Review on 🚛 Heavy Duty Truck Scanner RD801: Universal 24V Diesel OBD2 Scan Tool for Scania, Man, Hino, Fuso, UD, DAF - Check Engine Truck Scanner Diagnostic Tool by Kristopher Rodriguez

more from this scanner. It looks like this device was originally made for the European/Asian truck market and the US market was delayed. The unit has an engine scan range reserved for only a select few European/Asian engine manufacturers, making this range virtually useless for the US market. This doesn't necessarily mean that the scanner won't scan the engine, it simply means that some part of the device should be ignored unless you're scanning one of those selected engines. The kit includes a scanner that includes an attached cable with a 16-pin connector, a 9-pin and a 6-pin adapter, a USB cable for connecting to a computer, instructions, and a carrying case. The scanner cable is almost 46 inches long. The tote bag is a nice addition and looks high quality. The supplied manual contains basic information on how to operate the device, but has not been updated for the US market. The info doesn't clearly say how to scan US HD trucks, nor does it say that the engine section is for select engines only, although it's obvious if you go into that section and don't see engines from Cummins, Caterpillar, etc . sees. In the list. The guide tells you how to perform a software update, which means you contact the manufacturer to get a file that will download to your computer and then start after connecting the scanner with the supplied USB cable have connected. Wanting to make sure my devices are up to date with the latest software, I contacted the manufacturer at the email address provided in the manual. Unfortunately, the email in the manual is not good. There was a different email address on the product packaging, which I used to successfully contact the manufacturer. I asked them about receiving the update file and also asked about the "Engine" section of the device and if the device would scan my Cummins engine. They replied that they followed the update instructions in the manual and advised that the "Engine Scan" section should scan my engine. I emailed back and said that the manual said to contact them about the file, which I did in my original email, and that my engine wasn't listed in the "Engine Scan" section. They replied that I have the latest version on my device and that my engine should be scanned via the main scan section. Your customer service representatives should better understand their products. I used the scanner to scan the systems on my diesel motorhome. While not technically a heavy-duty truck, it is built on a Freightliner chassis and features a Cummins diesel engine and Allison transmission. There are two DTC/OBD sockets, one in the cab and one at the rear next to the engine. Both connectors are 9-pin. The scanner is well connected and powered on and appears to be accessing information, but I'm not sure if it's actually receiving data. All systems showed "No DTC information". While it is possible that no codes were present and this message is being received, I found it odd that the codes were not found on any system and the codes were not found in history. When trying to read live data, the scanner counts what I believe to be subsystems, but once the count is complete the scanner says "No Supported Stream". It looks like this scanner will not work for my purpose. All in all, I'm disappointed with these results.
