The need for advanced and reliable diagnostic tools in automotive repair is ever-increasing, especially when dealing with complex General Motors (GM) vehicles. For professionals and enthusiasts seeking in-depth access to their GM cars and trucks, the AutoEnginuity scan tool emerges as a powerful solution. This article explores the enhanced GM-family interface (EI02) for AutoEnginuity, designed to provide unparalleled diagnostic capabilities for GM vehicles from 1996 to 2025*.
AutoEnginuity Scan Tool Enhanced GM Interface in Action: Diagnosing a Buick Vehicle
Deep Dive into GM Systems with Enhanced Interface
The Enhanced Interface for GM-family vehicles from AutoEnginuity is engineered to go beyond basic OBD-II scanning. It grants users access to a staggering 8,400+ sensors across various critical systems, including engine, transmission, body, and chassis. This extensive sensor coverage is comparable to factory diagnostic tools, ensuring you capture a wealth of data for accurate and thorough vehicle analysis.
For automotive tuners, the enhanced GM interface offers specialized functions like the Crank Variation Learned test for a wide range of vehicles. This feature is invaluable for performance tuning and ensuring optimal engine operation after modifications.
Furthermore, AutoEnginuity expands its support to include Engine and Transmission diagnostics for Workhorse vehicles manufactured between 2004 and 2008 (P42 Series, W22 Series, W24 Series, W52 Series, LF72 Series, P32 Series, W18 Series, FE20 Series, W42 Series). This dedicated coverage for Workhorse chassis makes AutoEnginuity a versatile tool for diverse automotive applications.
With support for over 6,000 sensors across 100 systems, AutoEnginuity’s GM-family interface rivals factory tools in its diagnostic breadth. This extensive coverage empowers technicians and enthusiasts to delve deep into vehicle health and performance.
Bi-Directional Control: Take Command of Your GM Vehicle
AutoEnginuity truly sets itself apart with its robust bi-directional control capabilities, offering over 2,000 commands and key system-level tests. Unlike standard scan tools that merely observe vehicle operation, AutoEnginuity allows you to actively interact with your GM vehicle’s systems.
This bi-directional functionality unlocks a new dimension in diagnostics and repair. Instead of just reading data, you can send commands to the vehicle’s modules to perform tests, calibrations, and activations. This level of control is crucial for tasks such as:
- ABS Automated Bleed Routine: Effectively bleed the ABS system, ensuring optimal braking performance.
- Crank Variation Learn: Essential for engine tuning and component replacement, ensuring accurate crankshaft position sensing.
- Injector Flow Rate Programming (CAN-based Diesels): Precisely program injector flow rates for optimal diesel engine performance and emissions.
- Key Fob Programming: Program or reprogram key fobs, a necessary function for key replacement or adding new keys.
- SDM Setup and Part Number Programming: Configure and program the Sensing and Diagnostic Module (SDM) related to airbag systems.
- Idle Learn & TDC Learn: Perform idle and top dead center learning procedures, critical after certain repairs or adjustments.
- Tire Pressure Sensor ID Programming: Program tire pressure sensor IDs, necessary when replacing sensors or rotating tires.

Example Coverage: Cadillac Escalade ’02 & Chevrolet Pickup 1500 ’99
To illustrate the depth of coverage, consider the example of a 2002 Cadillac Escalade. AutoEnginuity provides extensive access to systems like the Body Control Module, Engine, Heating and Air Conditioning, Memory Mirror Module, OnStar, Steering Column Lock Module, Supplimental Inflatable Restraint, Transmission, Vehicle Immobilizer Module, and 4WAL. Within each system, you gain access to detailed sensor lists and actuation controls.
For instance, exploring the Cadillac Escalade ’02 coverage reveals capabilities such as viewing Body Control Module actuation lists and sensor data, accessing engine parameters, and interacting with the heating and air conditioning system.
Similarly, for a 1999 Chevrolet Pickup 1500, AutoEnginuity provides access to systems like Engine, EVO, Transmission, and 4WAL. You can delve into engine sensor lists, examine transmission parameters, and diagnose 4-Wheel Anti-Lock (4WAL) brake systems.
These examples are just a glimpse of the extensive vehicle coverage offered by the AutoEnginuity enhanced GM interface. From Cadillac to Chevrolet, GMC, Pontiac, and more, AutoEnginuity delivers comprehensive diagnostic capabilities across the GM family.
Please note: AutoEnginuity enhanced GM interface does not support ALDL systems (OBD-I controllers), typically found on pre-’96 MY vehicles for non-powertrain systems. It also does not support KWP2000 and ISO based modules found in certain models like SAAB, Opel, Vauxhall, Chevy Optra, Chevy Tracker, Chevy Prism, Chevy Aveo, Saturn VUE, Pontiac Vibe, Cadillac Catera, and KWP2000-based CTS vehicles (for these, the Enhanced Toyota interface is recommended). GEO vehicles are also not supported.
Conclusion: Empowering GM Diagnostics
The AutoEnginuity Enhanced GM-family interface is a powerful and versatile tool for anyone working with GM vehicles. Its extensive sensor coverage, bi-directional control features, and broad vehicle compatibility make it an invaluable asset for professional technicians, serious DIYers, and automotive enthusiasts. Unlock the full diagnostic potential of your GM vehicles with the AutoEnginuity scan tool and its enhanced GM interface.
