Manual Description
POWER SUPPLY, GROUND & CIRCUIT ELEMENTS, wiring Diagram — POWER — 4, bATTERY 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 22, iPDM E/R Power/Ground Circuit Inspection 26.
Removal and Installation IPDM E/R 28, hOW TO READ HARNESS LAYOUT 38, wiring Diagram Codes (Cell Codes) 55, fUSE BLOCK - JUNCTION BOX (J/B)70.
FUSE, FUSIBLE LINK AND RELAY BOX71, aCCESSORY POWER SUPPLY — IGNITION SW, if fuse is blown, be sure to eliminate cause malfunction 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 malfunction, 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 compartment.
IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control, oil, pressure switch signal, and 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.
IPDM E/R receives a request signal from each control unit with CAN communication, parking, license plate, side marker tail lamps, 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, 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, operation of control parts by IPDM E/R during fail-safe mode follows.
With the ignition switch ON, the headlamp (LO) ON, with the ignition switch OFF, the headlamp (LO) OFF, with the ignition switch ON, the parking, license plate, side marker and tail lamps ON, with the ignition switch OFF, the parking, license plate, side marker tail lamps.
With the ignition switch ON, the cooling fan HI operates, with the ignition switch OFF, cooling fan stops, parking, license plate, side marker, until the ignition switch is turned OFF, the front wiper LO and HI remains same status.
It was in just before fail−safe control was initiated, in order to save power, IPDM E/R switches status by itself based each operating condition, q CAN communication is normally performed with other control units.
