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
