Front Door Switch LH Circuit InspectionEIS0 02 ZA
1. CHECK FUNCTION
With CONSULT-II
Touch "BCM" with “DOOR SW DR” on the DATA MONITOR, check
ON/OFF operation when the front door is open and closed.
*:Refer to SE-40, "DATA MONITOR" .
Without CONSULT-II
GO TO 2.
OK or NG
OK >> Front door switch LH circuit is OK.
NG >> GO TO 2.
2. CHECK FRONT DOOR SWITCH LH
1. Turn ignition switch OFF.
2. Disconnect front door switch.
3. Check continuity between front door switch LH terminal 2 and ground.
OK or NG
OK >> GO TO 3.
NG >> Replace front door switch LH.
3. CHECK HARNESS CONTINUITY
1. Disconnect BCM.
2. Check continuity between BCM connector M19 terminal 47 and
front door switch LH connector B8 terminal 2.
3. Check continuity between BCM connector M19 terminal 47 and
ground.
OK or NG
OK >> Front door switch LH circuit is OK.
NG >> Repair or replace harness.

UART Communication Line Circuit InspectionEIS002ZB
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.

4. CHECK DRIVER SEAT CONTROL UNIT
Does the automatic drive positioner operate when the driver seat control unit is exchanged?
OK or NG
OK >> Replace driver seat control unit.
NG >> Replace automatic drive positioner control unit.1 (L) - 10 (L) : Continuity should exist.
17 (W) - 26 (W) : Continuity should exist.
