Description
Ignition timing is controlled by the electronic control ignition timing system.
The standard reference ignition timing data for the engine
operating conditions are pre-programmed in the memory of the ECM (Engine
Control Module).
Description
An ignition coil is an induction coil in an engine's ignition
system which transforms the battery's low voltage to the high voltage
needed to create an electric spark in the spark plugs to ignite the
fuel.
Inspection

Turn the ignition switch OFF.
2.
Disconnect the temperature control actuator connector.
3.
Verify that the temperature control actuator operates to the
warm (Driver's side) or cool (Passenger's side) position when connecting
12V to terminal 3 and grounding terminal 4.
