PCS-10, "Diagnosis Description"

 (with Intelligent Key) or 

PCS-

41, "Diagnosis Description"

 (without Intelligent Key).

2.

Check that the headlamp switches to the high beam.

CONSULT ACTIVE TEST

1.

Select “EXTERNAL LAMPS” of IPDM E/R active test item.

2.

With operating the test items, check that the headlamp (HI) is turned ON.

NOTE:
ON/OFF is repeated 1 second each.

Is the headlamp (HI) turned ON?

YES

>> Headlamp (HI) circuit is normal.

NO

>> Refer to 

EXL-42, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009945141

1.

CHECK HEADLAMP (HI) OUTPUT VOLTAGE
