POWER SUPPLY, GROUND & CIRCUIT ELEMENTS, wiring Diagram - POWER - 4, bATTERY POWER SUPPLY - IGNITION SW, aCCESSORY POWER SUPPLY - IGNITION SW.
IGNITION POWER SUPPLY - IGNITION SW, sYSTEMS CONTROLLED BY IPDM E/R 17, function of Detecting Ignition Relay Malfunction 18, iNSPECTION IN AUTO ACTIVE TEST MODE 23.
IPDM E/R Power/Ground Circuit Inspection 27, removal and Installation IPDM E/R 29, hOW TO READ HARNESS LAYOUT 39, wiring Diagram Codes (Cell Codes) 55.
FUSE BLOCK - JUNCTION BOX (J/B) 69, fUSE, FUSIBLE LINK AND RELAY BOX70, if fuse is blown, be sure to eliminate cause incident before, 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 by, 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 and eliminate cause incident, never wrap outside of fusible link with vinyl tape, never let fusible link touch any other wiring harness, vinyl.
The PTC thermistor generates heat in response current flow, temperature (and resistance) of the thermistor element varies with, electrical resistance will rise sharply to control circuit current, reduced current flow will cause the element cool.
Accordingly and normal circuit current flow allowed resume, 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 room.
IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control, oil, pressure switch signal, hood switch signal reception, etc, it controls operation of each electrical part via ECM, BCM CAN communication lines, none of the IPDM E/R-integrated relays can be removed.
Using CAN communication line, it receives signal from BCM and controls following lamps, using CAN communication line, it receives signals from BCM and controls front wipers, using CAN communication line, it receives signals from BCM and controls rear window defogger, using CAN communication line, it receives signals from ECM and controls A/C relay.
Using CAN communication line, it receives signals from ECM and controls cooling fan relay, using CAN communication line, it receives signals from BCM 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 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, after CAN communication recovers normally, it also returns normal control, q Operation of control parts by IPDM E/R during fail-safe mode follows.
With the ignition switch ON, the headlamp (low) ON, with the ignition switch OFF, the headlamp (low) OFF, with the ignition switch ON, the tail and parking lamps ON, with the ignition switch OFF, the tail and parking lamps OFF.
With the ignition switch ON, the cooling fan HI operates, with the ignition switch OFF, cooling fan stops, until the ignition switch is turned off, the front wiper LO and HI remains in same status it.
