DETAILED FLOW

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 Check BCM for DTCs. Perform the following procedure if DTC is displayed. Erase DTC. Study the relationship between the cause detected by DTC and the symptom described by the customer. 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. If two or more DTCs are detected, refer to " «DTC INSPECTION PRIORITY CHART»(ref-396327-S41360212262011050400000) " (BCM) and determine trouble diagnosis order. Is DTC detected? YES: GO TO 8 . NO: Refer to " «INTERMITTENT INCIDENT»(ref-396282-S12471740572011050400000) ".
6. PERFORM BASIC INSPECTION Perform Basic Inspection. Refer to " «BASIC INSPECTION»(ref-396327-S40102766952011050400000) ". GO TO 7.
7. DETECT MALFUNCTIONING SYSTEM BY SYMPTOM TABLE Detect malfunctioning system according to Symptom Table based on the confirmed symptom in step 4. GO TO 8.
8. DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE Inspect according to Diagnostic Procedure of the system. NOTE: The Diagnostic Procedure is described based on open circuit inspection. A short circuit inspection is also required for the circuit check in the Diagnostic Procedure. GO TO 9.
9. REPAIR OR REPLACE THE MALFUNCTIONING PART Repair or replace the malfunctioning part. Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair and replacement. Check DTC. If DTC is displayed, erase it. GO TO 10.
10. FINAL CHECK When DTC was detected in step 9, perform DTC Confirmation Procedure or Component Function Check again, and then check that the malfunctions have been fully repaired. When symptom was described by the customer, refer to the 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.

PRECAUTIONS FOR KEY REGISTRATION

1. The key registration is a procedure that erases the current NATS ID once, and then re-registers a new ID. Therefore the registered key is necessary for this procedure. Before starting the registration operation collect all registered Keys from the customer.
2. The NATS ID registration is the procedure that registers the ID stored into the transponder (integrated in mechanical key) to BCM. The key ID registration is the procedure that registers the ID to the BCM.
3. When performing the key system registration only, the engine cannot be started by inserting the key into the key cylinder. When performing the NATS registration only, the engine cannot be started by using the ignition key.

SECURITY INDICATOR

1. Always flashes with ignition key in the OFF position.

Disarmed Phase

When the vehicle is being driven or when doors are open, the theft warning system is set in the disarmed phase on the assumption that the owner is inside or near the vehicle.

Pre-Armed Phase And Armed Phase

The vehicle security system turns into the pre-armed phase when ignition switch is in OFF position, all doors are closed and locked (using keyfob, door lock/unlock switch, driver key cylinder or auto relock function). The system automatically shifts into the armed phase.

Condition of Activating The System

When the following condition is performed in armed phase, the system sounds the horns and flashes the headlamps for about 50 seconds.

1. Any door is opened.

Condition of Deactivating The System

When one of the following operations is performed, the armed phase is canceled.

1. Unlock the doors with keyfob.
2. Use the mechanical key to unlock the driver door using the door key cylinder.

CAN COMMUNICATION CONTROL

When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-safe control. After CAN communication recovers normally, it also returns to normal control.

If No CAN Communication Is Available With BCM

FAIL SAFE CHART

IGNITION RELAY MALFUNCTION DETECTION FUNCTION

1. IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.
2. IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation coil circuit.
3. If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to alert the user to the ignition relay malfunction when the ignition switch is turned OFF.

IGNITION RELAY MALFUNCTION REFERENCE

Note. The tail lamp turns OFF when the ignition switch is turned ON.

FRONT WIPER CONTROL

IPDM E/R detects front wiper stop position by a front wiper auto stop signal.

When a front wiper auto stop signal is in the conditions listed below, IPDM E/R stops power supply to wiper after repeating a front wiper 10 second activation and 20 second stop five times.

FRONT WIPER CONTROL REFERENCE

Note. This operation status can be confirmed on the IPDM E/R "DATA MONITOR" that displays "Block" for the item "WIP PROT" while the wiper is stopped.

STARTER MOTOR PROTECTION FUNCTION

IPDM E/R turns OFF the starter control relay to protect the starter motor when the starter control relay remains active for 90 seconds.

CONDITIONS OF VEHICLE (OPERATING CONDITIONS)

1. Ignition switch is not turned ON.
2. Ignition key is not inserted into key cylinder.

SYMPTOM CHART

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the SRS AIRBAG and SEAT BELTS articles.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

NATS ANTENNA AMP

Note. If NATS antenna amp. is not installed correctly, NVIS (NATS) system will not operate properly and "SELF-DIAG RESULTS" on CONSULT - III screen will show "LOCK MODE" or "CHAIN OF IMMU-KEY" Initialization is not necessary when only the NATS antenna amp. is replaced with a new one.
