ICM:

Ignition Control Module.

IMRC:

Intake Manifold Runner Control

IPC:

Instrument Panel Cluster

ISC:

Idle Speed Control. A small electric motor mounted on the throttle body and controlled by the PCM. The PCM can control idle speed by commanding the ISC to adjust its position.

ISO:

International Organization of Standardization also know as International Standards Organization.

ISO 9141:

International Standards Organization OBDII communication mode, used by Chrysler and most foreign cars. One of three hardware layers defined by OBD II

J1850PWM:

established standard for OBD II scan tools

J1979 – SAE:

established standard for diagnostic test modes

J2012 – SAE:

KAM:

Keep Alive Memory

Knock Sensor (KS):

Used to detect engine detonation or knock. The sensor contains a piezoelectric element and is threaded into the engine block. Special construction makes the element sensitive only to engine vibrations associated with detonation.

Knock:

Uncontrolled ignition of the air/fuel mixture in the cylinder. Also referred to as detonation or ping. Knock indicates extreme cylinder pressures or “hotspots” which are causing the air/fuel mixture to detonate prematurely.

KOEO:

Key On Engine Off. Turn the ignition key to on, but don’t start engine.

KOER:

Key On Engine Running. Start the vehicle.

LCD:

Liquid Crystal Display

LTFT:

Long Term Fuel Trim
