CHUTE ASSY-FSR SWITCH 2BTR COVER
HARNESS ASSY ADC HARNESS ASSY 2BTR SW
PWBA MCU LV/HVPS
Step Check Yes No
1
Shape check of CHUTE ASSY-FSR
Is the actuator of CHUTE ASSY-FSR that
presses SWITCH 2BTR COVER damaged?
Replace
CHUTE ASSY-
FSR. (p.341)
Go to Step [2].
2
Operation check of SWITCH 2BTR COVER
Disconnect the P/J418 from PWBA MCU.
Is there continuity on J418-7 ↔ J418-8 when
SWITCH 2BTR COVER 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 ADC
Disconnect the P/J418 from the PWBA MCU.
Do all of the wiring below have normal
continuity?
J418-7 ↔ J621-2
J418-8 ↔ J621-1
Go to Step [4]. Replace
HARNESS
ASSY ADC.
Actuator
4
Continuity check of HARNESS ASSY
2BTR SW
Disconnect the P/J418 from the PWBA MCU.
Do all of the wiring below have normal
continuity?
P621-1 ↔ J113-2
P621-2 ↔ J113-1
Replace
SWITCH 2BTR
COVER.
(p.352)
Replace
HARNESS
ASSY 2BTR
SW.
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
