No.32 (7.5 A) fuse from the under
hood fuse/relay box.
Removing the radio
After service, reconnect power to the radio and turn it
on. When the word "CODE" is displayed, enter the cus
tomer's 5-digit code to restore radio operation.
1. Remove the hood (see section 20).
3.Disconnect the battery negative terminal first, then
the positive terminal.
Disconnect the battery cables Irom the under-hood

The Integra SRS includes a driver's airbag located in the steering wheel hub and a passenger's airbag located inthe dashboard above the glove box,
Information necessary to safely service the SRS is included in this Service Manual. ltems marked with an asterisk(*) on the contents page include, or are located near, SRS components. Servicing, dissssembling or replacing
these items will require special pr6cautions and tools, and should therefore be done by an authorized Acura dealer.

Troubleshooting
Tips and Precautions
Never try to disconnect connectors by pulling on their
wires; pull on lhe connector halves instead.
Alwavs reinstall Dlastic covers.
Before connecting connectors, make sure the termi-
nals are in Dlace and not bent.
a Check lor loose retainer and rubber seals.
The backs of some connectors are packed with
grease. Add grease if needed. lf the grease is contami-
nated, reolace it.

Bef ore Troubleshooting
a Check applicable tuses in the appropriate fuse/relay
box.
Check the battery for damage, state of charge, and
clean and tight connections.
Check the alternator belt tension.
CAUTION:
a Do not quick-charge a battely unless the battery
ground cable has been disconnected. otherwise
you will damage the alternator diod€s.
a Do not attempt to crank the engine with the bat-
tery ground cable loosely connected or you willse-
verely damage the wiring.
a The originsl radio has a coded theft plotection cir-
cuit. Be sure to get the customel's code numbel
before- disconnecting the battsry.- removing the No. 47 (7.5 A) fuse from tho
under-hood luse/relay box.- removing the radio.
Atter service. leconnect Dower to the radio and
tum it on. When the word "CODE" is displayed,
enter the customer's 5-digit code to restore radio
ooeration.
Handling Connectors
a Make sure the connectors are clean and have no loose
wire terminals.
a Make sure multiple cavity connectors are packed with
grease (except watertight connectors).
a All connectors have push-down release type locks.
LOCKING TAB
LOCKING TAB
Some connectors have a clip on their side used to at-
tach them to a mount bracket on the body or on
another component. This clip has a pull type lock.
Some mounted connectors cannot be disconnected
unless you tirst release the lock and remove the con-
nector from its bracket.

NOTE: Refer to page 23-123 for the wiring description of
the low fuel indicator circuit.
1. Park car on level ground.
@ oo not smoke whilc wolking on the
fuel system. Keep open tlames away from your work
area. Drain fuel only into an approved container.
2. Drain fuel into an approved container. Then install
the drain bolt with a new washer.
3. Add lessthan 8.2 t l2.2U.S.Gal, 1.8 lmp.Gal)of fuel
and turn the ignition switch ON {ll). The low fuel in-
dicator light should come on within lour minutes.
. lf the light does not come on. remove the access
panel and disconnect the 3P connector from the
fuel gauge sending unit. Connect the A (BLV
WHT) terminal to the C (BLU,/WHT) terminal with
a jumper wire.
- lf the Iight comes on, the problem is either the
sending unit or its ground.- lf the light does not come on, the problem is
an open in the BLU/WHT wire to the gauge as-
sembly, no power to the gauge, or a blown
bulb.
a lf the light comes on, add approx.4 ! (1.1
U.S.Gal. O.9 lmp.Gal) of fuel, the light should go
off within four minutes.

Engine Coolant Temperature (ECT) Gauge
Gauge Test
NOTE: Refer to page 23-123 for the wiring description of
the engine coolant temperature (ECT) gauge circuit dia-
gram.
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testing.
2. Make sure the ignition switch is OFF, then discon-
nect the YEL/GRN wire trom the ECT gauge send-
ing unit and ground it with a jumper wire.
YEL/GRN WIRESENDING UNIT
Turn the ignition switch ON (ll).
Check that the pointer of the ECT gauge starts mov-
ing toward the "H" mark.
CAUTION: Turn the ignition switch OFF before the
pointer reaches "H" on the gauge dial. Failure to do
so may damage the gauge.
a lf the pointer of the gauge does not move at all,
check lor an open in the YEL or YEL/GRN wire.
lf the wires are OK, replace the ECT gauge.
a lf the ECT gauge works, test the ECT sending
unrt.
ECT Sending Unit Test
Disconnect the YEL/GRN wire from the ECT send-
ing unit.
With the engine cold, use an ohmmeter to measure
resistance between the positive terminal and the en-
gine (ground).
Check the temperature ol the coolant.
Run the engine and measure the change in resistance
with the engine at operating temperature (the radi-
ator fan comes on).
5. It the obtained readings are substantially different
from the sDecifications above, replace the ECT send-
Ing unrt.
