.
6.UNIT REPRODUCIBILITY INSPECTION
Perform the following procedure for each unit on the CAN network, and then perform reproducibility test.
1. Turn ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Disconnect the unit connector.
4. Connect the battery cable to the negative terminal.
5. Make sure that the symptom filled in the “Symptom” of the check sheet is reproduced. (Do not confuse it
with the symptom related to removed unit.)
6. Make sure that the same symptom is reproduced.
Inspection results
Reproduced>>Install removed unit, and then check the other unit.
Not reproduced>>Replace removed unit.
IPDM E/R Ignition Relay Circuit InspectionEKS00O5C
Check the following. If no malfunction is found, replace the IPDM E/R.
lIPDM E/R power supply circuit. Refer toPG-24, "Check IPDM E/R Power Supply and Ground Circuit". 6 – Ground : Continuity should not exist.

HEADLAMP -CONVENTIONAL TYPE-PFP:26010
Component Parts and Harness Connector LocationEKS00P7H
System DescriptionEKS00P7I
The control of the headlamp system operation is dependent upon the position of the combination switch (light-
ing switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives
input requesting the headlamps (and tail lamps) illuminate. This input is communicated to the IPDM E/R (intel-
ligent power distribution module engine room) through the CAN communication. The CPU (central processing
unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. When energized, these relays
direct power to the respective headlamps, which then illuminate.
OUTLINE
Power is supplied at all times
lto ignition relay (located in IPDM E/R)
lto headlamp high relay (located in IPDM E/R) and
lto headlamp low relay (located in IPDM E/R), from battery directly,
lthrough 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57,
lthrough 20A fuse (No. 52, located in IPDM E/R) and
lthrough 20A fuse (No. 53, located in IPDM E/R)
lto CPU (located in IPDM E/R),
lthrough 10A fuse (No. 19, located in fuse and fusible link box)
lto combination meter terminal 3.
With the ignition switch in the ON or START position, power is supplied
lto ignition relay (located in IPDM E/R),
lthrough 10A fuse [No. 1, located in fuse block (J/B)]
lto BCM terminal 3,
lthrough 10A fuse [No. 14, located in fuse block (J/B)]
