ames near the battery. Never lay objects on the battery that can short the terminals together. If battery
acid gets in your eyes, immediately seek rst aid. If acid gets on your skin, immediately wash it off with
soap and water.
3.2 Getting Started
This manual provides instructions for installing the InPower Model ITM150 Interlock System in the RAM Promas-
ter vans with gasoline engines and with a FMVSS compliant, public use (commercial) platform lift. It is important
that you follow these instructions carefully and contact InPower if you need assistance or more information.
Note that product technical documents are available on InPower’s web site.
This interlock system installation requires additional parts and materials that are not supplied with the interlock
product. Identify all required parts before starting the installation and ensure that these items are the correct
type and quality.
Inspect the interlock product and all other components for damage before starting the installation. Do not per-
form the installation if any problems exist.
Determine the type of interlock interface required for the platform lift. This interlock system provides a +12 volt
@ 1.8 amps Enable Lift output to allow the platform lift to be operated. If the lift system is not compatible with
this interface signal you must take the necessary actions to adapt the lift system interface to the interlock sys-
tem’s interface. Refer to the lift manufacturer’s installation instructions for further details.
The recommended mounting location for the ITM150 interlock control module is in the center console below the
shifter, due to the proximity of the wiring connections. The unit must not be located in the engine compart-
ment or any location that is not protected from the environment.

5. Wiring Instructions (cont.)
Circuit 4 Wiring (Platform Lift)
Review the platform lift installation manual and determine how to wire the ITM150 interlock system to
the platform lift’s interlock interface. Note that the Enable Lift is a +12 volt OUTPUT from the interlock
system and an INPUT to the lift system. When at +12 volts the platform lift can be operated.
Connect the interlock yellow Enable wire found on the interlock harness to the lift enable input.
Note: The ITM150 interlock will supply a +12 volt @ 1.8 amp output to allow operation of the lift. Verify that this
is the correct polarity for the platform lift.
The following diagrams show the wiring interface of typical platform lift systems. Be sure to verify the exact wir-
ing interface for the lift system that you have.
Final Steps
Once the harness is completely wired, mount the module and plug in the harness. Test to ensure that it has
been wired correctly and that there are no loose connections.

6. Interlock System Operation
The interlock system is powered when the Ignition Switch is on. The following is the interlock system sequence
of operation:
Step 1 - Ignition switch on and engine running.
Step 2 - Press service brake and place shifter in Park.
Step 3 - Set parking brake.
• Shift Lock will activate
Step 4 - Open lift door.
• Lift Enable will activate allowing operation of platform lift.
Step 5 - The platform lift may now be operated (Refer to the platform lift operating instructions).
Note: During the Lift Enable sequence, if the parking brake is released the Lift Enable
will be deactivated, preventing lift operation.
Step 6 - When the lift cycle is completed, return the lift to its fully stowed position.
Step 7 - Close the lift door.
Step 8 - Release parking brake. When released, the shift lock will be automatically released.
Step 9 - The cycle is now complete and the vehicle can be taken out of Park and driven.
7. System Troubleshooting
If there is a problem with system operation, there is a very high probability that either the control module lost its
ground or +12 volt power source, or that one or more of its inputs are not being activated by the remote switches
(e.g., Lift Door Switch). Most troubles are related to wiring problems, or switches either failing or becoming out
of adjustment.
Troubleshooting Procedure:
Step 1: Determine if the control module is powered. If the LEDs on the controle module are illuminated, you
have power. If none are illuminated, check that all connectors are rmly in place and the shifter sensor is
properly positioned. Also ensure that the 10 pin connector is properly connected to the shifter and that the 7.5
amp fuse F16 in the Power Distribution Center is functioning.
Step 2: If the connectors and fuses are all correct, rst reset the interlock system by turning off its power. Then,
step through the operating sequence described in Section 6. Pay particular attention to the diagnostic LEDs on
the module. Verify that the LEDs agree with the switch position. If they do not, check the corresponding wiring
and the sensor position.
The ITM150 module contains six diagnostic LED indicators to aid in system troubleshooting. These show the
status of input and output signals of the control module.
System Diagnostic LED Indicators (Located on the controle module)
POWER ◙ (Red) On when +12 volt power is applied to module. The LED will go out if the EN
ABLE output current exceeds 2 amps
PK BRK ◙ (Red) On when the park brake is set.
PARK ◙ (Red) On when the transmission is in the Park position
ENABL ◙ (Red) On when the interlock allows the platform lift to operate.
DR OPEN ◙ (Red) On when the platform lift door is ajar or open (not fully closed)
