DIAGNOSIS AND REPAIR WORKFLOW
[INTELLIGENT KEY SYSTEM]
1.GET INFORMATION FOR SYMPTOM
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred).
>> GO TO 2.
2.CHECK DTC
1. Check DTC.
2. Perform the following procedure if DTC is displayed.
- Record DTC and freeze frame data (Print them out with CONSULT-III.)
- Erase DTC.
- Study the relationship between the cause detected by DTC and the symptom described by the customer.
3. Check related service bulletins for information.
Is any symptom described and any DTC detected?
Symptom is described, DTC is displayed>>GO TO 3.
Symptom is described, DTC is not displayed>>GO TO 4.
Symptom is not described, DTC is displayed>>GO TO 5.
3.CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in “DATA MONITOR” mode and check real time diagnosis results.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 5.
4.CONFIRM THE SYMPTOM

Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in “DATA MONITOR ” mode and check real time diagnosis results.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 6.
5.PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC Confirmation Procedure for the displayed DTC, and then check that DTC is detected again.
At this time, always connect CONSULT-III to the vehicle, and check diagnostic results in real time.
If two or more DTCs are detected, refer to DLK-163, "
diagnosis order.
NOTE:
• Freeze frame data is useful if the DTC is not detected.
• Perform Component Function Check if DTC Confirmation Procedure is not included in Service Manual. This
simplified check procedure is an effective alternative though DTC cannot be detected during this check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC Confirmation Procedure.
Is DTC detected?
YES >> GO TO 8.
NO >> Refer to GI-39, "
Intermittent Incident".
DTC Inspection Priority Chart" and determine trouble
6.PERFORM BASIC INSPECTION
Perform DLK-188, "

8.DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
Inspect according to Diagnostic Procedure of the system.
NOTE:
The Diagnostic Procedure described based on open circuit inspection. A short circuit inspection is also
required for the circuit check in the Diagnostic Procedure.
Is malfunctioning part detected?
YES >> GO TO 9.
NO >> Check voltage of related BCM terminals using CONSUL T-III.
9.REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair and replacement.
3. Check DTC. If DTC is displayed, erase it.
>> GO TO 10.
10.FINAL CHECK
When DTC was detected in step 2, perform DTC Confirmation Procedure or Component Function Check
again, and then check that the malfunction have been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and check that
the symptom is not detected.
Does the symptom reappear?
YES (DTC is detected)>>GO TO 8.
YES (Symptom remains)>>GO TO 6.
NO >> INSPECTION END

DOOR REQUEST SWITCH : System Description INFOID:0000000000961092
Only when pressing the request switch, it is possible to lock and unlock the door by carrying the Intelligent
Key.
• The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function) by carrying the Intelligent Key, which operates based on the results of electronic ID verification using two-way communications between the Intelligent Key and the vehicle (BCM).
CAUTION:
The driver should always carry the Intelligent Key
• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver (Warning chime function).
• When a door lock is locked, unlocked or trunk open with request switch or remote controller button operation, the hazard lamps flash and the Intelligent Key warning buzzer or horn sounds (Hazard and buzzer/horn

• It is possible to perform a diagnosis on the system and register an Intelligent Key with the CONSULT-III.
OPERATION DESCRIPTION/DOOR LOCK/UNLOCK
• When the BCM detects that each door request switch is pressed, it starts the outside key antenna and inside
key antenna corresponding to the pressed door request switch and transmits the request signal to the Intelligent Key. And then, check that the Intelligent Key is near the door.
• If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and
transmits the key ID signal to the BCM via remote keyless entry receiver.
• BCM receives the key ID signal and compares it with the registered key ID.

• The Intelligent Key system is a system that makes it possible to open the trunk (trunk open function) by carrying the Intelligent Key which operates based on the results of electronic ID verification using two-way communications between the Intelligent Key and the vehicle. (BCM)
CAUTION:
The driver should always carry the Intelligent Key
• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver. (Warning chime functions)
• When a trunk open with request switch or remote controller button operation, the hazard lamps flash and the
Intelligent Key warning buzzer or horn sounds (Hazard and buzzer/horn reminder function).
• The settings for each function can be changed with the CONSULT-III.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be
registered.
• It is possible to perform a diagnosis on the system and register an Intelligent Key with the CONSULT-III.
OPERATION DESCRIPTION/TRUNK OPEN
• When the BCM detects that trunk open request switch is pressed, it starts the outside key antenna (trunk
room) and inside key antenna corresponding to the pressed trunk open request switch and transmits the

COMPONENT DIAGNOSIS
U1000 CAN COMM CIRCUIT
Description INFOID:0000000000961120
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.
