Run Fault: Shutdown
RUN I/O
Failed Off
Description
RPM Input Fault. The
Rear Door Protection
input stayed on when
the rear door reached
full open.
RPM Off with Rear
Gate Switch or Door
Lock On. The Rear
Door Protection
Module input must go
on before rear gate
switch or door lock
inputs go on.
Run Fault: Shutdown.
If the car attempts to
run 4 consecutive
times and incurs a
specific type of
emergency stop
without making a
successful run, the car
is shut down and this
error code is shown.
The specific types of
emergency stops to
cause this fault are as
follows: 1. The car
attempted to run and
the position counts
changed in the wrong
direction.2. The car
went on low oil while
running.3. The car
went on Hot Oil while
running.
The RUN input or

Section 6 – Main CPU Faults & Detailed Faults
Possible Cause/Suggested Fix
• RPM switch not setup properly on the door operator.
Faulty RPM input. Replace RPM input chip.
• The RPM switch on the door operator is not setup
properly.
• There is no RPM input on the door operator. Jump the
RPM input to the RGS terminal.
• Faulty RPM input. Replace the RPM input chip.
• Verify that the position counts change in the appropriate
direction while the car is running. A pulse direction fault will
also be recorded.• For a low oil condition, check the oil level
in the tank. Check the operation of the Low Oil Switch. A
low oil fault will also be recorded.• For Hot Oil, check the
operation of the TPH sensor and verify that the input is
working properly. A hot oil fault will also be recorded.
• The RUN relay failed to pick or the RUN relay contact has
failed to close. Replace the RUN relay.
• Faulty RUNi input. Replace the RUNi input chip.
• Faulty RUN output. Replace the RUN output chip.
• Voltage feed through one of the valve solenoids. Refer to
the schematic and check the circuit with a meter.
