## Description

From the brand Topdon Your Ultimate Car Pal Provide Solution for Every Car Problems TOPDON Makes Car Repair Easier Jump Start Your Vehicle in Sec See More then The Human Eye One-Stop Battery Solution

Review: Great value. Lasts. Covers most important codes across manufacturers - Had it 2 years plus and used it for 6 different automatic cars (2 Honda CRVs, 2 Jaguar X types - petrol and diesel, and 2 LR Freelander 1's owned. It has worked very well and picked up problems more dedicated OBD readers did not. As for battery checker, great too. I cannot fault this device which I found easy to use and the value - £75 at the time - robustness and instructoons are all good. Recommend esp. If you have various models. It has saved me hundreds of pounds costing less than one garage checkup.
Review: Not for diagnosing. - Considering the price, a really good and fairly basic device. Bear in mind it is not strictly a diagnostic tool. It's a trouble code reader, eraser and "live" data viewer. Easy to update by visiting Topdon website and downloading the latest firmware April 2022 is the one that was available at the time of writing this. My Win 10 did disply a warning about downloading the update tool. Long, flexible cable and useful l.e.d. light incorporated into the plug. My car's OBD port is buried deep under the dash! No reference in the instructions about replacing the battery for the light. Probably a button cell and accessible by removing the small screws on the plug? Edited to add that there are two CR1220 cells in the plug. Without encouraging anyone to replace them, when necessary, they are easy to access with care. Doing so will probably invalidate any warranty though. Recommended for slightly more than very basic use.
