Product Description
Autel CAT14 Adapter — 14-Pin Caterpillar Off-Highway Vehicle Adapter
\nThe Autel CAT14 adapter is a purpose-built 14-pin connector for diagnosing Caterpillar engines on construction and agriculture equipment operating off-road. If your shop or fleet services CAT-powered machinery — excavators, dozers, motor graders, agricultural tractors — this is the adapter that bridges your Autel diagnostic tablet to those machines.
\n\nWhat the CAT14 Does
\nCaterpillar off-highway vehicles use a proprietary 14-pin diagnostic port that differs from standard on-highway connectors. The CAT14 adapter plugs into that port and connects to the Autel MaxiSYS MS909CV tablet and its VCI, enabling full engine diagnostics on Caterpillar-powered off-road equipment. Without this adapter, the MS909CV cannot communicate with CAT-engine machines — it is the required physical link for that coverage.
\n\nCompatibility
\n- \n
- Required tablet: Autel MaxiSYS MS909CV with Bluetooth MFVCI/J2534/RP1210 device \n
- Vehicle type: Off-highway construction and agriculture machines powered by Caterpillar engines \n
- Connection type: 14-pin Caterpillar proprietary diagnostic port \n
- Software requirement: MS909CV tablet and VCI must have the latest software updates installed before use \n
Who Needs This Adapter
\nThis adapter is for shops and fleets already running the MS909CV commercial vehicle diagnostic platform. If you are servicing heavy construction or agriculture equipment with Caterpillar engines, the CAT14 extends your existing investment to cover that off-highway work. It is a targeted add-on, not a standalone tool.
\nConsider the companion CAT 9-Pin Adapter (SKU: CAT9, 0) if you also service Caterpillar on-highway trucks, which use the 9-pin Deutsch connector. Many shops running mixed fleets keep both adapters on hand.
