CHUTE ASSY-REAR SWITCH-PH DOOR
HARNESS-ASSY P/H1 HARNESS-ASSY P/H2
PWBA MCU HARNESS ASSY MAIN
LV/HVPS
Step Check Yes No
1
Shape check of CHUTE ASSY-REAR
Is the actuator of CHUTE ASSY-REAR that
presses SWITCH I/L CAB (P/H Cover
Switch) damaged?
Replace
CHUTE ASSY-
REAR. (p.325)
Go to Step [2].
2
Operation check of SWITCH-PH DOOR
Disconnect the P/J408 from the PWBA MCU.
Is there continuity on J408-5 ↔ J408-6 when
SWITCH-I/L CAB is pressed, and does the
continuity stop when the switch is released?
Go to Step [5]. Go to Step [3].
3
Continuity check of HARNESS-ASSY P/H1
Disconnect the P/J408 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J408-5 ↔ J603-8
J408-6 ↔ J603-7
Go to Step [4]. Replace
HARNESS-
ASSY P/H1.
Actuator
4
Continuity check of HARNESS-ASSY P/H2
Disconnect P/J603.
Do all of the wiring below have normal
continuity?
P603-5 ↔ J100-2
P603-6 ↔ J100-1
Replace
SWITCH-PH
DOOR. (p.339)
Replace
HARNESS-
ASSY P/H2.
5
Power supply check to PWBA MCU
Is the specified DC voltage being supplied to
the following terminals on PWBA MCU?
P410-1 ↔ P410-2: 3. 3 VDC
P410-3 ↔ P410-4: 5 VDC
P410-5/6 ↔ P410-7/8: 24 VDC
Replace PWBA
MCU. (p.404)
Go to Step [6].
6
Continuity check of HARNESS ASSY MAIN
Disconnect P/J410 from PWBA MCU and P/
J502 from LV/HVPS.
Do all of the wiring below have normal
continuity?
J410-1 ↔ J502-1
J410-2 ↔ J502-2
J410-3 ↔ J502-3
J410-4 ↔ J502-4
J410-5 ↔ J502-5
J410-6 ↔ J502-6
J410-7 ↔ J502-7
J410-8 ↔ J502-8
Replace LV/
HVPS. (p.407)
Repair broken
or shorted part.
Step Check Yes No
