connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. Verify that 
the front park lamp (LH) illuminates normally.

STEP 22. Check the wiring harness between front 
combination lamp (LH) connector A-20 (terminal 2) and 
front-ECU connector A-11X (terminal 4).
Q: Is the wiring harness between front combination lamp 

(LH) connector A-20 (terminal 2) and front-ECU 
connector A-11X (terminal 4) in good condition?
YES : No action is necessary and testing is complete.
NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. Verify that 
the front park lamp (LH) illuminates normally.
