General Description

Once IPM receives right headlamp high switch working signal, it sends the signal to FAM by CAN communition. FAM turns on right headlamp high.

DTC Description

This code is set when right headlamp high circuit is shotted to ground for more than 150ms during right headlamp high operating.

DTC Detecting Condition

Item	Detecting Condition	Possible Cause
DTC Strategy	● Load Mornitoring	● Poor connection ● Short to ground in right headlamp high circuit ● Faulty right headlamp high ● Faulty FAM
Enable Conditions	● IG KEY ON.
Threshold Value	● It is abnormal if output voltage is 0V.
Diagnostic Time	● Immediately
DTC Erasing Time	● DTC is erased immediately after trouble fixed.

Diagnostic Circuit Diagram

Scantool Data Analysis

Connect GDS.

IG "ON" and engine "OFF".

Select "DTC Analysis" mode.

After erase DTC, keep the vehicle condition within "the enable conditions" (Refer to "DTC Detecting Condition" table).

Is the same DTC occurred again?

	▶ Go to next procedure.
	▶ Fault is intermittent caused by poor contact in the sensor's and/or FAM's connector or was repaired and FAM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.

■ Check right headlamp high

IG "OFF" and Connect GDS.

IG "ON" & ENG "OFF"

Select "Current Data" mode.

Execute "right headlamp high" test.

10.

Is right headlamp high working normal ?

	▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Go to next procedure.

Terminal and Connector Inspection

Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Has a problem been found?

	▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Right Headlamp High Circuit Inspection" procedure.

Right Headlamp High Circuit Inspection

■ Check short to ground in harness

IG "OFF", disconnect battery (-) terminal.

Disconnect FAM, Right Headlamp High connector.

Measure resistance between the Right Headlamp High terminal of FAM harness connector and chassis ground.

Specification: infinity

Is the measured resistance within specification?

▶ Substitute with a known - good FAM and check for proper operation.

If the problem is corrected, replace the FAM and go to "Verification of Vehicle Repair" procedure.

▶ Repair short to ground in circuit of Right Headlamp High, and go to "Verification of Vehicle Repair" procedure.

Verification of Vehicle Repair

After a repair, it is essential to verify that the fault has been corrected.

Connect scan tool and select "DTC Analysis" mode.

Clear the DTCs and Operate the vehicle within DTC Enable conditions in General information.

Is any DTC outputted again?

	▶ Go to the applicable troubleshooting procedure.
	▶ System performing to specification at this time.
