Fusible Link
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is questionable, use circuit tester or test lamp. CAUTION: q If fusible link should melt, it is possible that critical circuit (power supply or large current carrying circuit) is shorted. In such a case, carefully check and eliminate cause of incident. q Never wrap outside of fusible link with vinyl tape. Important: Never let fusible link touch any other wiring harness, vinyl or rubber parts.

Circuit Breaker
The PTC thermistor generates heat in response to current flow. The temperature (and resistance) of the thermistor element varies with current flow. Excessive current flow will cause the element's temperature to rise. When the temperature reaches a specified level, the electrical resistance will rise sharply to control the circuit current. Reduced current flow will cause the element to cool. Resistance falls accordingly and normal circuit current flow is allowed to resume.

System Description
q
EKS0080P
IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM) integrates the relay box and the fuse box which has been conventionally placed in the engine room. It controls the built-in relay with the control circuit in IPDM E/R. q IPDM E/R integrated control circuit performs ON-OFF control of the relay and transmission of various signals (oil pressure switch, park/neutral position switch, reverse switch) through CAN communication with BCM and ECM. NOTE: All IPDM E/R integrated relays can never be removed.
SYSTEMS CONTROLLED BY IPDM E/R
1.
2. 3. 4. 5. 6.
Lamp control Using the CAN communication line, it receives signals from BCM and controls following lamps: Headlamps (Hi, Lo) Parking lamps, tail lamps and license plate lamp Front fog lamps Front wiper control Using the CAN communication line, it receives signals from BCM and controls front wiper. Headlamp washer control Using the CAN communication line, it receives signals from BCM and controls headlamp washer. Rear window defogger control Using the CAN communication line, it receives signals from BCM and controls rear window defogger. A/C compressor control Using the CAN communication line, it receives signals from ECM and controls A/C compressor. Cooling fan control Using the CAN communication line, it receives signals from ECM and controls cooling fan.

FAIL-SAFE FUNCTION
q
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 to normal control. Operation of control parts by IPDM E/R during fail-safe mode is as follows:
Controlled parts Headlamp Parking lamp/ license plate lamp/ tail lamp Cooling fan Front wiper Rear window defogger Front fog lamp Headlamp washer A/C compressor Fail-safe mode With the ignition switch ON, the headlamp (low) is ON. With the ignition switch OFF, the headlamp (low) is OFF. With the ignition switch ON, the tail lamp is ON. With the ignition switch OFF, the tail lamp is OFF. With the ignition switch ON, the cooling fan HI operates. With the ignition switch OFF, the cooling fan stops. Until the ignition switch is turned off, the front wiper LO and HI remains in the same status it was in just before fail-safe control was initiated. Rear window defogger is OFF Front fog lamp is OFF Headlamp washer is OFF A/C compressor is OFF

IPDM E/R STATUS CONTROL
G In order to save power, the IPDM E/R switches status by itself based on each operating condition. 1. CAN communication status q CAN communication is normally performed with other control units. H q Individual unit control by the IPDM E/R is normally performed. q When the IPDM E/R is not controlling any load, a sleep request signal is received from the BCM and the mode is switched to sleep waiting status. I 2. Sleep waiting status q Process to stop CAN communication is activated. J q All systems controlled by IPDM E/R are stopped. When 1 second has elapsed after CAN communication with other control units is stopped, mode switches to sleep status. 3. Sleep status PG q The IPDM E/R operates in low current consumption mode. q CAN communication is not active. q When a change in the CAN communication line or ignition switch ON is detected, the mode switches to L CAN communication status.

FUNCTION OF IPDM E/R
Park/neutral position switch signal output function The signal (ON/OFF) input from the Park/neutral position is output to ECM. Oil pressure switch output function The signal (ON/OFF) input from the oil pressure switch is output to the combination meter using the CAN communication line. Reverse switch signal output function The signal (ON/OFF) input from the reverse switch is output to BCM using the CAN communication line.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM) CAN Communication
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

CONCEPT OF AUTO ACTIVE TEST
q
q
IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN communication line. Therefore, when auto active test mode is activated successfully, CAN communication between IPDM E/R and BCM is normal. If any systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed using auto active test.
