1. 

CHECK UART LINE INPUT/OUTPUT SIGNAL 1

1.

Turn ignition switch OFF.

2.

Check signal between driver seat control unit connector and
ground, with oscilloscope.

OK or NG

OK

>> GO TO 2.

NG

>> Check the following.

●

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

●

When voltage waveform does not appear with a constant voltage (approx. 0V), replace auto-
matic driver seat control unit.

2.

Check signal between automatic driver positioner control unit con-
nector ground, with oscilloscope.

OK or NG

OK

>> GO TO 3.

NG

>> Check the following.

●

When voltage waveform does not appear with a constant voltage (approx. 5V), replace auto-

CHECK UART LINE HERNESS

1.

Disconnect driver seat control unit connector and automatic
drive positioner control unit connector.

2.

Check continuity between driver seat control unit connector
B303 terminal 1 (Y/W), 17 (Y/L) and automatic drive positioner
connector M19 terminal 10 (R), 26 (R/G).

3.
