UART Communication Line Circuit InspectionEIS004YM
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 wave form does not appear with a constant voltage (approx. 5V), replace driver
seat control unit.
When voltage wave form does not appear with a constant voltage (approx. 0V), replace auto-
matic driver seat control unit.
2. CHECK UART LINE INPUT/OUTPUT SIGNAL 2
Check signal between automatic drive positioner control unit con-
nector ground, with oscilloscope.
OK or NG
OK >> GO TO 3.
NG >> Check the following.
When voltage wave form does not appear with a constant voltage (approx. 5V), replace auto-
matic drive positioner control unit.
When voltage wave form does not appear with a constant voltage (approx. 0V), replace driver
seat control unit.

3. CHECK UART LINE HARNESS
1. Disconnect driver seat control unit and automatic drive posi-
tioner control unit.
2. Check continuity between driver seat control unit connector P2
terminals 1, 17, and automatic drive positioner connector M33
terminals 10, 26.
3. Check continuity between driver seat control unit connector P2
terminals 1, 17 and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair or replace harness.
4. CHECK DRIVER SEAT CONTROL UNIT
