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 DTC INSPECTION PRIORITY CHART, and determine trouble diag-
nosis 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-41, "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.
7.
DETECT MALFUNCTIONING PART BY DIAGNOSIS PROCEDURE
EXL-244
< BASIC INSPECTION >
[HALOGEN HEADLAMP]
DIAGNOSIS AND REPAIR WORK FLOW
Inspect according to Diagnosis Procedure of the system.
Is malfunctioning part detected?
YES
>> GO TO 8.
NO
>> Check according to
GI-41, "Intermittent Incident"
.
8.
REPAIR OR REPLACE THE MALFUNCTIONING PART
1.
Repair or replace the malfunctioning part.
2.
Reconnect parts or connectors disconnected during Diagnosis 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 again, and then check that the
malfunction is repaired securely.
When symptom is described by the customer, refer to confirmed symptom in step 3 or 4, and check that the
symptom is not detected.
Is DTC detected and does symptom remain?
YES-1 >> DTC is detected: GO TO 7.
YES-2 >> Symptom remains: GO TO 4.
NO
>> Before returning the vehicle to the customer, always erase DTC.

B20CF HEADLAMP (HI) RH POWER SUPPLY CIRCUIT
B20CF HEADLAMP (HI) RH POWER SUPPLY CIRCUIT
DTC Description
INFOID:0000000010469944
DTC DETECTION LOGIC
POSSIBLE CAUSE
• Harness or connector
• Headlamp (HI) RH bulb
• Headlamp (HI) RH bulb socket
• IPDM E/R
FAIL-SAFE
Shuts off the power supply to the headlamp (HI) RH power supply circuit until the headlamp (HI) ON conditions
are no longer satisfied.
DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
With CONSULT
1.
Turn ignition switch ON.
2.
Select “HL (HI) RH CIRC MALFUNCTN” in “Data Monitor” mode of “IPDM E/R” using CONSULT.
3.
Check the monitor status.
What is the monitor status?
“0”
>> GO TO 2.
“1”
>> A short circuit is detected multiple times in the headlamp (HI) RH power supply circuit, and dam-
age accumulates at the smart FET inside the IPDM E/R. For this reason, IPDM E/R does not turn
ON the smart FET. Because the DTC cannot be reproduced in this state, perform
and replace IPDM E/R after the malfunctioning part is repaired. Refer to
67, "Removal and Installation"
.
2.
PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
1.
Turn ignition switch OFF.
2.
Turn ignition switch ON.
3.
Turn lighting switch 2ND, and lighting switch HI.
4.
Select “Self Diagnostic Result” mode of “IPDM E/R” using CONSULT.
5.
Check DTC.
Is DTC detected?
YES
>> Refer to
EXL-256, "Diagnosis Procedure"
.
NO-1
>> To check malfunction symptom before repair: Refer to
GI-41, "Intermittent Incident"
.
NO-2
>> Confirmation after repair: INSPECTION END
Diagnosis Procedure
INFOID:0000000010469945
1.
CHECK HEADLAMP (HI) RH POWER SUPPLY CIRCUIT (SHORT)
1.
Turn ignition switch OFF.
2.
Turn lighting switch OFF.
DTC No.

2.
CHECK HEADLAMP (HI) RH POWER SUPPLY
With CONSULT
1.
Connect IPDM E/R connector.
2.
Turn ignition switch ON
3.
Select “HEADLAMP (HI)” in “Active Test” mode of “IPDM E/R” using CONSULT.
4.
With operating the test items, check the voltage between front combination lamp RH harness connector
and ground.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Replace IPDM E/R. Refer to
PCS-67, "Removal and Installation"
.
3.
CHECK HEADLAMP (HI) RH
Check the headlamp (HI) RH. Refer to
EXL-257, "Component Inspection"
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Repair or replace the malfunctioning part.
