DIAGNOSIS AND REPAIR WORKFLOW
Work FlowINFOID:0000000003806024
DETAILED FLOW
1.OBTAIN INFORMATION ABOUT SYMPTOM
Interview the customer to obtain as much malfunction information (conditions and environment when the mal-
function occurred) as possible when the customer brings the vehicle in.
>> GO TO 2.
2.CHECK DTC
Perform self diagnosis with CONSULT-III
Is any DTC detected?
YES >> Refer to BCS-74, "DTCIndex"
NO >> GO TO 3.
3.REPRODUCE THE MALFUNCTION INFORMATION
Check the malfunction on the vehicle that the customer describes.
Inspect the relation of the symptoms and the condition when the symptoms occur.
>> GO TO 4.
4.IDENTIFY THE MALFUNCTIONING SYSTEM WITH “SYMPTOM DIAGNOSIS”
Use “Symptom diagnosis” from the symptom inspection result in step 3. Then identify where to start perform-
ing the diagnosis based on possible causes and symptoms.
>> GO TO 5.
5.IDENTIFY MALFUNCTIONING PARTS WITH “COMPONENT DIAGNOSIS”
Perform the diagnosis with “Component diagnosis” of the applicable system.
>> GO TO 6.
6.REPAIR OR REPLACE THE MALFUNCTIONING PARTS
Repair or replace the specified malfunctioning parts.
>> GO TO 7.
7.FINAL CHECK
Check that malfunctions are not reproduced when obtaining the malfunction information from the customer,
referring to the symptom inspection result in step 3.
Are all malfunctions corrected?
YES >> INSPECTION END
NO >> GO TO 4.

REAR WINDOW DEFOGGER SYSTEM
WITH AV CONTROL UNIT
WITH AV CONTROL UNIT : System DiagramINFOID:0000000003806025
WITH AV CONTROL UNIT : System DescriptionINFOID:0000000003806026
Operation Description
 Turn rear window defogger switch ON when the ignition switch is turned ON. Then multifunction switch (rear
window defogger switch) transmits rear window defogger switch signal to AV control unit via AV communica-
tion. AV control unit transmits rear window defogger switch signal to BCM via CAN communication.
 BCM turns rear window defogger relay ON and transmits rear window defogger control signal to IPDM E/R
via CAN communication when rear window defogger switch signal is received.
 Rear window defogger and door mirror defogger are supplied with power and operate when rear window
defogger relay turns ON.
 IPDM E/R transmits rear window defogger control signal to AV control unit via CAN communication.
 When receiving the signal, AV control unit indicates rear defogger ON on the display. At the same time, AV
control unit transmits rear defogger control signal to multifunction switch (rear window defogger switch) via
AV communication and illuminates rear defogger switch indicator.
Timer function
 BCM turns rear window defogger relay ON for approximately 15 minutes when rear window defogger switch
is turned ON. It makes rear window defogger and door mirror defogger (with door mirror defogger) operate.
 Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns
rear window defogger relay OFF. The same reaction also occurs during timer operation, if the ignition switch
is turned OFF.

Operation Description
 Turn rear window defogger switch ON when the ignition switch is turned ON. Then A/C control unit (rear win-
dow defogger switch) transmits rear window defogger switch signal to A/C auto amp. and BCM.
 BCM turns rear window defogger relay ON and transmits rear window defogger control signal to IPDM E/R
via CAN communication when rear window defogger switch signal is received.
 Rear window defogger and door mirror defogger are supplied with power and operate when rear window
defogger relay turns ON.
 Rear window defogger relay transmits rear window defogger control signal to A/C auto amp. when rear win-
dow defogger operates.
 When receiving the signal, A/C auto amp. indicates rear defogger ON on the display. At the same time, A/C
auto amp. transmits rear defogger control signal to A/C control unit (rear window defogger switch) and illumi-
nates rear defogger switch indicator.
Timer function
 BCM turns rear window defogger relay ON for approximately 15 minutes when rear window defogger switch
is turned ON. It makes rear window defogger and door mirror defogger (with door mirror defogger) operate.
 Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns
