Replacement
Disconnect the 3-P connector trom the vehicle speed
sensor {VSS).
Remove ihe two mounting bolts, then remove the
VSS.
InstSll in the revsrse order of removal.
NOTE: The VSS drive link is a very small paru
caretul not to lose it.

Engine Oil Pressure Switch Test
1. Remove the YEL/RED wile from the engine oil pres-
sure switch.
ENGI'{E OIL PRESSURE SWITCH
Check tor continuitv between the positive torminal
and the engine {gtound) with the ignhion swhch OFF.
a lf there is continuity, go to step 3.
a lf there is no continuity, replace the switch.
Check for continuity again, this time with th€ engine
runnrng.
a lf there is continuity, go to step 4,
a lf there is no continuity, the switch is OK.
Make sure engine oil level is OK, then check engin€
oil pressure (s€e section 8).
a lf engine oil pressure is OK, replace the switch'
a lf engine oil pressure is low, check the sngine oil
pump (see section 8) and, if necessary, replac€ it.

Engine Oil Pressure
Indicator System
Description
NOTE: Reter to page 23-144 tor the circuit diagram otthe engine oil pressure indicator flasher, snd to page
23-148 lor the input test of the flasher circuit.
The low engine oil pressure indicator tight works in twoways. lt will flash continuously following a momentaryloss of oil pressure, or it will go on and stay on with acomplete loss of oil pressure.
When the engine first starts, before oil Dressure risesabove 29.4 kP8 10.3 kgf/cmr, 4.3 psi), current flowsthrough the low engine oil pressure indicator light andthe oil pressure switch to ground. This tests the circuit.
Wilh the engine running, voltage is applied ro the ftash-er circuit of the integrated control unit. With normal oilpressure, the oil pressure switch is open and the low en-gine oil pressure indicator light does not operate. lf theoil pressure switch closes momentarily (more than O.5secondsl, but then opens again, terminal "yEL/RED,'will
sense ground through the switch. The integrated con-trol unit willthen provide and remove ground for th€ lowengine oil pressure indicator light through terminal"YEL/RED". The light will flash on and olf until the igni-tion switch is turned to "OFF".
lf engine oil pressure falls below 29.4 kPa (O.3 kgJ/cmr,4.3 psi) and does not increase, the oil pressure switchwillstsy closed. The low engine oilpressure indicator lightwill go on and stav on.
NOTE; Refer to page 23-122lot the engine oil pressure
switch test.
Lights-on Reminder
System
Description
Chime Test
Remove the dashboard lower cover and knee bolster
{see page 23-70).
Disconnect the 2-P connector t.om the dashboardwire hamess.
Test the chime by connecting battery power to the"A" te.minal and ground to the "B" terminal, andcycling the power on-off repestedly.
lf the chime fails to sound every time power is cy-cled, reDlace it.
NOTE: Refer to page 23-145 tor a diagram of the lights-
on reminder circuit, and to page 23-149 for the input
tests of the circuit.
When the ignition key is turned to OFF 8nd removed. withthe lights on, voltage is apptied to the reminder circuitin the integrat€d control unit. When you open the driver,sdoor, the circuit senses ground through the closed doorswitch.
With voltage at the "H" terminal, ground at the"GRN/BLU2" terminal and no voltage at the ,,F,' termi-nal, the chime sounds to remind the driver to turn oJf thelights.

General Precautions
Carefully inspect any SRS part before you install it.Do not install any part that shows signs of beingdropped or improperly handled, such as dents, cracksor deformation:
- Airbag assembly {driver's and front passenger's)
Airbag Handling and Storage
Do not try to disassemble the airbag assembly. lt has noserviceable parts. Once an airbag has been operated(deployed), it cannot be repaired or reuseo.
For temporary storage of the airbag assembly duringservice, please observe the following precautions:
. Store the removed airbag assembly with the pad sur-face up.
!@ It the airbag is impropsrty stored facsdown, accidental deployment could propel the unit withenough force to cause setious iniury
Store the removed airbag assembly on a secure flatsufface away from any high heat source (exceeding
212"Fl1OO'Cl and free of any oil. grease, detergent or
CAUTION: lmproper handling or storage can internallydamage the airbag assembly, making it inoperativ€.ll you suspect the airbag assembly has been damagod,install a new unit and rgler to the Deployment/DigposalProcedures lor disposing of the dsmaged airbag.
Use only a digital multimeter to check the system. lfit's not a Honda multimeter make sure its output is 10mA (0.01 A) or less when switched to the smallestvalue in the ohmmeter range. A tester with a higheroutput could damage the airbag circuit or cause accidental deployment and possible injury.
Do not install used SRS parts from another car. Whenmaking SRS repai.s, use only new pans.
Except when performing electrical inspections,always disconnect both the negative cable and posi-
tive cable at the battery before beginning work.
Replacement of the combination light andwiper/washer switches and cruise control switch canbe done without removing the steering wheell

The original radio has a coded theft protection circuit.Be sure to get the customer's code number beforedisconnecting the battery.
When reinstalling the SRS unit cover, be sure it snapstogether properly.
