Control Unit Input Test
Oisconnect the 8-P connector from the interlock control
unit. Check for good contact between the connector and
socket terminals. lf the terminals 8re OK, make Iollow-
ing input tests at the connector. lf all input tests are OK,
but the problem remains, replace the cont.ol unit,
NOTE: lf the shilt lock solenoid clicks when the ignition
switch is ON and the brake pedal is pushed (shift tever
is in lfl position, accelerator is in rest position), the shiftlock system is electronically normal; test the A/T gear
positaon switch as described on page 23- 134.

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.
