General Description

Once IPM receives taillamp switch working signal, it sends the signal to RAM by CAN communition. RAM turns on the right taillamp.

DTC Description

This code is set when right taillamp circuit is open for more than 150ms during right taillamp operating.

DTC Detecting Condition

Item	Detecting Condition	Possible Cause
DTC Strategy	● Load Mornitoring	● Poor connection ● Open in right taillamp circuit ● Faulty right taillamp ● Faulty RAM
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.

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 RAM's connector or was repaired and RAM 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 Taillamp and License Marker Lamp

IG "OFF" and connect scantool

IG "ON" & ENG "OFF"

Select "Actuation Test" mode.

Execute "Taillamp and License Marker Lamp" test.

10.

Is Rear Fog Lamp 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 Taillamp Circuit Inspection" procedure.

Right Taillamp Circuit Inspection

■ Check open in harness

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

Disconnect RAM, right taillamp connector.

Measure resistance between the Right Taillamp terminal of RAM harness connector and ground of the Right 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 Right Headlamp High or Left Headlamp High internal open, 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.
