B20E3 LED HEADLAMP LH

DTC Description

INFOID:0000000010452564

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector
• Front combination lamp LH internal circuit
- LED [Headlamp (LO)]
- LED headlamp control module
- Harness
• IPDM E/R

FAIL-SAFE

Transmits the headlamp warning signal (CAN communication) to the combination meter when the headlamp
(LO) ON conditions are satisfied. (When the ignition switch turns ON, the headlamp warning is displayed on
the information display of the combination meter.)

DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

DTC B20D0.
Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to 

EXL-97, "DTC Description"

.

NO

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1.

Turn ignition switch ON.

2.

Turn lighting switch 2ND and wait at least 2 seconds or more.
