Precautions for Supplemental Restraint System (SRS) AIR BAG” SEAT, 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 and SB section Service Manual, to avoid rendering the SRS inoperative, which could increase the risk of personal injury death, improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system.
Do not use electrical test equipment on any circuit related to the SRS unless instructed, when you read wiring diagrams, refer following, refer to "How to Read Wiring Diagrams" GI section, refer to "POWER SUPPLY ROUTING CIRCUIT" power distribution.
When you perform trouble diagnosis, refer following, refer to "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" GI section, refer to "How to Perform Efficient Diagnosis for an Electrical Incident" GI section, for detailed ground distribution, refer PG-29, "Ground Distribution".
ACCESSORY POWER SUPPLY — IGNITION SW, iPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM), iPDM E/R (Intelligent Power Distribution Module Engine Room) integrates the relay box fuse block, which were originally placed in engine compartment.
IPDM E/R-integrated control circuits perform ON-OFF operation of relays, CAN communication control, it controls operation of each electrical component via ECM, BCM CAN communication lines, none of the IPDM E/R integrated relays can be removed, using CAN communication lines, it receives signals from the BCM and controls following lamps.
Q Tail lamps license lamps, using CAN communication lines, it receives signals from the BCM and controls front wipers, using CAN communication lines, it receives signals from the BCM and controls heated mirror relay, using CAN communication lines, it receives signals from the ECM and controls A/C compressor.
Using CAN communication lines, it receives signals from the ECM and controls starter relay, using CAN communication lines, it receives signals from the ECM and controls cooling fan relays, using CAN communication lines, it receives signals from the BCM and controls horn relay, with CAN communication, by connecting each control unit using two communication lines (CAN L-line, CAN.
H-line), it is possible to transmit a maximum amount of information with minimum wiring, transmit and receive data, and reads necessary information only, q When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control.
