FIP1.44 SENSOR FACE UP OPEN
Step Check
Yes
No
Possible causes:
SENSOR FACE UP OPEN (PL10.1.25)
GATE FU (PL10.2.6)
LEVER GATE FU (PL10.2.17)
HARNESS ASSY EXIT SNR (PL10.1.27)
HVPS/MCU (PL12.1.19)
1
Checking GATE FU for operation
Open COVER ASSY REAR 500.
Move LEVER GATE FU up and down.
Does GATE FU operate smoothly?
Does the actuator go into the sensor detecting point
when LEVER GATE FU is moved up, and out of the
detecting point when down?
With tool Go to
step 2. Without

Go to step 3.
3
Checking HARNESS ASSY EXIT SNR for continuity
Remove 500 EXIT ASSY (PL10.1.2) (RRP10.2)
Remove HARNESS ASSY EXIT SNR.
Is there continuity between
J29-4 and J291-3?
J29-5 and J291-2?
J29-6 and J291-1?
Go to step 4.
Replace HAR-
NESS ASSY EXIT
SNR.
