Details of time display
CRNT: Displays when there is a malfunction now or after returning to the normal condition until turning igni-
tion switch OFF → ON again.
PAST: Displays when there is a malfunction that is detected in the past and stored.
1 - 39: Displayed if any previous malfunction is present when current condition is normal. It increases like 1
→ 2 → 3...38 → 39 after returning to the normal condition whenever ignition switch OFF → ON. The counter
remains at 39 even if the number of cycles exceeds it. It is counted from 1 again when turning ignition switch
OFF → ON after returning to the normal condition if the malfunction is detected again.

position.
2. Return lighting switch to off position, and insert key into key switch.
Does warning chime sound for both steps?
YES >> GO TO 2
NO >> Replace combination meter. Refer to MWI-94, "
Removal and Installation".
2.CHECK SEAT BELT WARNING LAMP
1. Turn ignition switch ON.
2. Check the operation of the seat belt warning lamp in the combination meter.
Is the inspection result normal?
YES >> Replace BCM. Refer to BCS-57, "Removal and Installation of BCM".
NO >> GO TO 3
3.CHECK SEAT BELT BUCKLE SWITCH CIRCUIT
Perform inspection of the seat belt buckle switch circuit. Refer to WCS-24, "
DiagnosisProcedure".
Is the inspection result normal?
YES >> GO TO 4
NO >> Repair harness or connector.
4.CHECK SEAT BELT BUCKLE SWITCH UNIT
Perform a unit inspection for the seat belt buckle switch. Refer to WCS-25, "
Component Inspection".
Is the inspection result normal?
YES >> Replace the combination meter. Refer to MWI-94, "Removal and Installation".
NO >> Replace the seat belt buckle switch (driver side).Seat belt fastened : OFF
Seat belt not fastened : ON

THE KEY WARNING DOES NOT SOUND
DescriptionINFOID:0000000001722960
Key warning does not sound even though key is in ignition and front door (driver side) is opened.
Diagnosis ProcedureINFOID:0000000001722961
1.CHECK WARNING CHIME OPERATION
With key removed from the ignition and the front door (driver side) open, turn the lighting switch to 1st or 2nd
position.
Does warning chime sound?
YES >> GO TO 2
NO >> Replace combination meter. Refer to MWI-94, "
Removal and Installation".
2.CHECK KEY SWITCH CIRCUIT
Perform inspection of the key switch circuit. Refer to WCS-26, "
DiagnosisProcedure" (with Intelligent Key) or
WCS-28, "
DiagnosisProcedure" (without Intelligent Key).
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair harness or connector.
3.CHECK KEY SWITCH
Perform a unit inspection for the key switch. Refer to WCS-27, "
Component Inspection" (with Intelligent Key)
or WCS-29, "
Component Inspection" (without Intelligent Key).
Is the inspection result normal?
YES >> Replace the BCM. Refer to BCS-57, "Removal and Installation of BCM".
NO >> Replace the key switch and ignition knob switch (with Intelligent Key) or key switch and key lock
solenoid (without Intelligent Key).

FRONT WIPER AND WASHER SYSTEM
System DiagramINFOID:0000000001366592
System DescriptionINFOID:0000000001366593
OUTLINE
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 condition 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 relay 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.
FRONT WIPER LO OPERATION
BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the
front wiper LO operating condition.
Front wiper LO operating condition
- Ignition switch ON
- Front wiper switch LO or front wiper switch MIST (while pressing)
IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
FRONT WIPER HI OPERATION
BCM transmits the front wiper request signal (HI) to IPDM E/R with CAN communication according to the
front wiper HI operating condition.
Front wiper HI operating condition
- Ignition switch ON
- Front wiper switch HI
IPDM E/R turns ON the integrated front wiper relay and the front wiper high relay according to the front wiper
request signal (HI).

BCM transmits the front wiper request signal (INT) to IPDM E/R with CAN communication according to the
front wiper INT operation condition and the intermittent operation delay interval judged value.
Front wiper INT operating condition- Ignition switch ON
- Front wiper switch INT
Intermittent operation delay interval judgment- BCM calculates the intermittent operation delay interval from the vehicle speed signal received from the
wiper dial position and the combination meter with CAN communication.
IPDM E/R turns the integrated front wiper relay ON so that the front wiper is operated only once according to
the front wiper request signal (INT).
BCM detects stop position/except stop position of the front wiper motor according to the front wiper stop
position signal received from IPDM E/R with CAN communication.
BCM transmits the front wiper request signal (INT) again after the intermittent operation delay interval after
the front wiper motor is stopped.
FRONT WIPER AUTO OPERATION (IF EQUIPPED)
BCM receives the wiping speed request signal from the rain sensor with the light and rain sensor serial link.
BCM judges the auto wiping condition depending on the wiping speed request signal and the rain sensor
sensitivity setting under front wiper AUTO operating condition.
BCM transmits the front wiper request signals (LO or HI) to the IPDM E/R through CAN communication line
according to the auto wiping condition.
NOTE:
When the wiper volume is turned down at 1 level with front wiper AUTO operating condition, BCM transmits
front wiper request signal (LO) to IPDM E/R with CAN communication.
Front wiper AUTO operating condition- Ignition switch ON
- Front wiper switch AUTO
Rain sensor sensitivity setting- BCM determines rain sensor sensitivity according to a wiper volume.
