OK or NG
1. OK: Encoder SW circuit is OK
2. NG: GO TO 2.
CHECK HARNESS CONTINUITY
1. Turn ignition switch OFF.
2. Disconnect power window sub-switch (rear LH or RH) and power window motor (rear LH or RH).
3. Check continuity between power window sub-switch (rear LH or RH) connector D55 (LH), D75 (RH) terminal 19 and power window motor (rear LH or RH) connector D52 (LH), D72 (RH) terminal 5.
  19 (G/Y) - 5 (G/Y): Continuity should exist.
OK or NG
1. OK: GO TO 3.
2. NG: Repair or replace harness.
