IAC Signal Tester
Diagnosing Idle Air Control problems on EFI engines can be a real challenge without the proper test equipment. This electronic diagnostic tester is used to check the condition of the ECM's Idle Air Control electronic driver circuit. The ECM's driver circuit controls the movement of the IAC motor's air bypass valve and thereby allows the ECM to regulate idle speed. This tester provides a visual display of the ECM's two IAC driver signals and indicates both the polarity and switching activity of the IAC signals. This is a real time saving device when troubleshooting IAC problems. Part number: 94016. $54

EFI Sensor Test Lead Kit


This complete kit of adapters is designed to make the job of testing EFI sensors a whole lot easier! Properly functioning sensors are absolutely essential on any EFI equipped engine. When your diagnostic tool indicates a sensor problem, your next task is to verify the sensor's operation with a digital voltmeter or sensor tester. Most voltmeters and sensors testers are supplied with insulation piercing test probes which punch a hole in the sensor wire's insulation providing a path for moisture and corrosion. These test adapters clip directly onto the sensor and provide easy access to the sensor's voltage supply and output terminals without piercing the wires! Save time and frustration. The kit includes adapters for MAP, IAC, CTS, MAT, TPS and Knock sensors. $120
Part Number 94025
CodeMate - EFI Code Reader
This pocket size tester serves as both an EFI Problem Indicator and a Spark Timing service tool. It is the perfect tool for low volume marine repair shops that troubleshoot a small number of EFI systems a year. This tool is the minimum required service tool needed to perform GM marine EFI diagnostic procedures. CodeMate allows fault codes to be read and allows base spark advance to be set when used with a timing light. Works with all Volvo Penta versions. Only works with Mercruiser engines prior to 2001. $120

TechMate Industrial
Hyster / Yale Scan Tool

This self-contained, hand-held diagnostic scan tool displays complete Hyster EFI system information to quickly perform component level diagnosis. TechMate displays live sensor readings, extracts ECM fault codes, and provides fault code explanations. Its built-in port fuel injector tester performs both single pulse and multi-pulse tests to locate multiport injector problems. TechMate also allows base spark advance to be set when used with a timing light. The tool is supplied with a deluxe padded storage case. $538

Hyster / Yale 3.0L Adapter
This adapter allow the TechMate scan tool to be connected to Hyster's new 3.0L EFI engine. Unlike the 2.2L and 4.3L EFI engines, the 3.0L is equipped with a new 10 pin diagnostic data connector. This new data connector eliminates the need for a separate 12 volt battery connection to power the TechMate scan tool. If you plan on servicing the 3.0L EFI engine, be sure to specify this optional adapter when ordering the TechMate tool. $66
