Autofix Explained

For a new generation of vehicles, welcome to an all-new repair guide. The Haynes Manual has inspired and helped DIY repairers for more than 60 years, but today’s modern vehicles come with new challenges that can only be tackled by a digital product.

When we first began selling manuals in the 1960s, vehicles were simple to maintain and there were relatively few models on sale. Today, electronics are a vital part of how your vehicle operates and there are more than 100,000 different variants of make/ model/ body type/ gearbox and engine.

So at Haynes, we knew that to continue offering a great product, we needed to take a brand-new approach - nothing less than a reinvention of the repair manual. With so many models on sale, it is impossible to strip down and rebuild enough cars to cover the market properly. Instead, Haynes AutoFix is based upon workshop data with added DIY tutorials full of general tips and techniques.

The instructions are no longer step-by-step and are best-suited to confident home mechanics or professionals.

But we’re adding something new, powerful and very important.

Modern cars are equipped with dozens of sensors and ECUs (control units). Today, the first step when servicing a car is to plug a diagnostic tool into the OBD (on-board diagnostics) system of the vehicle.

So, we’re putting an electronics diagnosis module in the hands of DIY repairers for the first time. Enter a fault code and follow the instructions to test components in order, and establish the likely cause of a problem. Our tool goes far beyond what commonly available fault code readers offer, and puts you, the car owner, back in control. Even if you choose not to complete the repair yourself, you will know exactly what the problem is when you hand it over to a workshop.

Haynes AutoFix is not a Haynes Manual. We want to be very clear about this, but we know that our new product will enable many thousands of you to continue maintaining your vehicle and troubleshooting problems in a DIY environment.

Note: Autofix is a worldwide product. You will sometimes see RHD (right hand drive) or LHD (left hand drive) mentioned. On location diagrams, we sometimes have LHD drawings only; but they do apply to RHD vehicles in a mirror image.
