About this deal

CAN employ a twisted pair of wires (one wire CAN high typically 3.5-2.5 volts oscillating and the other CAN low typically 2.5 – 1.5 volts oscillating) that loop the vehicle, connecting all the modules on the network. Scan tool plug connector fault – I’ve worn out a few of these guys; they work hard and wear out. The tool’s plug spades can become bent or worn, which causes a poor connection or no connection. Wiggling the plug in the OBD port usually lets you know it’s time to change the cable.

OBD scanners have become an essential part of the home mechanic’s toolkit, with the ability to read engine fault codes crucial to diagnosing and repairing modern cars and vans. Draper has a good reputation for making products that stand the test of time, and we have no reason to doubt this code reader's staying power; at the time of testing it was one of the pricier offerings here, but deserves its Haynes Recommended award. It also has permanent code retrieval, on-board monitor test (Mode 6, for additional component/system monitoring), reads fault code pending data, DTC code lookup function and lets you reset the oil change indicator.Scan tool faults aren’t that common, I’ve never broken a tool yet, but I have worn out a few cable connectors. Here’s a list of scan tool problems and what you can do to fix them:

Made for all kinds of users, from professionals to home mechanics, this industry standard OBD II reader pinpoints why the vehicle’s engine light is showing. Experience has shown me it’s best to look for clues and ask some questions if needed before testing components. I’ll look for signs of recent accident damage, water leaks, heavy corrosion, or recent works carried out on the vehicle. The product is supplied with an in-depth user manual which explains generic diagnostic codes and operation instructions. Hard codes, on the other hand, are current static faults that are affecting vehicle system performance. These types of codes need to be repaired before they can be cleared from the computer module.Your vehicle is stuffed with modules, each one tasked with a particular system to manage. Your ECU (Engine Control Unit) takes care of the engine, your TCM (Transmission Control Module) takes care of the tranny, and your BCM (Body Control Module) takes care of the vehicle accessories. You get the idea. This reader’s large colour display looks like it should be a touchscreen, but it’s not. However, the physical buttons make navigation a cinch.
