Innova 3140g: ABS SRS OBD1/OBD2 Diagnostic Tool Review

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:

MIL diagnostics

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.

Strength:

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.

Weakness:

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.

Strengths

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.

Weaknesses

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.

The device also performs accurate scans of SRS systems for limited OBD II compatible vehicles.

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.
