System voltage out of rangeSystem voltage* of ventilation seat control unit
is out of operation range (8.5 V - 16.5 V) When system voltage* returns within nor-
mal range after more than 0.5 seconds,
system recovers
 When recovering, system returns to the
same status as previous

DIAGNOSIS AND REPAIR WORKFLOW
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 for BCM and IPDM E/R.
2. Perform the following procedure if DTC is detected.
- 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.
Are any symptoms described and any DTC detected?
Symptom is described, DTC is detected>>GO TO 3.
Symptom is described, DTC is not detected>>GO TO 4.
Symptom is not described, DTC is detected>>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 detected 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 SEC-175, "
DTCInspectionPriorityChart", and determine trouble
diagnosis order.
NOTE:
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 7.
NO >> Refer to GI-35, "
Intermittent Incident".
6.DETECT MALFUNCTIONING SYSTEM BY SYMPTOM TABLE
Detect malfunctioning system according to SEC-192, "
Symptom Table" based on the confirmed symptom in
step 4, and determine the trouble diagnosis order based on possible causes and symptom.
>> GO TO 7.
7.DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
Inspect according to Diagnostic Procedure of the system.
NOTE:
The Diagnostic Procedure described is 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 8.
NO >> Check voltage of related BCM terminals using CONSULT-III.
8.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 replace-
ment.
3. Check DTC. If DTC is detected, erase it.
>> GO TO 9.
9.FINAL CHECK
When DTC is detected in step 2, perform DTC Confirmation Procedure or Component Function Check again,
and then check that the malfunction has 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 7.
YES (Symptom remains)>>GO TO 6.
NO >> INSPECTION END

ECM RE-COMMUNICATING FUNCTION
ECM RE-COMMUNICATING FUNCTION : DescriptionINFOID:0000000003814900
Performing the following procedure can automatically perform re-communication of ECM and BCM, but only
when the ECM has been replaced with a new one (*1).
*1: New one means a virgin ECM which has never been energized on-board.
(In this step, initialization procedure by CONSULT-III is not necessary)
NOTE:
When registering new Key IDs or replacing the ECM that is not brand new, refer to CONSULT-III Oper-
ation Manual NATS-IVIS/NVIS.
If multiple keys are attached to the key holder, separate them before beginning work.
Distinguish keys with unregistered key IDs from those with registered IDs.
ECM RE-COMMUNICATING FUNCTION : Special Repair RequirementINFOID:0000000003814901
1.PERFORM ECM RE-COMMUNICATING FUNCTION
1. Install ECM.
2. Insert the registered Intelligent Key (*2), turn ignition switch to “ON”.
*2: To perform this step, use the key that has been used before performing ECM replacement.
3. Maintain ignition switch in the “ON” position for at least 5 seconds.
4. Turn ignition switch to “OFF”.
5. Start engine.
Can engine be started?
YES >> Procedure is completed.
NO >> Initialize control unit. Refer to CONSULT-III Operation Manual NATS-IVIS/NVIS.

INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION
System DiagramINFOID:0000000003814902
System DescriptionINFOID:0000000003814903
 The engine start function of Intelligent Key system is a system that makes it possible to start and stop the
engine without removing the key. It verifies the electronic ID using two-way communication when pressing
the push-button ignition switch while carrying the Intelligent Key, which operates based on the results of
electronic ID verification for Intelligent Key using two-way communication between the Intelligent Key and
the vehicle.
NOTE:
The driver should carry the Intelligent Key at all times.
 Intelligent Key has 2 IDs [for Intelligent Key and for NVIS (NATS)]. It can perform the door lock/unlock oper-
ation and the push-button ignition switch operation when the registered Intelligent Key is carried.
 When the Intelligent Key battery is discharged, it can be used as emergency back-up by inserting the Intelli-
gent Key to the key slot. At that time, perform the NVIS (NATS) ID verification. If it is used when the Intelli-
gent Key is carried, perform the Intelligent Key ID verification.
 If the ID is successfully verified, and when push-button ignition switch is pressed, steering lock will be
released and starting the engine will be possible.
 If the door lock/unlock operation is performed when the Intelligent Key battery is discharged, all doors lock/
unlock can be performed by operating the driver door key cylinder using the mechanical key set in the Intel-
ligent Key.
 Up to 4 Intelligent Keys can be registered (Including the standard Intelligent Key) on request from the owner.
NOTE:
 Refer to SEC-9, "
System Description" for any functions other than engine start function of Intelligent Key
system.
PRECAUTIONS FOR INTELLIGENT KEY SYSTEM
In the Intelligent Key system, the transponder [the chip for NVIS (NATS) ID verification] is integrated
into the Intelligent Key. (For the conventional models, it is integrated into the mechanical key.) There-
fore, the mechanical key cannot perform the ID verification, and thus it cannot start the engine.
Instead, the NVIS (NATS) ID verification can be performed by inserting the Intelligent Key into the key
slot, and then it can start the engine.
OPERATION WHEN INTELLIGENT KEY IS CARRIED
1. When the push-button ignition switch is pressed, the BCM signals the inside key antenna and transmits
the request signal to the Intelligent Key.
2. The Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to the BCM via
the remote keyless entry receiver.
3. The BCM receives the Intelligent Key ID signal and verifies it with the registered ID.
