Troubleshooting
SENSOR HUM
HARNESS ASSY HUM
PWBA OHP SNR
HARNESS ASSY OHP SNR
HARNESS ASSY OHP
PWBA MCU
Step
Check
Yes
No
1
Check after turning the power OFF and ON
Does the error recur even when the power is
turned off and back on again?
Go to Step [2].
End of procedure
2
Check the connection of the PWBA OHP
SNR
Check the connection state between PWBA
OHP SNR and PWBA MCU.
Are P/J2411, P/J241, and P/J24 connected
correctly?
Go to Step [3].
Reconnect
P/J2411, P/J241,
and P/J24
correctly.
3
Check the continuity of the HARNESS ASSY
OHP SNR
Is the continuity between P/J2411 <=> P/J241
normal?
Go to Step [4].
Replace the
HARNESS
ASSY OHP SNR.
4
Check the continuity of the HARNESS ASSY
OHP
Is the continuity between P/J241 <=> P/J24?
Go to Step [5].
Replace the
HARNESS
ASSY OHP.
5
Replace of the PWBA OHP SNR
Replace the PWBA OHP SNR.
Was the trouble fixed?
End of procedure Go to Step [6].
6
Replace of the PWBA MCU
Replace the PWBA MCU.
Was the trouble fixed?
End of procedure Go to Step [7].
7
Check the connection of the SENSOR HUM
Check the connection state between SENSOR
HUM and PWBA MCU.
Are P/J261 and P/J26 connected correctly?
Go to Step [8].
Reconnect P/J261
and P/J26
correctly.
Step
Check
Yes
No
8
Check the continuity of the HARNESS ASSY
HUM
Is the continuity between P/J261 <=> P/J26
normal?
Go to Step [9].
Replace the
HARNESS
ASSY HUM.
9
Check the power voltage supply to SENSOR
HUM.
Measure the voltage between PWBA MCU
ground <=> P/J26-4PIN.
Is the power voltage (approx. +5 V) output?
Replace the
SENSOR HUM.
Replace the
PWBA MCU.
