Manual Description
POWER SUPPLY, GROUND & CIRCUIT ELEMENTS, wiring Diagram — POWER — 5, bATTERY POWER SUPPLY — IGNITION SW, iGNITION POWER SUPPLY — IGNITION SW.
SYSTEMS CONTROLLED BY IPDM E/R 17, function of Detecting Ignition Relay Malfunction 23, iNSPECTION IN AUTO ACTIVE TEST MODE 24, iPDM E/R Power/Ground Circuit Inspection 29.
Removal and Installation IPDM E/R 30, hOW TO READ HARNESS LAYOUT 43, wiring Diagram Codes (Cell Codes) 60, fUSE BLOCK - JUNCTION BOX (J/B)77.
FUSE, FUSIBLE LINK AND RELAY BOX78, this vehicle is equipped with the automatic window adjusting function, automatically lowers slightly to avoid contact between the window and the side roof panel, closed, the window will automatically raise slightly.
On vehicles equipped with the automatic window adjusting function, lower both the driver front passenger, side windows before disconnecting the battery cables, and the roof panel when either door opened/closed, after the battery cables are disconnected, do not open/close the driver and/or front passenger door.
With the window in the full up position, side roof panel may be damaged, aCCESSORY POWER SUPPLY — IGNITION SW, 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 compartment, iPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control, etc, it controls operation of each electrical part via 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.
