Scanner accessory FAQs

Common questions on accessories.

Are accessories brand-specific?

Yes. Most scanner accessories are brand and model-specific. Check compatibility before ordering.

OBD-I vs. OBD-II?

OBD-I: older pre-1996 diagnostic protocols. OBD-II: standardized 1996+ diagnostic protocol. OBD-II is the modern standard; OBD-I requires specialty cables for older vehicles.

Can I extend my base scanner?

Depends on scanner. Some scanners support add-on cables and adapters; others are limited to built-in coverage. Check spec sheet.

Delivery?

Ships UPS/FedEx ground. Free U.S. shipping.

Warranty?

Standard manufacturer warranty, typically 1-year on cables and adapters.

Best value add-on?

Depends on vehicle mix. Call (470) 208-2754 with your vehicle list for personalized recommendation.

Can accessories break my scanner?

No. Proper accessories are designed for safe use with compatible scanners.

Return policy?

Standard Pitstop Pro return policy. Contact support if accessory doesn't work with your specific scanner.
