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 18, function of Detecting Ignition Relay Malfunction 19, iNSPECTION IN AUTO ACTIVE TEST MODE 24, check IPDM E/R Power Supply Ground Circuit 29.
Removal and Installation IPDM E/R 31, component Parts and Harness Connector Location 32, pUSH-BUTTON IGNITION SWITCH OPERATING PROCEDURE 32, wiring Diagram — PDU — 34.
Terminals and Reference Value Intelligent Key, terminals and Reference Value PDU 37, check PDU Power Supply Ground Circuit 39, check Push-Button Ignition Switch (Ignition Switch).
Check Push-Button Ignition Switch (Indicator Circuit) System 41, pDU Communication Circuit System 1 42, pDU Communication Circuit System 2 43, removal and Installation PDU 44.
HOW TO READ HARNESS LAYOUT 62, nAVIGATION SUB-HARNESS & A/C HARNESS 69, eNGINE CONTROL HARNESS (VQ ENGINE) 77, eNGINE CONTROL HARNESS (VK ENGINE) 80.
Wiring Diagram Codes (Cell Codes) 95, fUSE BLOCK - JUNCTION BOX (J/B) 114, fUSE, FUSIBLE LINK AND RELAY BOX 115, 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 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, it receives signal from BCM and controls following lamps, q Tail, parking license plate lamps.
Daytime light relay control (for Canada models), using CAN communication, it receives signals from BCM and controls daytime light relay, using CAN communication, it receives signals from BCM and controls front wipers.
