Testing:

To ensure the Idleright Fuel Management System is functioning properly, it is important to test the system
periodically. While the initial programming is suitable for most gasoline vehicles, there are other factors
that could lead to system failures. For instance, an aged vehicle, with an old worn battery and an inefficient
warning light system will require a higher detection voltage and longer runtime than a brand new vehicle
with an LED warning system. Other factors like climate should also be taken into consideration. For example,
colder climates may require higher detection voltage and longer crank time than warmer climates. Since the
Idleright Fuel Management System does not measure outside temperature, it is important to do testing to
ensure the system will operate properly in the field if any of these conditions have changed since the vehicle
was first placed into service.

In order to test the Idleright unit, turn on the lightbar and ensuring the vehicle starts when battery voltage
is low. Note that the vehicle should be outdoors or in a well-ventilated area during testing. Adjust the
programming as needed for optimal performance. If technical issues are encountered, please contact your
installer for assistance.

System Diagnostics:

In the event of a fault or system failure, the LED indicator will flash as follows:

Rapid On/Off Flashing – Over Current Detected. The Idleright System has detected an over current

•

condition. All outputs have been shut down to prevent damage to the system.
Slow On/Off Flashing – Failed to Start. The Idleright System has attempted to start the vehicle 3 times

•

and failed. Common causes of this are a weak vehicle battery or electrical system, a Voltage trip point
set too low or Initial Crank Time set too low.
