The Actron Elite Autoscanner CP9185 is marketed as a versatile scan tool capable of handling both OBD1 and OBD2 vehicles. This review delves into its features, performance, and overall value based on hands-on testing.

Actron CP9185: Initial Impressions and Packaging
The Actron CP9185 arrived in a soft case containing the scanner, a main cable, a USB cable, a short OBD2 (16-pin) adapter, and an instruction booklet. Notably, the advertised CD containing the full user manual and PC software was missing. The scanner itself was in perfect condition. Purchased from Amazon for $175 (including shipping), this price proved to be a significant outlier, with subsequent listings and Actron’s direct price considerably higher.

The CP9185 features a power button but requires an external 12V power source (either from the vehicle’s DLC or a DC adapter) to illuminate the backlight. This is important for OBD1 vehicles, which typically lack power at the DLC. OBD2 vehicles provide power through the DLC.
OBD1 Performance: A Strong Showing
For OBD1 functionality, the optional CP9127 adapter cable (approximately $35) is required. This includes a 12-pin short adapter and a cigar-lighter power adapter for the scanner. Testing on various F-body vehicles (94/95 LT1, 94/95 L34, and 86 5.0L/carb) revealed impressive data retrieval. Live data streams, current and historical DTCs, and a functional field service mode (grounding the field service pin on the DLC) were consistently available. However, using the OBD2 cable on 95 models for field service mode requires manually connecting pin 6 to pin 12 due to signal relocation in later models to avoid CAN signal conflicts.

OBD2 Performance: A Disappointment
The Actron Elite Autoscanner’s OBD2 performance was underwhelming. Functionality was comparable to significantly cheaper OBD2 code readers, such as the Autel Maxiscan MS310, lacking advanced features found in other scan tools. Even the OBDWiz software bundled with the budget-friendly ELMScan-5 Compact adapter offers a more comprehensive OBD2 experience.
Additional Features and Limitations of the CP9185
The CP9185 lacks support for ABS or SRS modules and actuator tests. Graphing functionality is limited to some OBD2 parameters, with low resolution and no pausing capability for detailed analysis. Data logging is available for both OBD1 and OBD2, but recording times are short (often under 20 seconds) and update rates are slow. PC interface is restricted to transferring logged data in text format only. Several screenshots below showcase the data displayed for a 1994 LT1 engine.

Actron CP9185: Final Verdict and Recommendation
The Actron Elite Autoscanner CP9185 excels in its OBD1 capabilities, providing comprehensive data and functionality for older vehicles. However, its subpar OBD2 performance and limited extra features make it a poor value proposition compared to other scan tools on the market. Recommendation: Consider the CP9185 only if your primary need is scanning OBD1 vehicles. For OBD2 diagnostics, more affordable and feature-rich options are available.
