Procedure

1. Chock wheels and engage the service brake.

WARNING
Crush Hazard. Because of the need to test
the throttle, the vehicle cannot be in complete
lockout/tagout. Be sure all non-operator
personnel are at least 20 feet (6 meters) away
from all areas of the vehicle. Failure to comply
may result in serious personal injury or death.
2. Check the functionality of the throttle.
• With the truck in neutral and the parking brake set, push the foot throttle to determine if the
engine revs up.
– If YES, proceed with loading the software (BCM) and then follow the steps outlined below.
– If NO, any throttle verification in the following steps will have to be verified while driving the
vehicle in gear. Proceed with loading the software (BCM) and then follow the steps outlined
below. Verification of the throttle functionality will come in later steps.
3. Load the software (BCM).
4. Flash the display.
5. Set the McNeilus parameters on display per the desired OEM configuration listed below (see
“Parameter and Wiring check per OEM Configuration” on page 4).
6. Set the speed limiter to Force ON (under software options 1).
7. Push the foot throttle with the engine running to determine if the throttle is disabled.

8. If the engine revs, the throttle is not disabled. Continue with the following checks until the throttle is
disabled. Once the throttle is disabled, the procedure continues at Step 9.
A. Check errors menu for active output under MCD3 Speed limiter
B. Visually verify wiring
1. Make sure the J10 wire (WHITE flying lead wire) in the cab harness is connected to position
7 of the ROPT170.
• Pin 3 on Mack diesel
2. If the speed limiter is not connected, verify in the OEM configurations below to determine if
you need a + or – signal.
• If the OEM requires a + signal, the only wiring requirement is to connect the J10 wire from
the cab harness to the ROPT170 position 7 (it is pin 3 on Mack diesel engine).
• If the OEM requires a – signal, locate MC250 near the BCM and swap J10+ & J10-.
– Move J10+ from pin 17 to pin 19 (MC250).
– Move J10- from pin 19 to pin 17 (MC250).
– Then connect the J10 wire to the ROPT170 position 7 (Mack diesel pin 3).
C. Use a multimeter to validate that the + or – signal (based on OEM requirements) is being
received to the ROPT170 connector.
D. Check OEM parameters per the desired OEM configuration listed below (see “Parameter and
Wiring check per OEM Configuration” on page 4).
9. Once the throttle has been verified to be disabled, with the speed limiter set to Force ON, set the
speed limiter to Disabled and once again use the foot throttle to check if the engine revs up.
• Special Note: On an Autocar chassis, if the engine does not rev up, then check for a jumper
labeled THROTTLE in the OEM harness.
– The jumper is located inside the left frame rail just below the fan shroud.
– The jumper is a 2-pin WeatherPack connector with a short ~4” wire going from pin A to pin B.
NOTE: There is a second jumper located directly next to the throttle jumper for the fan.
– Remove the wire from the jumper and reinstall the connector.
– Other chassis OEMs do not have this jumper issue.
10. Once the throttle has been verified to be inoperable with the speed limiter set to Force ON, and the
engine does indeed rev up when the speed limiter is set to Disabled, then set the Speed Limiter to
Enable.
Final Verification

WARNING
Crush Hazard. Be sure all non-operator
personnel are at least 20 feet (6 meters) away
from all areas of the vehicle. Failure to comply
may result in serious personal injury or death.
1. On the IFM display parameters, set “Arm Out Vhcl Spd Intrlck (MPH)” to 1mph.
2. Use the joystick to lower the grabber down to the bottom of the arm, open the grabber, and make
sure the arm is all the way in (home position/against body).
3. Start driving the vehicle above 1 mph to ensure the throttle is functional.

4. Stop the vehicle and use the joystick to close the grabber slightly to ensure the “grabber open”
proximity switch is not flagged.
5. With the grabber off the “grabber open” proximity switch, attempt to accelerate the vehicle. The
throttle should be disabled at any speed faster than 1 mph.
6. The throttle should also be disabled if the “arm in home” proximity switch is not flagged and the
vehicle speed is greater than 1 mph.
7. Push the E-STOP button and with the grabber still off the “grabber open” proximity switch, attempt
to accelerate the vehicle. The throttle should NOT be disabled at any speed.
8. Set “Arm Out Vhcl Spd Intrlck (MPH)” to desired customer value.

Special Notes

• The adapter harness part number 1545952 is used to connect the cab harness to OEM harness.
The large 31 pin connector is labeled ROPT1. The ROPT1 (McNeilus side) connects to the
ROPT170 (OEM side).
• When connecting the J10 wire to the adapter harness (part number 1545952), connect the J10
wire to the flying lead labeled 101 (WHITE wire). Verify that the 101 wire goes into position 7 of
the 31 pin connector.
