Lancer Sportback L4-2.4L (4B12) (2010)
STEP 3. Resistance measurement at rear combination light connector F-20 (taillight: LH) or F-06 (taillight: RH), rear side marker light
connector F-40 (LH) or F-35 (RH)).
1. Disconnect the connector, and measure at the wiring harness side.
2. Measure the resistance between the connector of light which does not illuminate and the body ground.
-
Measure the resistance between rear combination light connector F-20 (taillight: LH) or F-06 (taillight: RH) (terminal 3) and body ground.
-
Measure the resistance between rear side marker light connector F-40 (LH) or F-35 (RH) (terminal 1) and body ground.
OK: The measured value should be continuity exists (2 ohms or less).
Q: Does the measured resistance value correspond with this range?
YES : Go to Step 5.
NO : Go to Step 4.
STEP 4. Check the wiring harness between rear combination light connector or rear side marker light connector and the body ground.
Check the ground line for open circuit.
-
Check the wiring harness between rear combination light connector F-20 (taillight: LH) (terminal 3) and the body ground.
-
Check the wiring harness between rear combination light connector F-06 (taillight: RH) (terminal 3) and the body ground.
-
Check the wiring harness between rear side marker light connector F-40 (LH) (terminal 1) and the body ground.
-
Check the wiring harness between rear side marker light connector F-35 (RH) (terminal 1) and the body ground.
Q: Is the wiring harness between rear combination light connector or rear side marker light connector and the body ground in good condition?
YES : Go to Step 7.
NO : Repair the wiring harness.
STEP 5. Check ETACS-ECU connector C-311 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
Q: Is ETACS-ECU connector C-311 in good condition?
YES : Go to Step 6.
NO : Repair the damaged parts.
