My Review: Innova 5610 Scan Tool

Innova 5610 Review: The Best DIY Scan Tool with Pro Features

If you’re serious about fixing your own car, you must have a scan tool. Modern vehicles are rolling computers. You can’t even replace brake pads on many newer models without one. Innova provided their #5610 CarScan Pro and CarScan Mobile for my review. Here’s why I think you should own the 5610. It provides professional-level diagnostics without the professional-level price.

Why Investing in a High-Quality Scan Tool Makes Sense

Auto parts stores offer free code scans for only one reason: to sell whatever part(s) are listed in the trouble code, whether it’s the cause of the code or not. Replacing whatever part is listed in the trouble code, without doing any other diagnostic work, is the #1 cause of repair failures. A trouble code is not a diagnosis; it’s just a starting point. It’s up to you to conduct further testing to identify the root cause of the issue in the code. Replacing parts without conducting further testing (firing the parts cannon) wastes time and money. How many times have you heard someone say, “I replaced the part, but the check engine light is still on”? If a professional mechanic operated that way, you’d be furious. Yet, DIYers often fall into this trap.

Smart DIYers Always Invest in The Right Tools

Think $350 is steep for a scan tool? Back in the 1960s, every serious DIYer owned a timing light, a tachometer/dwell meter, and a vacuum gauge. A serious amateur tach/dwell meter cost around $30 in the 60’s, equivalent to $330–$350 in today’s dollars. A timing light would set you back another $15–$20, or roughly $150–$170 today. In other words, in today’s dollars, every DIY spent the equivalent of at least $330-$480 on specialty tools. Today’s cars don’t require a tach/dwell meter or a timing light, but they do require a high-quality scan tool to diagnose issues that may arise.

Here’s What Makes the Innova 5610 So Powerful

It reads Global (Generic) and Enhanced Trouble Codes

Most inexpensive code readers only retrieve global (generic) codes. A Global code, as the name implies, means the same thing for all carmakers. However, enhanced trouble codes (P1xxx, U1xxx, etc.) and their definitions are manufacturer-specific and go beyond the OBD-II standard.

Here’s an example: A P1450 on a Ford refers to “Unable to Bleed Up Fuel Tank Vacuum,” but that code may not exist on other brands. Enhanced codes may cover: Advanced transmission faults, Manufacturer-specific emissions controls, Body and chassis electronics, HVAC systems, and Advanced driver assistance systems (ADAS).

• The Innova 5610 reads all Global codes and Enhanced codes for the vehicles specified at the bottom of this article.
• The Innova 5610 Provides Live Data — Why You Need It To Diagnose Trouble Codes

Let’s say you pull up a P0420 trouble code indicating a catalytic converter with low efficiency. The converter is an expensive part. Before replacing it, you’d want to rule out other possible causes, such as an air leak, exhaust leak, fuel pressure issue, or issues with the upstream or downstream oxygen sensors. That’s where you use live data.

In this example of a P0420, you’d start by checking out short and long-term fuel trims:

Short-Term Fuel Trim (STFT) and Long-Term Fuel Trim (LTFT)
STFT and LTFT tell you whether the engine control module (ECM) is adding or subtracting fuel to maintain the ideal air-fuel ratio. An LTFT above 10% can be due to low fuel pressure, clogged fuel injectors, a vacuum leak, exhaust leak, a carboned throttle body, or an air duct leak. In the case of a P0420, we see that the long-term fuel trims are not out of spec.

Next, You’d Check Oxygen Sensor Voltages (O2 Sensors) and Switch Rates
The ECM utilizes the upstream oxygen sensor (O2) to monitor the effectiveness of air-fuel mixture regulation, while the downstream O2 sensor assesses the performance of the catalytic converter.

A properly operating upstream O2 varies widely and rapidly, while the downstream O2 would normally be in the middle range and steady. By viewing the O2 sensor’s live data and switch rates, you can determine if the sensors are operating properly.

In this case, we’re seeing a normal upstream oxygen sensor reading, with rapidly changing values. We’re also seeing a fairly flat downstream graph, without the wide fluctuations shown in the upstream sensor.

The combination of a low LTFT, a varying upstream O2 trace, and a flat downstream O3 trace rules out a vacuum or exhaust leak. Either leak would result in a high LTFT and possibly a flatter upstream trace.

What we’re seeing is a converter that has lost efficiency due to physical damage, or clogging/melting caused by an internal oil or coolant leak, or ignition misfires.

Before I replace the converter, I want to check for misfires, even though I don’t have a misfire code. That’s where Mode $06 comes in handy.

How Mode $06 Helps Your Diagnostics

OBDII Mode $06: Mode $06 is one of the most important diagnostic tools professionals use. Advanced users and pros mainly use it to spot marginal components that haven’t yet triggered a DTC but are performing poorly.
The test items are identified by Parameter IDs (PIDs) or Test IDs (TIDs) and Component IDs (CIDs).

PID/TID Type Typical Component/Monitor Purpose
TID $01-$05 Oxygen Sensor Tests Response times, switching performance
TID $06-$0A Catalyst Efficiency Monitors the catalyst (converter) oxygen storage capability
TID $0B-$10 EGR System Performance Flow rates and malfunction detection
TID $11-$20 Evaporative Emission System Leak detection and purge valve operation
TID $21-$30 Secondary Air System Air pump and valve monitoring
TID $31-$40 Heated Oxygen Sensor Heater Circuit Heater circuit resistance and current draw
TID $41-$50 Misfire Detection (for specific cylinders) Counts and thresholds for cylinder misfires
TID $51-$60 Thermostat Monitoring Open/close performance
TID $61-$70 Transmission Monitors (on some vehicles) Clutch, shift solenoid tests

Test ID (TID) Identifies the type of test (e.g., O2 sensor response time)
Component ID (CID) / MID Identifies the component (e.g., Bank 1 Sensor 1 O2 sensor)
Min Limit The minimum acceptable value for this test
Max Limit The maximum acceptable value for this test
Value (Measured) The actual test result from the vehicle
Pass/Fail Whether the component passed or failed the test

Example: O2 Sensor Test
Test: O2 Sensor Rich to Lean switch time
Limits: 20 ms (min), 100 ms (max)
Measured: 95 ms
Status: PASS, but close to failing.
This sensor is functioning properly, but its response time may increase slightly as it ages. I’d watch this component closely.

In the case of the P0420, I use Mode $06 to check these PIDs, checking for values that are close to setting a trouble code.

TID $01-$05 Oxygen Sensor Tests Response times, switching performance
TID $41-$50 Misfire Detection (for specific cylinders) Counts and thresholds for cylinder misfires
TID $31-$40 Heated Oxygen Sensor Heater Circuit Heater circuit resistance and current draw

Use the 5610 to Check Out Other Live Data

In addition to all the above sensors,

This image shows just some of the many live data options available

live data gives you important information on

•Engine RPM and vehicle speed
•Engine Coolant Temperature and intake air temperature
•Ignition timing,
•Variable valve timing: Phaser advance/retard and solenoid pulse width
• Throttle Position Sensor
•Transmission input/output shaft RPM and shift solenoid operation,
•Transmission fluid temperature that affects transmission shifting
•Fuel pressure and Fuel injector pulse width
•EGR operation
•Evaporative Emissions data
•Radiator fan operation
•Throttle and Accelerator Pedal Position Intake Air Temperature (IAT)
•Knock sensor values
•Crankshaft and camshaft position sensor data

The Innova 5610 Allows You To Conduct Relearn/Reset Procedures.

Throttle body cleaned? Battery replaced? New brake pads installed? The 5610 lets you perform relearns and resets like a pro, including:
•Throttle body relearn
• Oil change light reset
• Steering angle calibration
• Battery initialization/registration
• ABS brake bleed
• Electronic Parking Brake Reset
• Diesel Particulate Filter Reset.

The Innova 5610 Allows You to Conduct Bidirectional Testing

Many DIY enthusiasts don’t understand the importance of this feature. Let’s say you have a P0441 Evaporative Emission Control System Incorrect Purge Flow code. To operate the purge valve to check for operation, as well as for sticking and clogging.

Without a bi-directional testing feature, you’d have to use power and ground jumper wires to actuate the valve to view the port. However, with the Innova 5610, all you need to do is follow the EVAP testing procedure for your vehicle. The 5610 sends a command to the ECM, telling it to open/close the purge valve. No jumper wires are needed.

The Innova 5610 Includes Battery and Charging System Tests

Check your battery’s health and alternator charging voltage to catch problems before they leave you stranded.

The Innova 5610 Gives You Access to Freeze Frame Data

Freeze frame data captures a snapshot of key sensor readings and operating conditions at the exact moment a fault code (DTC) is set. This data typically includes engine RPM, vehicle speed, coolant temperature, fuel trim, throttle position, and other vital parameters. By reviewing freeze frame data, you can see what was happening when the problem occurred, helping them diagnose the root cause more accurately. It’s like looking at a “crime scene photo” that shows the system’s state at the time of failure.

Read the Readiness Monitors Before Going For a Smog Check

This vehicle is ready to go for emissions testing

I/M readiness monitors are built-in self-diagnostic checks in a vehicle’s onboard computer system (OBD-II) that track the performance of key emissions-related components. “I/M” stands for Inspection and Maintenance, and these monitors help determine whether your vehicle’s emission systems are functioning properly. There are two types: continuous monitors (like misfire and fuel system checks) that are always active, and non-continuous monitors (like the catalyst or EVAP system) that require specific driving conditions to complete. All required monitors must show as “ready” for a vehicle to pass an emissions test. How it’s used: This feature is critical before taking your car for an emissions inspection—know it will pass before you go.

The Innova 5610 Includes Other Professional Diagnostic Modes

OBDII Mode $05: Provides actual raw data from O2 sensor monitor tests
OBDII Mode $08: Provides actual raw data from EVAP emissions related systems

The Innova 5610 Gives You Access to Technical Service Bulletins

Carmakers publish service bulletins to their dealers when they make a change to a commonly failing part, modify fluid or maintenance requirements, or update software. Professionals usually refer to service bulletins before starting their diagnosis. Why try to diagnose a problem that the carmaker has already identified as a pattern failure, or a failure where there’s a software fix?

The Innova 5610 puts those service bulletins and your finger tips, breaking them down by category.

My Overall Review of the Innova 5610

I like this tool a lot. It’s the closest you’re going to get to a professional grade scan tool without spending thousands. With the code scanning, live data, access to service bulletins, and RepairSolutions2 database, you can diagnose and fix most issues.

The user interface is easy to navigate and the unit has a powerful processor, so new screens upload quickly. I add that because I’ve used other scan tools in this price range and they’re not fast. I’ve tested some scan tools that took almost 15 seconds to change screens. That’s especially frustrating if you’re moving back and forth between screens. Thankfully, it’s not an issue on the 5610.

In addition to the 5610 CarScan Pro, I also used the CarScan Mobile. I downloaded the app, plugged in the dongle and then paired the dongle to my phone using Bluetooth.

I highly recommend the CarScanPro to any serious DIYer looking for a scan tool that offers professional features at an affordable price.

I want to thank Innova for giving me the chance to test out the 5610. Now, I’m seriously thinking about selling my expensive OTC scan tool.
