Make: Thomas Built Buses
Model: Minotour
Production Dates: Begin: 01/23/2008 End: 06/04/2020
Descriptive Information: Certain Minotour School buses built on a GM chassis with an optional wheelchair lift
Number potentially involved: 615 Estimated percentage of involve with defect: 100%
Defect / Noncompliance Description
For this Defect/Noncompliance:
Describe the defect or noncompliance: On the affected Minotour vehicles, the driver may be able to release the park brake and shift the transmission out of Park and into a drive gear while the wheelchair lift is deployed.
Describe the safety risk: The potential for the vehicle to have forward or rearward mobility while the wheelchair lift is deployed may increase the risk of injury.
Identify any warning which can precede or occur: N/A

Component Name: N/A
Component Description: N/A
Component Part Number: N/A
Chronology of Defect / Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the noncompliance decision: In mid-August 2020, Thomas Built Buses received a report from the field indicating that a Minotour bus could be moved while with wheelchair lift door was open and the wheelchair lift was completely stowed. A review was conducted of the functionality on 2 Minotour buses with different activation options using the NHTSA FMVSS 403/404 test procedures as a basis for examining whether the system complies, and no fault was found at the time. The functionality of the two different Minotour lift activation systems, while apparently meeting the requirements of FMVSS, were not identical. TBB Engineering started a project to review the lift activation systems and make modifications in order to provide consistency in the product options. At the end of August 2020 a potential product improvement was reviewed for functionality. Engineering began the work required to release the new design into production. In September 2020, TBB Engineering questioned the initial observations made in August. October 2020, another review was conducted on a Minotour bus. A discrepancy was identified in the operation observed in August and that observed in October. TBB Engineering began an in depth review of the wiring systems on both of the buses that were reviewed. On November 3, 2020, DTNA determined that a non-compliance to FMVSS 404 may exist on certain Thomas Built Buses Minotour vehicles.
Identify the Remedy
Describe the defect/noncompliance remedy program, including the manufacture’s plan for reimbursement. The wheelchair lift wiring will be modified as needed. Repairs will be performed by Daimler Trucks North America authorized service facilities. Copies of the reimbursement plan will be submitted as a supplemental report when available.

The letter notifying vehicle owners is included for your reference.
Please note that the National Traffic and Motor Vehicle Safety Act, as amended (Title 49, United States Code,
Chapter 301), requires the owner’s vehicle(s) be corrected within a reasonable time after parts are available to you. The
Act states that failure to repair a vehicle within 60 days after tender for repair shall be prima facie evidence of an
unreasonable time. However, circumstances of a particular situation may reduce the 60 day period. Failure to repair a
vehicle within a reasonable time can result in either the obligation to (a) replace the vehicle with an identical or
reasonably equivalent vehicle, without charge, or (b) refund the purchase price in full, less a reasonable allowance for
depreciation. The Act further prohibits dealers from selling a vehicle unless all outstanding recalls are performed.
Any lessor is required to send a copy of the recall notification to the lessee within 10 days. Any subsequent stage
manufacturer is required to forward this notice to its distributors and retail outlets within five working days.

Remove Existing Wheelchair Lift Harness and Replace
with New Harness P/N 227436
Start
Vehicle Preparation
Turn vehicle/engine
OFF, place in Park,
chock wheels, and
turn the Body Circuit
breaker to the OFF
position.
Step 2
Prop and secure the
compartment door to the
full open position to gain
front access into the
electrical compartment,
as shown in Fig. 2.
Is vehicle fully
disabled and
secured?
YES
NO
Step 1
Remove the fasteners
holding the head bump
pad, and compartment
metal side cover, and lay
them to the side. This
provides side access into
the electrical
compartment. See Fig. 1.
Figure 1
Gain access to
the harness
by following
steps 1–3.
See Fig. 1.
Figure 2
Step 3
Remove fasteners that
anchor the printed circuit
boards mounting plate to the
compartment floor, and
ROTATE the entire assembly
to gain access to the wheelchair
lift harness. See Fig. 3.
Figure 3
Start of the harness removal
and installation.
The connector disconnect
sequence shown may be changed
to suit your preference.
Step 4
The replacement harness is similar
to the existing harness making it
a near one for one replacement.
Prior to removing the existing
harness, it is recommended to label
and take photos of the connection
points to aid with this installation.
Step 5
Disconnect connector
P11 from PCB 2. To aid
in identification, this is
a six pin connector with
two wires.
Step 6
On the same breakout
(run) as P11,
disconnect the male/
female Spade
Terminal (red wire).

Step 7
Staying on PCB 2,
disconnect connector P20
from PCB 2. This a six pin
connector with two wires
(red wire and a black wire).
Step 8
Go to PCB 1 and
disconnect connector P17.
P17 is a six pin connector
with two wires (a red wire
and a white with black
stripe wire).
Step 9
Staying on the same end
of harness, disconnect
connector PL27. PL27 is a
four pin connector
populated with four wires
(red, black, white, and
green wires).
This completes both
PCB connector
removals.
Proceed to next step .
Step 10
Disconnect LIFT
connector. LIFT connector
is three pin populated with
three wires (green with
white stripe, yellow, and
green wires). It is in the
general proximity to PL27.
Step 11
Remove the screws
holding the relay pack/
housing to the PCB
mounting plate.
Step 12
Disconnect connector
CL23 . This is a six pin
connector with six wires
(black, black, white with
black stripe, black, white,
green).
Step 13
Ensure all other harness
fasteners have been
removed, such as plastic
cable ties, and REMOVE
HARNESS FROM VEHICLE.
Prior to installing the new
harness (P/N: 227436),
perform one last visual
inspection of the harness for
evidence of any
imperfections, to ensure all
the connectors are in place,
not damaged, and all the
wires are seated fully in each
connector cavity.
Start of New Harness
Installation
BEST PRACTICE
When installing this harness,
provide adequate strain relief for
each connector/connection. DO
NOT pull any wires tight at the
connectors during installation as
this may lead to premature
failure.
