🔌 Function

The CDM combines ignition coil and capacitor discharge module functions, using trigger and stator inputs to fire the spark plug.

Common signs of failure:

• No spark on one cylinder

• Weak or intermittent spark

• Hard starting

• Misfire under load

• Spark loss when engine warms up

• Cylinder fault moves with the CDM when swapped

• Cracked case or damaged plug lead

• Corroded or loose CDM connector pins

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
