Step
Check
Yes
No
1
Check of dirt and foreign bodies on surface
of SENSOR ASSY ADC
Are there any dirt or foreign bodies on the
SENSOR ASSY ADC surface?
Clean to remove
any dirt or
foreign bodies,
and go to step
[2].
Go to Step [2].
2
Check of SENSOR ASSY ADC attachment
Is SENSOR ASSY ADC attached correctly?
Go to Step [4].
Re-attach, and go
to step [3].
3
Does the error recur when the power is
turned ON?
Go to Step [4].
End of procedure
4
5 VDC and 24 VDC power supply check to
SENSOR ASSY ADC
The voltage of P422-2
↔
P422-4 on PWBA
MCU is 24 VDC?
And the voltage of P422-8
↔
P422-4 is 5
VDC?
Go to Step [5].
Go to Step [7].
5
Continuity check of HARNESS ASSY ADC
Disconnect P/J422 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J422-8
↔
J431-1
J422-4
↔
J431-5
J422-2
↔
J431-7
Go to Step [6].
Replace
HARNESS
ASSY ADC.
6
Check after replacement of SENSOR ASSY
ADC
Replace SENSOR ASSY ADC.
Does the error recur when the power is turned
ON?
Go to Step [7].
End of procedure
7
Power supply check to PWBA MCU
Are each of the power voltages being supplied
to the following terminals on PWBA MCU
from LV/HVPS?
P410-1
↔
P410-2: 3. 3 VDC
P410-3
↔
P410-4: 5 VDC
P410-5/6
↔
P410-7/8: 24 VDC
Replace PWBA
MCU.
Go to Step [8].
8
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.
Repair broken or
shorted part.
