Connecting to OBD-I vehicles.

Some OBD-I vehicle communication adapters require 12 volts or ground be provided from the vehicle in order to establish proper communication between the vehicle and the scan tool. This is achieved by plugging the Lighter Power Cable and/or the Battery Power Cable into the silver power port on the side of the OBD-I adapter

No Communication Message.

“No Communication” may be the result of using an incorrect or failed Personality Key. If the correct Personality Key is being used and the issue persists, attempt communication using a new Personality Key appropriate for use with the make of the vehicle. For example, on Ford use the K17 key in place of the K20. If communication can be established with the new key the original key has most likely failed and should be replaced.

Please contact your local Snap-on Franchisee or visit to order a replacement key.

Damaged data cables or OBD-II adapters can also cause "No Communication" messages.

Where are the OBD-I adapters? Part numbers?

The majority of Snap-on’s new platform customers are working exclusively on 1996 and newer vehicles. To avoid having new platform customers purchase hardware they do not need, all new platforms include only the adapters needed for OBD-II vehicles. OBD-I adapters are offered as an optional accessory. The VERUS, MODIS, and SOLUS PRO are configured this way.

The VERUS compatible OBD-I adapters can be purchased as a set or individually from your local Snap-on Franchisee or online at
