This Scan Tool is great, cleared the codes on my 2001 VX Commodore. Can do heaps of other stuff as well. Would recommend.
28 March 2024
I was in need of a scan tool to diagnose two VS Holden commodores. The scan tool delivered clear and accurate valuable information, Simple and straight forward to use and operate. On both vehicles I was able to get to bottom of both engine and airbag issues. Being able to print the displayed information was a big plus for me. The cost of this scan tool is reasonable when considering its capability. Other makes and models are covered through the purchase of additional soft ware, this can get expensive if you are trying to cover a large range of vehicles. Overall a great product.

Excellent product does everything it was discribed to do and more I recommend the i400au scan tool if you own a Holden best money I ever invested
19 January 2024
These are a great little scan tool lots of features for the price. I already have one and have added 5 more car makes to it and also used a 32gb micro sd card. The only problem i have had with it which i contacted Vident is that on Holden VE>2009>Service>Adaptions>Fuel Trim Reset is that i get a can bus off error the Stability ESP off light comes on the dash, it will sometimes take 9 minutes to enter Fuel Trim Reset which the Trim percentages say -2600% and -34% i dont know if this is a scan tool software compaitibility issue or something else, i have a hikeit throttle controller attached ( dont know if thats interferring ) when i scan for codes i get a can bus off in ECBM, other than that it works perfect, would recommend to anyone looking for a full function scan tool for a cheap price, its a great starting point for car enthusiant but who i am to say im getting a collection of scan tools now. I still give this scan tool apart from the problem it has with my car 5 stars. Keep up the good work AZ Scanners.

Very good unit, reads my VS ute and has good live data reading. Good communication from the seller also.
6 December 2023
I have recently purchased a Vident i400 for use on a VX commodore. I wasn't sure just how reliable this unit would be with the earlier Holden protocols, but I was actually pleasantly surprised. It connects quickly, it uses the now standard diagnostic protocol's and works through each page quickly, so far I have not suffered a complete lock up which I frequently experience on other brands of scanner on European vehicles, so I am very happy with the product and personally I feel it is good quality, very well priced.
24 November 2023
Best investment I've made Easy operation Easily diagnose problems Light weight Quality construction
13 November 2023
Bought this it does what it’s meant too, added another 4 car makes and a 32gb sd card. Still like Autel better though. Undecided whether to keep this or move it on. It’s good value for money and a great starting point for a DIY Mechanic. The add on car makes are $60 USD on the Vident account, so a little pricey. Hope this review helps someone decide on this scan tool. Great communication from AZ Scanners too.
13 November 2023
Came preinstalled with Holden software and easily connected to a VT Commodore. The i400 is a good diagnostic tool with many features including testing fuel injectors, various solenoids, and relays. I read the fault codes easily and cleared them. I also ran the various test to check if all the components are functioning normally. I then re-linked the ecu with the PCM and the VT is now more responsive and so far it has not stalled while being driven or while idling.
9 October 2023
Good service from Gary at AZ . The tool does all its reported to do. Excellent communication plus a You Tube channel that offers introductions and advise.
18 September 2023
Bought scanner as mechanic couldn't find what was causing a shudder that recently developed in my car. Plugged scanner in and found issue straight away. Problem is fixed and never relying on mechanic again.
11 September 2023
This Vident i400 AUOBD ALDL scan tool for my Holden was that good I bought one for Brother inlaw for his Holden. I was able to find out my problem with my car, took it to get fixed before other problems occurred.
4 September 2023
Great machine I have a few issues which I will make contact to the team which I won't post here due the possibility of user error. The delivery was ultra quick and well protected from Australia Post

Great scanner,has paid for its self already,clearing 4 different codes on 3 model Holdens,well worth the money
31 July 2023
I feel it's a good scanner for the price it found the problem with the srs airbag and and cleared code's I'm not sure if it can do as much as it says it can but for the price I'm pleased with it. Maybe a bit over priced for a single make scanner
28 July 2023
Excellent service from Gary and the team at AZ scanners. Competitive pricing , Great back up on Product information and Software updates, Recommended
2 July 2023
The tool works fine for my vx commodore (2001) for removing the airbag fault code light on the dash.. although if you don't fix the error that you see on the scan tool,it does come back on...scan to clear again...also changed my wheel hubs now ABS is on doesn't support this code.. maybe it needs to be upgraded or I'm not using it correctly so it's probably paid for itself as I have removed the airbag light fault code 4 or 5 times now was no problem before I changed the damaged clockspring after following all the protocols so bought the tool hoping that I don't have to go to the stealership or my local mechanic who sees me as a money pit or is it time to upgrade The car..
20 June 2023 Response
Hi Jeff, If the scanners are capable of clearing codes but the code comes back up this means that the sensor is reporting the fault again so the repairs were not completed as supposed. Please address this on your end. There is also lots of good info on about some repair situations.
Vident i400au with holden program so far so good does what it said it will do. Saves me time with finding error code
6 June 2023
found two codes that were coming up quickly easy to use
5 June 2023
Very happy with it
23 May 2023
This actually worked for vt v6 commodore and it work Very well!
8 May 2023
First tool ive ever had that has connected to a VR commodore It has not dissapointed at all
1 May 2023
Delivery was extremely quick and the tool does exactly what it's meant to do. The software updating process is very easy and the software interface that you download onto your computer is very good as it shows you the current price of additional car makes and allows you to add them on easily.
24 April 2023
Was amazed at how comprehensive this little scanner is. Not only does it have excellent scan functions but also links BCM / PCM / KEYS plus many other functions. Have used many scan tools,some megabuck units. Bought to access pre 2005 Commodores & extremely happy with its performance. A bit clunky as have to select each item from scan selection & press F3 key to get readout & then back out & go again on next item, but a minor issue when considering the price & it's ability to perform. Great value for money.
23 February 2023
A great scanner for beginners like me. My auto electrician mate has the same unit. Very easy to navigate through and operate.
10 January 2023
Scannned both of my vehicles and found no error codes or faults, which is comforting. Between the two vehicles, which I have owned for many years the Vident OBD11 will serve itself for a long time. There have been error codes previously and end up costly when taken to a mechanic. Although, this maybe the case sometimes, minor issues you can correct yourself. Five minutes in the workshop can be expensive. There are a lot of functions this scanner can perform which I'm about to discover in the future. I think this tool is a must in your arsenal.
27 December 2022
Disappointed item does not do as advertised
27 December 2022 Response
Sorry to hear that Doanld and sorry to see there is no inquiry from you trying to troubleshoot or to understand the scanner from your end as we would be happy to help. There is the Holden function list for this scanner under the 'Vehicle Coverage Options' on the i400AU so not sure if you checked that to understand the capability of the scanner going down to vehicle model/ year make. Anyhow feel free to contact us and if you ar not happy with the scanner to return the unit for refund as long as it is in the original conditions and within 30 days from the delivery date if needed.
Brilliant Scan tool, did the job I required
16 December 2022

I’m super happy with the scanner tool and a great tool and thank u
11 December 2022
Excellent scanner can do everything on VX commodore v6 auto. SRS code fix.
26 November 2022
Bloody ripper. Paid for itself first day I had it. I was only using a really cheap tool before, but this is great and easy to work out how to use. Should of had one ages ago.
8 November 2022
Love it best scan tool for tech tool II good features tuning it’s paid for it self in 1 week Great for its price
29 October 2022
Purchased this and after one attempted use I returned it due to almost unusable screen size. I did not get to use a great deal of the functions on offer so hard for me to comment on that but the ones I did use seem to work ok.
17 October 2022 Response
Sorry to hear that. This is a stanrd screen for many of the hand held scan tools. Normally the screen size is fine for the other customers but we take your feed back on board. We do have options with bigger screens as well as tablets but unfortunately not in the price range you were looking at.
fantastic very happy did the job for what was required thank you registration of tool is a bit complicated.
14 October 2022
Worked perfectly on my Vz Commodore. Needed to clear fault code for airbag and it did it no problem. It has great features for this model. Awesome diagnostic tool for the money, I can totally recommend this tool.
9 October 2022
Very happy with these guys. Product is great, works really well and the service was great.
8 September 2022
Excellent purchase absolutely love it
15 August 2022
A bit clunky and could not get the device to communicate with the bcm/airbag system
10 August 2022
Great value tool.
5 August 2022
Scans all codes and records for the price a bargain I have given it five stars
21 July 2022
This scan tool is user friendly & identified then on command cleared my airbag error code & airbag light. Turn ignition off for a few minutes or more after clearing code.Have saved already on one mobile mechanic fee. Will use this tool with confidence in the future. On initial purchase check whether software for your vehicle is already loaded to inserted "SIM like" card. Instructions advise you to acquire software over internet, this was not necessary fortunately as I had specified vehicle make & model on puchase
5 July 2022
Worked perfectly. Cleaned up SRS codes and waiting on new parts. Allowed me to find unknown problem of cam sensor and clear codes. Wish new cars didn't have as much electronics.
