Thinkcar THINKTOOL Expert 191 Diagnostic Tool

Thinkcar THINKTOOL Expert 191 Diagnostic Tool

THINKTOOL Expert 191 is the entry model of Thinkcar's professional diagnostic range — and "entry" does not mean limited here. It performs full-system diagnostics, bi-directional actuation tests and ECU coding: not a code reader, but a workshop-grade diagnostic tablet. It supports CAN FD and DoIP, the protocols newer vehicles require.

What the Expert 191 Does

Three things decide a diagnostic tool's class: how many systems it reaches, whether it only reads or can also command, and whether it can write to a unit. The Expert 191 is at workshop level on all three.

Why CAN FD and DoIP Matter

CAN FD (Flexible Data-Rate) is the faster successor to classic CAN, adopted across many manufacturers. A tool without CAN FD cannot connect to those vehicles at all — not even to read a fault code.

DoIP (Diagnostics over Internet Protocol) carries diagnostic traffic over Ethernet and is common on current Jaguar Land Rover, VW group and BMW models, particularly for software update and coding work.

Expert 191 or Expert 391?

If your workshop regularly needs programming after a unit replacement, the 391 is the right tier; if diagnostics, service resets and coding are enough, the 191 is.

What the Expert 191 Does Not Do

Saying what a tool cannot do matters as much as saying what it can. From the manufacturer's chart, the Expert 191 does not have:

• Online ECU programming — no software flashing after a unit replacement. If you need that, the tier to move to is the Expert 391.
• ADAS calibration — lane-keep and adaptive-cruise camera calibration are not supported.
• Topology map — the module network diagram is not drawn; diagnosis runs through the system list.
• Remote video support and dual-vehicle diagnostics.
• No camera — VIN is entered manually or read through the automatic VIN query.
• PROG module is not supported.
• Electric vehicle (EV) and heavy-duty (HD) software packages are not offered for this model.

Expansion Modules

• Video scope (USB)
• THINKEASY battery test clip
• Scope Box (USB oscilloscope)
• USB printer
• TPMS module

Each module is bought separately, so a tyre shop can start with the TPMS module and an electrical diagnostician with the Scope Box.

Who It Is For

• Independent multi-brand workshops
• Service shops with heavy diagnostic and service-reset workloads
• Workshops whose older tool cannot reach newer vehicles for lack of CAN FD and DoIP
• Technicians who want to diagnose without removing parts, using bi-directional tests
• Single-discipline businesses (tyres, exhaust, brakes) that need service functions
