Pathfinder LE 2WD V6-3.5L (VQ35) (2001)
Ignition Control Module: Description and Operation
IGNITION COIL & POWER TRANSISTOR
The ignition signal from the ECM is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary circuit.
This on-off operation induces the proper high voltage in the coil secondary circuit.
