Sliding Door Encoder System Inspection

1. Turn ignition switch OFF.
2. Check voltage between sliding door control unit connector B60 (LH) or B143 (RH) terminal 11 and ground.

   11 - Ground : Approx. 9V

OK or NG 

OK: GO TO 3.

NG: GO TO 2.

Check continuity between sliding door control unit connector B60 (LH) or B143 (RH) terminal 22 and ground.

22 - Ground : Continuity should exist  .

OK or NG 

OK: GO TO 4.

NG: Replace sliding door control unit.

Operate the sliding door and check voltage waveform between sliding door control unit connector B60 (LH) or B143 (RH) terminals 4, 17 and ground using an oscilloscope.

4 - Ground 17 - Ground
