Step Check
Remedy
Yes No
Possible causative parts:
SENSOR HUM (PL8.1.10)
PWBA MCU (PL8.3.6)
HARNESS ASSY L SIDE MG AIO (PL3.1.18)
1
Does the error still occur when the power is turned OFF and
ON?
Go to step 2. End of work.
2
Checking after resetting the SENSOR HUM.
Reseat the SENSOR HUM.
Does the error still occur when the power is turned OFF and
ON?
Go to step 3. End of work.
3
Checking the HARNESS ASSY L SIDE MG AIO for
continuity.
Disconnect J20 from the PWBA MCU.
Disconnect J201 from the SENSOR HUM.
Is each cable of J20 <=> J201 continuous?
Go to step 4.
Replace the
HARNESS ASSY
L SIDE MG AIO.
4
Checking the power to SENSOR HUM.
Disconnect the connector of J20 from the PWBA MCU.
Is the voltage across P20-4pin <=> ground on the PWBA
MCU, about +5 VDC?
Replace the
SENSOR HUM.
(Refer to REP8.6.)
Replace the KIT
PWBA MCU.
(Refer to
REP8.10.)
