Supplemental Restraint System (SRS) AIR BAG” SEAT BELT PRE-TENSIONER”, the Supplemental Restraint System such as AIR BAG” and SEAT BELT PRE-TENSIONER” used along with, a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger certain types, the Supplemental Restraint System consists of driver air bag module (located in the center of the steering wheel), front passenger air bag module (located on the instrument panel on passenger side), seat belt.
Pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness spiral cable, the Supplemental Restraint System consists of side air bag module (located in the outer side front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision), wiring harness, warning lamp (one of components of air bags frontal collision).
Information necessary to service the system safely is included in the RS section Service Manual, ¼ To avoid rendering the SRS inoperative, which could increase the risk of personal injury death, ¼ Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system, when you read wiring diagrams, refer following.
¼ HOW TO READ WIRING DIAGRAMS”, ¼ POWER SUPPLY ROUTING” power distribution circuit, when you perform trouble diagnosis, refer following, ¼ HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES”.
¼ HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT”, check for any Service bulletins before servicing vehicle, the tab-locking type connectors help prevent accidental looseness disconnection, the tab-locking type connectors are disconnected by pushing or lifting the locking tab(s).
Refer to the next page for description of slide-locking type connector, do not pull the harness when disconnecting connector, a new style slide-locking type connector is used on certain systems components, especially those, ¼ The slide-locking type connectors help prevent incomplete locking and accidental looseness disconnection.
¼ The slide-locking type connectors are disconnected by pushing or pulling the slider, nORMAL OPEN, NORMAL CLOSED AND MIXED TYPE RELAYS, relays can mainly be divided into three types: normal open, normal closed mixed type relays, bATTERY POWER SUPPLY — IGNITION SW.
Wiring Diagram — POWER — (Cont'd), aCCESSORY POWER SUPPLY — IGNITION SW, iGNITION POWER SUPPLY — IGNITION SW, if fuse is blown, be sure to eliminate cause problem.
Do not partially install fuse; always insert it into fuse, remove fuse for ELECTRICAL PARTS (BAT)” vehicle, not used for a long period time, a melted fusible link can be detected either by visual inspection.
¼ If fusible link should melt, it is possible that critical circuit, (power supply or large current carrying circuit) shorted, in such a case, carefully check eliminate cause, ¼ Never wrap outside of fusible link with vinyl tape.
The PTC thermister generates heat in response current flow, the temperature (and resistance) of thermister element varies, level, the electrical resistance will rise sharply control circuit, reduced current flow will cause the element cool.
Falls accordingly and normal circuit current flow allowed, for removal and installation of spiral cable, refer RS-18, installation — Air Bag Module Spiral Cable”.
