Frequently Asked Questions

Why are truck diagnostics essential?

There are multiple sensors and processors in a truck, from transmissions and fuel injectors, to exhaust systems and ignitions. Diagnostic equipment can identify any issues in the truck, helping to mitigate the risk of breakdown, and the cost of expensive repairs or replacements.

Can an automotive multimeter locate electrical faults?

An automotive multimeter can perform simple voltage tests to determine the health of your battery and alternator. A reading below 12.6V on a resting battery indicates a problem, and a reading outside 13.8V-14.4V with the engine running can point to a faulty alternator. This helps you diagnose the problem before it leaves you stranded.

How can I tell if the diagnostic tool will work with my truck?

Simple. If you add the item to your cart, and let us know your vehicle registration using the option on the cart page, we'll check the part fits before we process your order. If it doesn't match the vehicle, we'll get in touch to discuss your options.

When will I receive my diagnostic tool?

At Truckstop, we offer several tailored delivery solutions. We offer same-day delivery on all parts in stock placed before 11am to Worcestershire, Warwickshire, Herefordshire & Gloucestershire. For orders to the UK mainland, we offer next-day delivery by courier. You can learn more about our delivery solutions here.
