Manual Description
POWER SUPPLY, GROUND & CIRCUIT ELEMENTS, (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" 2, wiring Diagram - POWER - 5, circuit Breaker (Built Into BCM) 16.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)17, function of Detecting Ignition Relay Malfunction 18, terminal and Reference Value IPDM E/R 24, iPDM E/R Power/Ground Circuit Inspection 27.

Removal and Installation IPDM E/R 28, fUSE AND FUSIBLE LINK BOX 79, 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 and SB section Service Manual.

To avoid rendering the SRS inoperative, which could increase the risk of personal injury death, the event of a collision which 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.

For detailed ground distribution, refer PG-30, "Ground Distribution", bATTERY POWER SUPPLY — IGNITION SW, aCCESSORY POWER SUPPLY — IGNITION SW, iGNITION POWER SUPPLY — IGNITION SW.

If fuse is blown, be sure to eliminate cause incident before, use fuse of specified rating, do not partially install fuse, always insert it into fuse holder properly, 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 or by feeling with finger tip, questionable, use circuit tester test lamp, if fusible link should melt, it is possible that critical circuit (power supply large current carrying.

Never wrap outside of fusible link with vinyl tape, never let fusible link touch any other wiring harness, vinyl rubber parts, for example, when current is 30A, the circuit is broken within 8 20, a circuit breaker is used following systems.

The PTC thermistor generates heat in response current flow, temperature (and resistance) of the thermistor element varies with, electrical resistance will rise sharply to reduce circuit current, this reduced current flow will cause the element cool lowering.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM), iPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE, 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, oil, 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.

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 rear window defogger, using CAN communication lines, it receives signals from the ECM and controls A/C compressor, using CAN communication lines, it receives signals from the BCM 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.
