Pre-tensioner" Service

• Donot use acircuit testertocheck SRScircuits.
• Before servicing theSRS. turnignition switch"OFF", disconnect bothbattery cablesandwait forat
least 10minutes.
For approximately 10minutes afterthecables areremoved, itis still possible forthe airbag to
deploy. Therefore, donot work onany SRS connectors orwires untilatleast 10minutes havepassed.
• For single airbag system, donot separate diagnosis sensorunitfrom steering wheel.
• For dual airbag system. diagnosis sensorunitmust always beinstalled withtheir arrow marks
"Q"

pointing towards thefront ofthe vehicle forproper operation. Alsocheck diagnosis sensorunitfor
cracks. deformities orrust before installation andreplace asrequired.
• The spiral cablemustbealigned withtheneutral position sinceitsrotations arelimited. Donot
attempt toturn steering wheelorcolumn afterremoval ofsteering gear.
• Handle airbag module carefully. Alwaysplaceitwith thepad side facing upward.
• Donot use oldbolts afterremoving anySRS parts; replace withnewones. Conduct self-diagnosis
to check entire SRSforproper function.
• For dual airbag system, instrument panelassembly shouldbereplaced afterairbag inflates.
