System Components

Technical makeup of the GRIP Idle Management System


The GRIP Controller is the “brain” of the system. It receives data from the vehicle through the CAN (Controlled Area Network) as well as each of the additional sensors added within the system. The controller receives information on engine revolutions, transmission status, battery voltage, coolant temperature, engine hours, interior and exterior climate, and hood position. It takes all of this information and decides when the vehicle can be shut down to avoid idle, or when the vehicle needs to be running to meet the criteria set in the program or operator input.

Idle Reduction System GRIP Screen


The Screen is the interface between the operator and the controller. The Screen will display the status of the vehicle and indicate to the operator when a change is going to to take place. The operator will use the screen to set the desired temperature within the cab as well as access other options within the system, if so equipped. The screen is only accessible when the vehicle is in park or neutral, making it a hands-free device.

Hood Pin

The Hood Pin is a magnetic sensing safety feature used during vehicle servicing. The hood pin needs to make contact with a magnet that’s installed on the hood, for the GRIP System to control the vehicle. This contact is essential, as it allows for servicing with the hood up without the GRIP starting the engine. At this point, the vehicle can only be started manually with a key. For additional safety, an icon appears on the screen when the hood is up.

Idle Reduction Technology GRIP Temperature Sensor

Temperature Sensor

The Temperature Sensor transmits the temperature of the cabin to the GRIP System’s Controller. This sensor is positioned in the vehicle to obtain an optimal reading to ensure climate accuracy.


The Anti-Theft feature allows the operator to leave the vehicle secured with keys in-hand while the GRIP System continues to monitor and control the vehicle. Only the operator returning with the keys can disable Anti-Theft mode.

Idle Reduction System GRIP External Coolant Heater

External Coolant Heater

The External Coolant Heater is a fuel-fired heater added to the vehicle’s coolant system that heats the coolant to operating temperature without running the engine, and will also run the coolant pump as needed. The External Coolant Heater can be programmed and scheduled as required, or based on specific conditions.


The Solenoid latches the primary and auxiliary batteries. When the voltage in the primary battery reaches a lower threshold, a signal is sent from the controller to the solenoid to latch to the auxiliary battery. When the vehicle is running, the Solenoid also latches to charge both batteries simultaneously. This function allows for extended shut-down periods while maintaining the performance of electronics, auxiliary components, and the vehicles ability to start.

Idle Reduction System Auxiliary Battery

Auxiliary Battery

An Auxiliary Battery allows for more extended periods of shutdown while maintaining electronic and auxiliary functions, acting as a reservoir to the primary battery. The Auxiliary Battery is attached to the Primary Battery through the use of a solenoid.

Current Sensor

A Current Sensor ensures that applications that require high current receive the current needed by communicating to the GRIP Controller and powering the vehicle accordingly.

Idle Reduction System GRIIP Coolant Pump

Coolant Pump

An External Coolant Pump keeps already-warm coolant flowing through the vehicle’s heat exchanger, allowing the vehicle’s cabin to retain heat and warmth without running the engine. This extended cabin warmth, in turn, allows the engine to shut down for more extended periods.

Heater Remote Start

Remote control allows the operator to start the external coolant heater or vehicle engine from outside the vehicle.

Idle Reduction System GRIP Alarm

Audible Alarm

An Alarm provides an audible alert to let the operator know when the vehicle is going to start up or shut down.
