STEP 10. Check ETACS-ECU connectors C-311 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connectors C-311 in good condition?
YES : Go to Step 11.
NO : Repair the damaged parts.
STEP 11. Check the wiring harness between rear side
marker light (RH) F-10 connector (terminal No. 2) and
ETACS-ECU connector C-311 (terminal No. 13).
Check the communication line for open or short circuit.
NOTE: Before the wiring harness check, check the F-15, F-18
and repair that if necessary.
Q: Is the wiring harness between rear side marker light
(RH) F-10 connector (terminal No. 2) and ETACS-ECU
connector C-311 (terminal No. 13) in good condition?
YES : Go to Step 12.
NO : Repair the wiring harness.
STEP 12. Check rear combination light (RH) connector
D-09 for loose, corroded or damaged terminals, or
terminals pushed back in the connector.
Q: Is combination light (RH) connector D-09 in good
condition?
YES : Go to Step 13.
NO : Repair the damaged parts.
STEP 13. Resistance measurement at rear combination
light (RH) connector D-09.
(1) Disconnect the connector, and measure at the wiring
harness side.
(2) Measure the resistance between rear combination light
(RH) connector D-09 (terminal No. 4) and the body ground.
The measured value should be continuity exists (2
Ω or less).
Q: Does the measured resistance value correspond with
this range?
YES : Go to Step 15.
NO : Go to Step 14.
