3. CHECK HARNESS CONTINUITY
1. Disconnect driver seat control unit connector.
2. Check continuity between driver seat control unit connector
B152 terminals 23 (Y/W), 36 (Y/G) and "memory switch and
lumber support switch" connector D3 terminals 23 (Y/W), 36 (Y/
G).
3. Check continuity between driver seat control unit connector
B152 terminals 23 (Y/W), 36 (Y/G) and ground.
OK or NG
OK >> GO TO 5.
NG >> Repair or replace harness between automatic drive positioned control unit and "memory switch
and lumber support switch".

2. CHECK UART LINE SIGNAL 1
1. Turn ignition switch ON.
2. Check signal between driver seat control unit connector ground,
with oscilloscope.
OK or NG
OK >> GO TO 3.
NG >> Check the flowing.

When voltage waveform dose not appear with a constant voltage (approx. 5V), replace driver
seat control unit.

When voltage waveform dose not appear with a constant voltage (approx. 0V), replace auto-
matic drive positioner control unit.
3. CHECK UART LINE SIGNAL 2
Check signal between automatic driver positioner control unit con-
nector ground, with oscilloscope.
OK or NG
OK >> GO TO 4.
NG >> Check the flowing.

When voltage waveform dose not appear with a constant voltage (approx. 5V), replace auto-
matic driver seat control unit.

When voltage waveform dose not appear with a constant voltage (approx. 0V), replace driver
seat control unit.
4. CHECK DRIVER SEAT CONTROL UNIT
Dose the automatic drive positioner operate, when the driver control unit exchanged?
Does seat memory function operate?
YES >> Replace automatic drive positioner control unit.
NG >> Replace driver seat control unit.
