Features and functionality
1. OBD1 and OBD2 parameters and functions
The gadget provides live data in addition to a standardized series of diagnostic trouble codes (DTCs), which provide for quick identification and rectification of malfunctions within the vehicle.
The Innova 3120 obd1 scan tool identifies problematic codes and provides the option to clear them. Some of the error codes are the cause of transmission or emission failures.
It can request for and clear emission-related diagnostic trouble codes that may occur during a driving cycle.
Other than reading powertrain and vehicle information, this scanner can read and erase current, pending, and permanent error codes.
The Innova 3120 obd1 scan tool has a battery and oil reset function. You can accurately read the battery’s power and check the oil.
2. Supported languages
When the scan tool has given the diagnostic trouble code definition, it can be displayed in English, French, or Spanish.
3. On-screen icons
The G and M icons on the screen help indicate whether the code set is either a generic specific code (G) or a manufacturer specific code (M).
The car and computer icons show whether the scanner communicates appropriately with the car and PC, respectively.
Numerous emission icons are also situated under an I/M monitor status title. They indicate whether your vehicle’s emission monitors are functioning as required or not.
4. Keys
On this tool’s keypad, there is a button labeled FF. When you press this button, the tool will display Freeze Frame data.
The red button on the left turns off the check engine light (MIL) function.
The green button on the right is used to signal the tool to begin communicating with the vehicle.
5. Light Indicators
Another unique patented feature of the Innova 3120 is the three-color emission status warning lights. These lights indicate how your vehicle will perform in emission or smog tests.
Green means pass, yellow means there could be potential problems, and red means you will undoubtedly fail an emission test. Over 30 states in the US now use an OBDII-based system to check for emissions readiness.

It works perfectly for a wide variety of vehicles. Only one device is needed for the different cars. A client mentioned in a review that it works exceptionally well on his two cars and those of his relatives. The cars they had were a 2000 Dakota, 2 Dodge Rams (1995 and 2005), and his step son’s 1998 Durango.
Another customer also tried the Innova 3120 obd1 scan tool on a 1995 Ford. When the check engine light turned on, he ran a scan using this tool, but it didn’t bring up any fix codes for the check engine light. Instead, a 111 “all systems functioning normally” notification kept popping up.
