Dealing with a check engine light can be frustrating and often expensive. Suddenly, that little light illuminates on your dashboard, and immediately thoughts of costly repairs and trips to the mechanic flood your mind. Many car owners have experienced the sting of hefty diagnostic fees at repair shops, often ranging from $60 to over $200 just to understand why that light is on. While some auto parts stores offer free diagnostic scans, the accuracy can be questionable, and the results might lead you down a path of unnecessary part replacements. For the DIY enthusiast, guessing and replacing parts hoping the check engine light disappears is a surefire way to waste both time and money. This is where a reliable OBD2 scanner becomes an indispensable tool. A quality scanner takes the guesswork out of the equation. It accurately identifies the reason behind the check engine light, displays the necessary diagnostic trouble codes (DTCs) to pinpoint the problem area, and even allows you to reset the light once the repair is completed.
In this review, we’re diving deep into the Innova 6100p Obd2 Scanner. I received this scanner for evaluation to provide an unbiased assessment of its capabilities. Currently priced at $138.99 on Amazon.com, the Innova 6100P aims to be a user-friendly yet powerful diagnostic tool for both seasoned mechanics and car owners alike. While my personal car collection leans towards the classics, predating onboard computers, I frequently assist friends and acquaintances with diagnosing issues on their modern vehicles (1996 and newer), which are predominantly OBDII compliant. Let’s explore if the Innova 6100P lives up to its promise as a valuable tool in the world of automotive diagnostics.
The Innova 6100P OBD2 scanner arrives in professional, sturdy packaging, complete with a dedicated carrying case. The scanner itself boasts a sleek and functional design. It features a generously sized, backlit monochrome screen that ensures excellent readability, even in brightly lit environments – a crucial factor when working outdoors or in a busy garage. Innova has equipped the 6100P with a high-quality OBDII cable, noticeably superior to many standard cables I’ve encountered. A thoughtful touch is the inclusion of optional battery power, which illuminates the OBDII plug itself. This seemingly small detail becomes incredibly helpful when you’re fumbling to connect the scanner in dimly lit conditions under the dashboard. The cable securely attaches to the scanner unit using captive screws, ensuring a robust connection during use.

Upon unboxing, I noticed a protective sticker applied to the screen of the Innova 6100P. Initially, it appeared to be a standard static-cling screen protector. However, upon peeling it off, it unfortunately left behind a sticky residue. After using the scanner a few times, I realized there was indeed an almost invisible protective layer beneath the sticker, which started to lift. Thankfully, the screen itself remained undamaged.
Somewhat surprisingly, the Innova 6100P does not come with a printed instruction manual. In today’s digital age, Innova directs users to online resources for the manual and operating instructions. While this might be perceived as a minor inconvenience for some, most users readily have access to smartphones or computers for online information.
Rather than immediately consulting the digital manual, I decided to put the Innova 6100P to a real-world test straight out of the box. I connected the scanner to a 2005 Jaguar XJ8 Vanden Plas to see how it would perform without prior instruction. If you are new to OBD2 scanners, it is advisable to read the instructions to familiarize yourself with the device’s functions.
As soon as the Innova 6100P was plugged into the Jaguar’s OBDII port, it automatically began the process of identifying the correct OBDII protocol for the vehicle. It then swiftly initiated a scan of the vehicle’s diagnostic system. In this particular instance, the scanner returned a P1111 code. The Innova 6100P utilizes a straightforward three-light system to visually communicate the severity of detected issues: Green indicates no problem, Yellow suggests a potential issue, and Red signifies a definite problem. This color-coded system provides an immediate and easily understandable indication of the diagnostic findings.
For many fault codes, the 6100P scanner aims to provide additional information about the code definition directly on the screen. However, in this case of the P1111 code, no further information was displayed. Having encountered the P1111 code before on Jaguars, I knew it typically indicates that the Jaguar Computer Assisted Technology (CAT) system has successfully cleared fault codes following a repair or system reset. Essentially, on a Jaguar, a P1111 code generally means “system pass” or “no faults present,” despite the scanner’s yellow “warning” light. This ambiguity can be slightly confusing for users who may not be familiar with Jaguar-specific codes.
My primary interest in testing the Innova 6100P stemmed from its advertised ability to access manufacturer-specific codes within systems like ABS (Anti-lock Braking System) and SRS (Supplemental Restraint System), as well as enhanced OBDII codes beyond the generic codes. The test Jaguar, with its history of intermittent transmission issues and occasional problems with its computer-controlled air suspension, seemed like an ideal candidate to explore these advanced capabilities. I was hoping the Innova 6100P could delve deeper into these systems and provide more specific insights into the root causes of these recurring issues. Unfortunately, Innova’s enhanced diagnostics feature supports a limited range of vehicle makes and models, and a 2005 Jaguar XJ8 is not among them.

Undeterred, I proceeded to test the Innova 6100P on a 2000 GMC Sierra work truck with considerable mileage. Given the truck’s somewhat rough running condition, I was confident it would reveal some diagnostic trouble codes. I connected the scanner and waited for it to complete its scan. The Innova 6100P performed its scan relatively quickly, taking approximately 25 seconds from start to finish.
To my surprise, the scan on the GMC Sierra returned no fault codes. Despite my expectation of uncovering at least one error code given the truck’s age and condition, all systems were reported as functioning within normal parameters.
The Innova 6100P also supports “Freeze Frame” data. Freeze Frame is a valuable feature that captures a snapshot of crucial engine parameters (like engine speed, temperature, fuel trim, etc.) at the precise moment a fault code is triggered. This information can be incredibly helpful in diagnosing intermittent issues or understanding the conditions under which a fault occurred. However, since neither of my test vehicles decided to cooperate by throwing any new codes during the testing period, I was unable to evaluate the Freeze Frame functionality firsthand.
Battery and alternator testing are often overlooked by home mechanics, typically until a no-start situation arises. The Innova 6100P includes a user-friendly feature to assess the overall health of the vehicle’s battery and charging system. The scanner provides clear, on-screen instructions for this test, which involves starting and stopping the engine three times. Both the Jaguar and the GMC Sierra passed this test, indicating a normal charging system status in both vehicles.
Another practical feature of the Innova 6100P is its ability to reset oil change lights, a particularly convenient function for those who perform their own oil changes. This eliminates the need for manual reset procedures, which can vary across different vehicle makes and models.
Navigating through the Innova 6100P’s menus allows users to examine a wide array of vehicle systems and monitors. The scanner successfully analyzed at least 12 different systems on the Jaguar and a similar number on the GMC pickup. This demonstrates a comprehensive scanning capability, even though deeper, manufacturer-specific diagnostics were not available for these particular vehicles. I was able to use the scanner to check the status of the oxygen sensors on the Jaguar, a component of concern due to the vehicle’s high mileage and age. Both oxygen sensor banks were reported as operating within their expected ranges.
What I Liked About the Innova 6100P:
- Excellent Carrying Case: The included hard-shell carrying case is a significant plus. It keeps the scanner, cable, and any accessories neatly organized and protected, preventing tangled cords and damage when stored in a trunk or toolbox.
- High-Quality, Long Cable: The OBDII cable provided with the Innova 6100P is exceptional. It feels robust and professionally made, and its generous length is a major advantage. I could comfortably operate the scanner while standing outside the passenger door of the Jaguar, even with the OBDII port located on the driver’s side.
- Bright and Clear Screen: The screen is a standout feature. It’s bright, sharp, and exceptionally easy to read under various lighting conditions. The font is clear and concise, and on-screen prompts guide you through the diagnostic process effectively.
- Solid Build Quality: The scanner itself feels well-constructed and durable, despite being relatively lightweight. The option to use batteries for standalone operation and the illuminated OBDII plug are thoughtful design elements.
- Responsive Rubberized Buttons: The buttons are made of rubberized material and offer good tactile feedback and responsiveness, even when wearing mechanic’s gloves.
Things I Don’t Like About the Innova 6100P:
- Unintuitive Button Labels: The button labeling is a weak point in the design. The use of abstract icons instead of clear text labels is confusing. While some icons are somewhat decipherable (like the “eraser” icon for the clear codes button), others are ambiguous and require referring to the manual. Acronyms like “M,” “FF,” and “DTC” might be recognizable to experienced users but are not self-explanatory for beginners. The lack of clear labeling diminishes the user-friendliness of the device. The manual also refers to “hot keys” during scanning without clearly indicating which buttons are designated as such, leading to some trial-and-error operation.
- No Live Data: A significant drawback of the Innova 6100P is its lack of live data streaming capability. Many users, especially experienced DIY mechanics, rely on live data to monitor real-time engine parameters and diagnose intermittent issues. The absence of this feature is a notable limitation compared to other scanners in a similar price range.
- Cumbersome Vehicle Information Entry: Manually entering vehicle information using the directional buttons is a slow and tedious process. A scanner that automatically decoded the Vehicle Identification Number (VIN) would significantly improve the user experience and speed up the diagnostic process. While holding the up or down buttons speeds up scrolling through menus, it still feels less efficient than a VIN auto-decode feature.
Things I Didn’t Know About Until Reading the Instructions:
- PC Connectivity and Software Updates: The Innova 6100P can connect to a computer via USB, allowing users to upload scan data and update the scanner’s firmware. Innova provides free software for this purpose, downloadable from their website. Regular firmware updates ensure compatibility with newer vehicles and the latest diagnostic codes, extending the scanner’s lifespan and value. The 6100P’s extensive system coverage, encompassing over 20 vehicle systems in modern cars, is also highlighted in the documentation.
- Redundant Button Functions and Learning Curve: As mentioned earlier, the button layout and labeling are not immediately intuitive. Due to the unclear functions of some buttons and overlapping functionalities, I found myself repeatedly scanning the same vehicle to ensure I was pressing the correct buttons to access the desired features. This points to a steeper initial learning curve than expected for a tool aimed at both professionals and home users.
Final Thoughts
I typically use a basic OBD2 scanner purchased online for around $40. It reads and clears codes, fulfilling fundamental diagnostic needs. The primary difference between my budget scanner and the Innova 6100P lies in the breadth of systems scanned. While my basic scanner provides limited fault code information, it does offer live data streaming, a feature absent in the Innova 6100P. Conversely, the Innova 6100P excels in its ability to access a wider range of vehicle systems and potential fault codes, going beyond the basic engine and emissions systems covered by cheaper scanners. The screen quality of the 6100P is significantly superior to my budget scanner, and I had hoped this would be coupled with live data capabilities for a more comprehensive diagnostic experience.
For home mechanics working on newer vehicles, the Innova 6100P offers a worthwhile upgrade over a basic, entry-level scanner. The expanded diagnostic capabilities and access to more detailed information related to fault codes justify the price difference, provided the enhanced features are compatible with your vehicle(s). The scanner’s robust build quality and updateable software suggest it’s a durable and long-lasting tool. The inclusion of a replacement cable option from Innova also addresses a common point of failure with many scanners – cable damage.
However, for those primarily working on older vehicles from the late 1990s and early 2000s, a more affordable, basic scanner might be a more practical investment, especially if live data is a priority. Modern vehicles are designed to capture and display more complex diagnostic data, making the advanced features of the Innova 6100P more relevant for newer models.
