DescriptionINFOID:0000000012430674
CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle
multiplex communication system with high data communication speed and excellent error detection ability.
Many electronic control units are equipped into vehicl es, and each control unit shares information and links
with other control units during operation. With CAN co mmunication, control units are connected with two com-
munication lines (CAN-H line, CAN-L line) allowing a hi gh rate of information transmission with less wiring.
Each control unit transmits and receives data but selectively reads required data only. Refer to LAN-30, "
CAN
COMMUNICATION SYSTEM : CAN Communication Signal Chart".

Check CAN communication system. Refer to LAN-16, "
Trouble Diagnosis Flow Chart".
>> Inspection End.
CONSULT name DTCDTC detecting condition Repair order
CAN COMMUNICATION FAILURE U1000 When air bag diagnosis sensor unit is not
transmitting or receiving CAN communi-
cation signals for 2 or more seconds.Refer to SRC-94, "

STARTING SYSTEM (WITH INTELLIGENT KEY)
No.Component part Description
1. IPDM E/R CPU inside IPDM E/R operates the starter control relay when
the ignition switch is in the start position.
2. Transmission range switch (CVT Models) Supplies power to the starter co
ntrol relay (inside IPDM E/R)
when the selector lever is shifted into the P or N position.
3. Starter motor The starter motor plunger closes and the motor is supplied
with battery power, which in turn cranks the engine, when the
S terminal is supplied with electric power.
4. Clutch interlock switch (M/T Models) Clutch interlock switch supplies power to the coil side of the
starter control relay when the clutch pedal is depressed to
crank the engine.

• When the selector lever is in the P or N position, power is supplied to starter relay and starter control relay by
the transmission range switch. The BCM and IPDM E/R (C PU) will detect the selector lever position by the
input signal.
• When the starter operating condition is met, the IPDM E/R will turn the starter control relay ON by starter
control relay control signal.
• When engine cranking condition is met, the BCM turns ON the starter relay by starter control relay signal.
• Then battery power is supplied to starter motor (“S” terminal) through the starter control relay and starter
relay.

• EPS control unit (1) is installed to steering column assembly.
• EPS control unit performs an arithmetical operation on data, such as steering wheel turning force (sensor signal) from the torque
sensor, vehicle speed signal, etc. Then it generates an optimum
assist torque signal to the EPS motor according to the driving con-
dition.
• EPS control unit decreases the output signal to EPS motor while
extremely using the power steering function (e.g., full steering)
consecutively for protecting EPS motor and EPS control unit
(Overload protection control).
