voltage is displayed.

ACCEL SEN 2 signal is con-
verted by ECM internally. Thus, it
differs from ECM terminal voltage
signal. ACCEL SEN 2 [V]×
THRTL SEN 1 [V]××

The throttle position sensor signal voltage is
displayed.

THRTL SEN 2 signal is con-
verted by ECM internally. Thus, it
differs from ECM terminal voltage
signal. THRTL SEN 2 [V]×
FUEL T/TMP SE
[°C] or [°F]×

The fuel temperature (determined by the sig-
nal voltage of the fuel tank temperature sen-
sor) is displayed.
INT/A TEMP SE
[°C] or [°F]××

The intake air temperature (determined by the
signal voltage of the intake air temperature
sensor) is indicated.

[ON/OFF]××

Indicates [ON/OFF] condition of the air condi-
tioner switch as determined by the air condi-
tioner signal.
P/N POSI SW
[ON/OFF]××

Indicates [ON/OFF] condition from the park/
neutral position (PNP) switch signal.
PW/ST SIGNAL
[ON/OFF]××

[ON/OFF] condition of the power steering sys-
tem (determined by the signal sent from EPS
control unit) is indicated.
LOAD SIGNAL
[ON/OFF]××

Indicates [ON/OFF] condition from the electri-
cal load signal.
ON: Rear window defogger switch is ON and/
or lighting switch is in 2nd position.
OFF: Both rear window defogger switch and
lighting switch are OFF.
IGNITION SW
[ON/OFF]×

Indicates [ON/OFF] condition from ignition
switch.
HEATER FAN SW
[ON/OFF]×

Indicates [ON/OFF] condition from the heater
fan switch signal.
BRAKE SW
[ON/OFF]×

compensated by ECM according to the input
signals.
When the engine is stopped, a
certain computed value is indi-
cated.
IGN TIMING [BTDC]

Indicates the ignition timing computed by ECM
according to the input signals.
When the engine is stopped, a
certain value is indicated.
CAL/LD VALUE [%]

“Calculated load value” indicates the value of
the current airflow divided by peak airflow.

HEADLAMP (FOR CANADA) - DAYTIME LIGHT SYSTEM -PFP:26010
Component Parts and Harness Connector LocationEKS00ICD
System DescriptionEKS00ICE
Headlamp operation is controlled by the BCM (body control module) based on inputs from the combination
switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM receives an input sig-
nal requesting the headlamps (and tail lamps) illuminate. The request is then communicated to the IPDM E/R
(intelligent power distribution module engine room) via the CAN communication lines. The CPU (central pro-
cessing unit) located in the IPDM E/R controls ground for the headlamp high and headlamp low relay coils.
These relays direct power to the respective headlamps, which then illuminate. When the headlamp switch is
OFF or in the 1ST position (parking lamps ON), the parking brake is released and the engine is running, the
IPDM E/R de-energizes the headlamp relays and supplies ground to the daytime light relay 1 to actuate the
daytime light function.
OUTLINE
Power is supplied at all times

to headlamp high relay RH and LH (located in IPDM E/R)

to headlamp low relay (located in IPDM E/R) and

to ignition relay (located in IPDM E/R)

through 15A fuse (No. 52, located in IPDM E/R) and

through 20A fuse (No. 53, located in IPDM E/R)

to CPU located in IPDM E/R,

through 40A fusible link (letter g , located in fuse and fusible link box)

to BCM terminal 70,

through 10A fuse [No. 8, located in fuse block (J/B)]

to BCM terminal 57,

through 10A fuse [No. 13, located in fuse block (J/B)]

to combination meter terminal 27,

through 10A fuse (No. 26, located in fuse and fusible link box)

to the daytime light relay 1.
With the ignition switch in the ON or START position, power is supplied
