Step
Check
Yes
No
1
Check the connection of the PWBA OHP
LED and the PWBA OHP SENSOR
Check the connection state of the following items.
PWBA OHP LED - PWBA MCU
PWBA OHP SENSOR - PWBA MCU
Are P/J2411, P/J2412, P/J241, and P/J24
connected correctly?
Go to Step [2].
Reconnect
P/J2411, P/J2412,
P/J241, and P/J24
correctly.
2
Check the continuity of the HARNESS ASSY
OHP SNR
Is the continuity between P/J2412 <=> P/J241
normal?
Go to Step [3].
Replace the
HARNESS
ASSY OHP SNR.
3
Check the continuity of the HARNESS ASSY
OHP
Is the continuity between P/J241 <=> P/J24
normal?
Go to Step [4].
Replace the
HARNESS
ASSY OHP.
4
Check the power voltage supply to PWBA
OHP LED
Measure the voltage between PWBA MCU
ground <=> P/J24-1PIN.
Is the power voltage (approx. +3.3 V) output?
Go to Step [5].
Replace the
PWBA MCU.
5
Replace of the PWBA OHP LED
Replace the PWBA OHP LED.
Was the trouble fixed?
End of procedure Go to Step [6].
6
Check the continuity of the HARNESS ASSY
OHP SNR
Is the continuity between P/J2411 <=> P/J241
normal?
Go to Step [7].
Replace the
HARNESS
ASSY OHP SNR.
7
Check the continuity of the HARNESS ASSY
OHP
Is the continuity between P/J241 <=> P/J24
normal?
Replace the
PWBA OHP
SENSOR.
Replace the
HARNESS
ASSY OHP.
Step
Check
Yes
No
