Once IPM receives left headlamp high switch working signal, it sends the signal to FAM by CAN communition. FAM turns on left headlamp high.
This code is set when left headlamp high circuit is open for more than 150ms during left headlamp high operating.
Item | Detecting Condition | Possible Cause |
DTC Strategy | ● Load Mornitoring | ● Poor connection ● Open in left headlamp high circuit ● Faulty left headlamp high ● Faulty FAM |
Enable Conditions | ● IG KEY ON. | |
Threshold Value | ● It is normal if output voltage is 12V. | |
Diagnostic Time | ● Immediately | |
DTC Erasing Time | ● DTC is erased immediately after trouble fixed. |
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. |
IG "OFF" and Connect GDS.
IG "ON" & ENG "OFF"
Select "Current Data" mode.
Execute "left headlamp high" test.
Is left 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. |
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 "Left Headlamp High Circuit Inspection" procedure. |
IG "OFF", disconnect battery (-) terminal.
Disconnect FAM connector.
Measure resistance between the Left Headlamp High terminal of FAM harness connector and ground of the Left Headlamp High.
Specification: Approx. 1 Ω
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 open in circuit of Left Headlamp High or Left Headlamp High internal open, and go to "Verification of Vehicle Repair" procedure. |
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. |
