B20D5 TAIL LAMP RH POWER SUPPLY CIRCUIT

B20D5 TAIL LAMP RH POWER SUPPLY CIRCUIT

DTC Description

INFOID:0000000010469960

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector
• Rear combination lamp RH (body side) internal circuit
- LED (Tail lamp)
- Harness
• Rear combination lamp RH (back door side) internal circuit
- LED (tail lamp)
- Harness
• IPDM E/R

FAIL-SAFE

Shuts off the power supply to the following power supply circuits until the parking lamp, license plate lamp, and
tail lamp ON conditions are no longer satisfied.
• Tail lamp RH (body side)
• Tail lamp RH (back door side)

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

With CONSULT

1.

Turn ignition switch ON.

2.

Select “T LAMP 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 tail lamp RH (body side) or tail lamp RH (back door

side) power supply circuit, and damage 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 

EXL-271, "Diagnosis Procedure"

 and replace IPDM E/R after the malfunc-

tioning part is repaired. Refer to 

PCS-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 1ST.

4.

Select “Self Diagnostic Result” mode of “IPDM E/R” using CONSULT.

5.

Check DTC.

Is DTC detected?

YES

>> Refer to 

EXL-271, "Diagnosis Procedure"

.

DTC No.

Diagnosis Procedure

INFOID:0000000010469961

1.

CHECK TAIL LAMP RH POWER SUPPLY CIRCUIT (SHORT)

1.

Turn ignition switch OFF.

2.

Turn lighting switch OFF.

3.

Disconnect the following connectors.

-

IPDM E/R

-

Stop lamp / tail lamp RH (body side)

-

Tail lamp RH (back door side)

4.

Check continuity between IPDM E/R harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace harness.

2.

CHECK TAIL LAMP RH POWER SUPPLY

With CONSULT

1.

Connect IPDM E/R connector.

2.

Turn ignition switch ON

3.

Select “TAIL LAMP” in “Active Test” mode of “IPDM E/R” using CONSULT.

4.

With operating the test items, check the voltage between stop lamp / tail lamp (body side) harness con-
nector 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 TAIL LAMP RH

Check the tail lamp RH. Refer to 

EXL-271, "Component Inspection"

.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Repair or replace the malfunctioning part.

Component Inspection

INFOID:0000000010469962

1.

CHECK TAIL LAMP RH

1.

Turn ignition switch OFF.

2.

Disconnect stop lamp / tail lamp RH (body side) and tail lamp RH (back door side) connector.

3.

Check resistance of stop lamp / tail lamp RH (body side) and tail lamp RH (back door side) terminals.
