< BASIC INSPECTION >
[POWER DISTRIBUTION SYSTEM]
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.
2.
Perform the following procedure if DTC is displayed.
-
Record DTC and freeze frame data.
-
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 relationship 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 relationship 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
PCS-38, "DTC Inspection Priority Chart"
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 Confirma-
tion Procedure.
Is DTC detected?
YES
>> GO TO 8
NO
>> Refer to
GI-51, "Intermittent Incident"
.
6.
PERFORM BASIC INSPECTION
Perform
Inspection End>>GO TO 7
7.
DETECT MALFUNCTIONING SYSTEM BY SYMPTOM TABLE
Detect malfunctioning system according to
based on the confirmed symptom in
step 4, and determine the trouble diagnosis order based on possible causes and symptom.
>> GO TO 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 CONSULT-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 replace-
ment.
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 fully repaired.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4 and check that
the symptom is not detected.
OK or NG
NG (DTC is detected)>>GO TO 8
NG (Symptom remains)>>GO TO 6
OK

FUNCTION DIAGNOSIS
POWER DISTRIBUTION SYSTEM
System Description
INFOID:0000000001712706
INPUT/OUTPUT SIGNAL CHART
SYSTEM DESCRIPTION
• PDS (POWER DISTRIBUTION SYSTEM) is the system that BCM controls with the operation of the ignition
switch and performs the power distribution to each power circuit.
• If equipped with Intelligent Key, the ignition switch can be operated when Intelligent Key is in the detection
area of the interior antenna.
• The ignition switch operation is input to BCM as a signal. BCM changes the power supply position according
to the status and operates the ignition relay (inside IPDM E/R) to supply power to each power circuit.
