DTC CONFIRMATION PROCEDURE
1.PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROC EDURE” occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
With CONSULT
1. Start the engine and wait for 5 seconds or more.
2. Check the DTC.
Is
“U0300” detected?
YES >> Go to TM-295, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000009464247
1.CONTROL UNIT CHECK
Check the number of control units replaced before “U0300” is detected.
Is one control unit replaced?
YES >> The specification of the control unit replac ed may be incorrect. Check the part number and the
specification.
NO >> GO TO 2.
2.CONTROL UNIT CHECK
With CONSULT
1. Remove one of the control unit replaced.
2. Assemble the old control unit before replacement.
3. Turn ignition switch ON, and wait for 2 seconds or more.
4. Select “Self Diagnostic Results” in “TRANSMISSION”.

U1000 CAN COMM CIRCUIT
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000009464248
CAN (Controller Area Network) is a serial communication
line for real-time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehi cle, and each control unit shares information and links
with other control units during operation (not independently ). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H line, CAN-L li ne) allowing a high rate of information transmission
with less wiring. Each control unit transmits/recei ves data but selectively reads required data only.

Unit Description
Combination switch (lighting
and turn signal switch) Transmits the lighting switch signal to the BCM.
Combination meter • Receives a buzzer output signal from the BCM with CAN communication and sounds the buzz-
er.
• Receives the seat belt buckle switch signal from the seat belt buckle switch LH (driver seat) and transmits it to the BCM via CAN communication.
• Judges whether the parking brake is released using the vehicle speed signal and the parking brake switch signal, and sounds the buzzer if necessary.
BCM Based on the signals received from various units and switches, transmits the buzzer output signal
to the combination meter via CAN communication.

DescriptionINFOID:0000000009941189
COMBINATION METER SE LF-DIAGNOSIS MODE
The following meter functions can be checked during Combination Meter Self-Diagnosis Mode:
• Pointer sweep of speedometer, tachometer and gauges.
• Illumination of all LCD segments and color patterns for meter displays.
• Illumination of all lamps/LEDs that are controlled by the combination meter (regardless of switch status).
STARTING COMBINATION METER SELF-DIAGNOSIS MODE
NOTE:
• Check combination meter power supply and ground circuits if self-diagnosis mode does not start. Refer to
MWI-58, "COMBINATION METER : Diagnosis Procedure"
. Replace combination meter if power supply and
ground circuits are found to be normal and self-diagnosis mode does not start. Refer to MWI-82, "Removal
and Installation".
• Combination meter self-diagnosis mode will function with the ignition switch in ON. Combination meter self-
diagnosis mode will exit upon turning the ignition switch to OFF.
How to Initiate Se lf-Diagnosis Mode
1. Press and hold the trip reset switch while turning the ignition switch ON. After 2 seconds release trip reset
switch, then press the trip reset switch 3 times withi n 7 seconds after the ignition switch is turned ON.
2. When the diagnosis function is activated, the meter illuminates all of the following:
• Warning lights/indicators.
• Meter assembly.
• Information display color bars red, green, blue and white (1).
• Odometer, trip A/B odometers and CVT indicator LCD display segments (2).
3. Pressing and holding the trip reset switch performs the pointer sweep test.
CONSULT Function (METER/M&A)INFOID:0000000009941190
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and no-start condition.

The front wiper is controlled by each function of BCM and IPDM E/R.
Control by BCM
• Combination switch reading function
• Front wiper control function
Control by IPDM E/R
• Front wiper control function
• Relay control function
FRONT WIPER BASIC OPERATION
• BCM detects the combination switch conditi on by the combination switch reading function.
• BCM transmits the front wiper request signal to IPDM E/R with CAN communication depending on each
operating condition of the front wiper.
• IPDM E/R turns ON/OFF the integrated front wiper rela y and the front wiper high relay according to the front
wiper request signal. IPDM E/R provides the power supply to operate the front wiper HI/LO operation.

SYSTEM
*: When without vehicle speed setting
FRONT WIPER AUTO STOP OPERATION
• BCM stops transmitting the front wiper request signal when the front wiper switch is turned OFF.
• IPDM E/R detects the front wiper auto stop signal fr om the front wiper motor and detects the front wiper
motor position (stop position/except stop position).
• When the front wiper request signal is stopped, IPDM E/R turns ON the front wiper relay until the front wiper
motor returns to the stop position.
NOTE:
• BCM stops the transmitting of the front wi per request signal when the ignition switch OFF.
• IPDM E/R turns the front wiper rela y OFF when the ignition switch OFF.
FRONT WIPER OPERATION LINKED WITH WASHER
• BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the
washer linked operating condition of the front wiper.
• BCM transmits the front wiper request signal (LO) so that the front wiper operates approximately 2 times
when the front washer s witch OFF is detected.
Washer linked operating condition of front wiper- Ignition switch ON
- Front washer switch ON (0.4 second or more)
• IPDM E/R turns ON the integrated front wiper rela y according to the front wiper request signal (LO).
• The front washer motor is grounded through the combinat ion switch when the front washer switch is ON.
REAR VIEW CAMERA WASHER CONTROL UNIT (if equipped)
• Rear view camera washer control unit detects the co mbination switch condition by the combination switch
reading function.
• Rear view camera washer control unit supplies power and ground to operate the front washer motor.
