What are the primary checks for the ignition coil/igniter units used on Lexus ES300?

Primary and secondary resistance checks for ignition coil/igniter units on some Toyota and Lexus models don't apply to newer ones. The only test is to substitute a known good unit, which isn't practical for home mechanics. If all other ignition malfunction causes are ruled out, a faulty ignition coil/igniter unit is likely. To check primary resistance on some models, disconnect the electrical harness connector(s) from each coil and use an ohmmeter across the coil primary terminals. For secondary resistance, detach and label the spark plug wires from each coil and use an ohmmeter across the two secondary terminals. If resistance readings are off, replace the coil. When replacing, disconnect the battery's negative cable and follow specific removal and installation procedures for four-cylinder or V6 models.

Lexus ES300 Ignition Coil

Lexus ES300 Ignition Coil provides the jolt that converts battery current into a fiery spark so that fuel immediately ignites for smooth acceleration. Wrapped around an iron core, its primary and secondary copper windings create a magnetic field at 12 volts then collapse to unleash between 15,000 and 40,000 volts, jumping the gap at each of the spark plugs. Early ES300 sedans applied a single Ignition Coil and distributor and applied a pattern of routing high tension energy by way of a cap, rotor and wires, which has been applied on other Lexus powertrains of the time. Mid-generation ES300 versions adopted waste-spark coil packs, with two cylinders per coil to fire one spark while the companion cylinder exhausts, improving parts and increasing Lexus reliability. Later ES300 years moved into coil-on-plug layout where there will also be one Ignition Coil directly on top of every plug, eliminating all long wires and helping to sharpen the spark timing. Each Ignition Coil is sealed in heat-resistant epoxy, resistant to vibration and moisture, and the failure of an Ignition Coil can cause rough idle while the rest of the system maintains overall Lexus drivability at a pretty good level.
