Diagnostic Circuit Diagram
Scantool Data Analysis
1.

Connect GDS.

2.

IG "ON" and engine "OFF".

3.

Select "DTC Analysis" mode.

4.

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

5.

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 rear left turn signal lamp
6.

IG "OFF" and connect scantool

7.

IG "ON" & ENG "OFF"

8.

Select "Actuation Test" mode.

9.

Execute "rear left turn signal lamp" test.

10.

Is the service data 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
1.

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.

2.

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

3.

Has a problem been found?

▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.

▶ Go to "Rear Left Turn Signal Lamp Circuit Inspection" procedure.

Rear Left Turn Signal Lamp Circuit Inspection
■ Check short to ground in harness
1.

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

2.

Disconnect RAM, Rear Left Turn Signal Lamp connector.

3.

Measure resistance between the rear left turn signal lamp terminal of RAM harness connector and chassis ground.

Specification: infinity

4.

Is the measured resistance within specification?

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

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

▶ Repair short to ground in circuit of Rear Left Turn Signal Lamp, 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.

1.

Connect scan tool and select "DTC Analysis" mode.

2.

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

3.

Is any DTC outputted again?
