Manual Description
(SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" 2, dIAGNOSIS AND REPAIR WORK FLOW 9, precaution for Supplemental Restraint System (SRS) "AIR BAG" "SEAT BELT, the Supplemental Restraint System such as AIR BAG” and SEAT BELT PRE-TENSIONER”, used along.
With a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger certain, system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front, air bag, depending on the severity of a collision and whether the front occupants belted unbelted, information necessary to service the system safely is included in the SRS AIR BAG” and SEAT BELT”.
Always observe the following items preventing accidental activation, to avoid rendering the SRS inoperative, which could increase the risk of personal injury death, the event of a collision that would result in air bag inflation, all maintenance must be performed by, improper maintenance, including incorrect removal and installation of the SRS, can lead personal.
Injury caused by unintentional activation of the system, never use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual, pRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS, when working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with.
Ignition ON or engine running, never use air or electric power tools or strike near sensor(s) with, when using air or electric power tools or hammers, always switch the ignition OFF, disconnect, battery, and wait at least 3 minutes before performing any service, for operating instructions, refer Technical.
Refer to "BODY CONTROL SYSTEM : Component Parts Location", cPU inside IPDM E/R controls starter control relay, refer to "IPDM E/R : Component Parts Location", the starter motor plunger closes and the motor supplied with battery.
Power, which in turn cranks the engine, when the S” terminal is supplied with electric power, tCM supplies power to the starter relay and starter control relay inside, iPDM E/R when the selector lever is shifted to the P N position, refer to "CVT CONTROL SYSTEM : Component Parts Location".
TCM transmits shift position signal to BCM and IPDM E/R, when selector lever is in the P N position, iPDM E/R supplies power supply to starter relay and starter control relay, when shift position signal, when starter operating condition is satisfied, IPDM E/R turns starter control relay ON by starter control relay, when engine cranking condition is satisfied, BCM turns starter relay ON by starter control relay control signal.
Then battery power is supplied to starter motor (S” terminal) through starter control relay starter relay, dIAGNOSIS AND REPAIR WORK FLOW, to ensure a complete and thorough diagnosis, the battery, starter motor and alternator test segments must be, done as a set start finish.
Perform the starting system test with Starting/Charging System Tester (SST: J-44373), cHARGE BATTERY>>Perform the slow battery charging procedure, rEPLACE BATTERY>>Before replacing battery, clean the battery cable clamps battery posts, check that the starter motor operates correctly.
YES >> Starter motor OK, check that starter motor operates, yES >> Check ring gear and starter motor drive pinion, compare the engine coolant temperature and the cranking voltage with specifications.
Minimum Specification of Cranking Voltage Referencing Coolant Temperature, more than (More than 34), is the voltage less than specified value, does the starter motor turn smoothly.
Check that the engine can be rotated by hand, does the engine turn freely by hand, >> Perform further diagnosis of engine mechanical or powertrain mechanism, the B” terminal is constantly supplied with battery power.
Perform diagnosis under the condition that engine cannot start by following procedure, check that starter motor B” terminal connection clean tight, check voltage between starter motor B” terminal ground.
