General Description

AIRBAG SYSTEM (DIAGNOSTICS)

3. General Description

A: CAUTION

• When servicing a vehicle, be sure to turn the ig-

nition switch to OFF, disconnect the ground cable

from battery, and wait for 60 seconds or more be-

fore starting work.

• The airbag system is fitted with a backup power

supply. After disconnecting the battery ground ca-

ble, the airbag may deploy if you do not wait for 60

seconds or more before starting airbag system ser-

vicing.

• If sensors, airbag module, airbag control module,

pretensioner or harness is deformed or damaged,

replace with new parts.

• Do not use the airbag system and pretensioners

on other vehicles. When replacing parts, be sure to

replace them with new parts.

• When  checking  the  airbag  system,  be  sure  to

use a digital circuit tester. Use of an analog circuit

tester may cause the airbag to activate erroneously

due to a minimal current inside tester.

• When checking, use a test harness (1). Damage

to connector terminal causes malfunction. Do not

directly  put  the  tester  probe  on  airbag  connector

terminal.

• Do not drop any airbag component, store them

under high temperature of 85°C (185°F) or more, or

let  water,  oil  or  grease  get  on  them;  the  internal

parts  may  be  damaged  or  the  reliability  may  be

greatly lowered.

General Description

AIRBAG SYSTEM (DIAGNOSTICS)

• If damage, open circuit or rust is found on airbag

system  wiring  harness,  do  not  use  a  soldering

equipment  to  repair.  Replace  the  faulty  harness

with a new genuine part.

• Install the wiring harness securely with the spec-

ified clips to avoid interference or tangled with other

parts.

• Do not allow water or oil to come in contact with

the connector terminals. Also, do not touch the con-

nector terminals.

• Do not disassemble driver’s airbag module, pas-

senger’s  airbag  module,  side  or  curtain  airbag

modules, or pretensioner.

• The airbag module cannot be used again if de-

ployed once.

• After removal, keep the airbag module with the

pad side facing upward on a dry, clean and flat sur-

face  away  from  heat,  light  sources,  moisture  and

dust.

• Do not check continuity of the airbag modules for
