DIAGNOSIS AND REPAIR WORK FLOW

1.

GET INFORMATION FOR SYMPTOM

1.

Get detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurs).

2.

Check operation condition of the function that is malfunctioning.

>> GO TO 2.

2.

CHECK DTC

1.

Check DTC.

2.

Perform the following procedure if DTC is detected.

-

Record DTC and freeze frame data (Print them out using CONSULT.)

-

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

Try to confirm the symptom described by the customer.
Also study the normal operation and fail-safe related to the symptom.
Verify relation between the symptom and the condition when the symptom is detected.

>> GO TO 5.

4.

CONFIRM THE SYMPTOM

Try to confirm the symptom described by the customer.
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 to the vehicle, and check self diagnostic results in real time.
If two or more DTCs are detected, refer to 

BCS-81, "DTC Inspection Priority Chart"

, and determine trouble

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 on 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 CONFIR-
MATION PROCEDURE.

Is DTC detected?

YES

>> GO TO 7.

NO

>> Check according to 

GI-40, "Intermittent Incident"

.

6.

DETECT MALFUNCTIONING SYSTEM BY SYMPTOM DIAGNOSIS

Detect malfunctioning system according to SYMPTOM DIAGNOSIS based on the confirmed symptom in step
4, and determine the trouble diagnosis order based on possible causes and symptom.

Is the symptom described?

YES

>> GO TO 7.

NO

>> Monitor input data from related sensors or check voltage of related module terminals using CON-

SULT.

System Description

INFOID:0000000009945045

SYSTEM DESCRIPTION

• PDS (POWER DISTRIBUTION SYSTEM) is the system that BCM controls with the operation of the push-

button ignition switch and performs the power distribution to each power circuit. This system is used instead
of the mechanical power supply changing mechanism with the operation of the conventional key cylinder.

• The push-button ignition switch can be operated when Intelligent Key is in the following condition. Refer to

Engine Start Function for details.

- Intelligent Key is in the detection area of the interior antenna
- Intelligent Key backside is contacted to push-button ignition switch.
• The push-button ignition switch operation is input to BCM as a signal. BCM changes the power supply posi-

tion according to the status and operates the following relays to supply power to each power circuit.

- Ignition relay (inside IPDM E/R)
- Ignition relay
- ACC relay
- Blower fan relay

NOTE:
The push-button ignition switch operation changes due to the conditions of brake pedal, selector lever and
vehicle speed.

• The power supply position can be confirmed with the lighting of the indicators near the push-button ignition

switch.

BATTERY SAVER SYSTEM

When all the following conditions are met for 60 minutes, the battery saver system will cut off the power supply
to prevent battery discharge.
• The ignition switch is in the ACC position
• All doors are closed
• Selector lever is in the P position

Reset Condition of Battery Saver System

In order to prevent the battery from discharging, the battery saver system will cut off the power supply when all
doors are closed, the selector lever is on P position and the ignition switch is left on ACC position for 60 min-
utes. If any of the following conditions are met the battery saver system is released and the steering will
change automatically to lock position from OFF position.
• Opening any door
• Operating with request switch on door lock
