Coil On Plug (COP) and Signal Probe — Non-Intrusive Testing

The coil–on–plug and signal probe works with most COP systems; it requires no special adaptors, no foil strips, and no batteries. The Pico coil-on-plug and signal probe eliminates the need for back-probing: to use the probe simply press the probe against the coil.

Along with testing COP systems, the coil-on-plug and signal probe can also be used to obtain many other signals, including a secondary ignition waveform on conventional ignition systems.

Designed to save you time, effort and money, the coil-on-plug and signal probe is the fastest way to test both conventional coil-on-plug secondary ignition systems.

Non-intrusive diagnosis is essential during the initial inspection of a vehicle and the flexible COP/ Signal Probe becomes invaluable in these scenarios. Misfires are a typical example of where the COP probe excels especially with modern multi cylinder engines and restricted access to coil units. The shaft of the signal probe can be formed into any shape in order to access coil units that may be buried under intake ducting or manifold assemblies. Once an offending cylinder has been identified, authorisation can be requested before commencing with a time consuming repair whilst safe in the knowledge the misfire has been delivered before disassembly. The COP/Signal Probe is not only confined to misfire detection:

• COP units (including restricted access units) HT functionally check
• HT Leads and coil towers for HT functionality
• Injectors (Petrol/Diesel) solenoid type for an indication of operation
• Solenoids for operation check
• Oil control valves for operation check
• Throttle motors for activity check
