OBD2 scan tools were developed as a link between the driver and the ECU of their cars. Not all drivers are expert mechanics who understand code language. It is for this reason that the INNOVA 3140g was invented.
The INNOVA 3140g was designed to be a tool for both the professional mechanics and the regular DIYer. It is an incredible tool with many diagnostic features.

Detailed Review of INNOVA 3140g
Features and Functionality
The following are the features of the INNOVA 3140g:
One of the major functions of an OBD II scanning tool is to assess an Engine Check warning light.
The INNOVA 3140g is not an exception. It reads and interprets the Check Engine warning light of a vast variety of vehicles.
These include both domestic as well as foreign vehicles. The device also scans light trucks, SUVs, and even hybrid vehicles.
These are all vehicles manufactured after the year 1995.
Additionally, the INNOVA 3140g has an OBD 1 diagnostics kit to diagnose older vehicle models.
This kit only assesses popular vehicles manufactured from the year 1985 to 1996.
Vehicles on this range are popular Ford, GM, Chrysler, Lexus, Honda, and Toyota models.
Availability of the OBD 1 system increases the range of cars the device can access. The check engine light error code is interpreted in an easy to understand language.
This helps the common DIYer understand the faults with the engine.
The inclusion of the OBD 1 protocols increases the load on the CPU of the device. This could spell potential future malfunctions.
Additionally, the OBD 1 protocols are compatible with very few vehicles making this feature slightly irrelevant.
Live data stream
Live data means that the driver can assess the situation of the car as it runs. You connect the device and run the car to assess its parameters as it runs.
The device reads two different parameters at a go helping you monitor how one affects the other. It is a rare but important feature that the INNOVA 3140g has.
You can easily determine how one variable affects the other variable and form an opinion on what steps to take.
The data also fluctuates rapidly therefore reading could be a hassle. Even freezing the frame will require expert timing.
This could frustrate you because the playback cannot slow down.
ABS and SRS systems diagnostics
The INNOVA 3140g accurately reads and interprets the causes of ABS warning lights.
It is able to do this on all vehicles manufactured after 1996 that are compatible with the device.
These include vehicles from Ford, GM, Toyota, Chrysler, and Honda models. INNOVA 3140g reads these codes and erases them after the issue has been dealt with.
INNOVA 3140g is able to quickly detect the malfunction in both the ABS and the SRS systems. This puts the device above its competition.
The code is interpreted in language that is easy to understand. You can fix the error much faster with the help of the INNOVA 3140g.
SRS diagnostics are limited to very few vehicles. It is reported to not work on a number of vehicles.
The INNOVA 3140g is compatible with all OBD II protocols.
This makes the device compatible with most vehicles produced during and after the year 1996. The device works on ordinary cars, SUVs, light trucks and even hybrids.
INNOVA 3140g works on most vehicles with a battery capacity of 12V.
The scan tool also contains OBD 1 compatibility that connects to popular vehicles from Chrysler, Ford, GM, Toyota, Lexus, and Honda.
The limitation of OBD1 functions is very high. It is important for the buyer to be careful when purchasing this device for OBD 1 functions.
Some customers complain that it does not work on their cars manufactured before 1996.
One customer said that the device did not work on a 1994 Chevrolet Camaro Z, 28.

Who is it for?
The device was created for both expert mechanics and regular DIYers.
It has expansive functions that are suitable for a mechanic. The INNOVA 3140g reads and interprets DTCs in plain language making it suitable for the regular DIYer.
The Bottom Line
INNOVA 3140g was developed for common DIYers as well as professional mechanics. However, this device seems more suited for a regular DIYer than a professional mechanic. This is because it lacks the professional tools that a mechanic needs from such a device.
