Description
The Engine Control Module (ECM) consists of a microcomputer and electrical connectors containing circuits for signal
input, output, power supply and ground. The ECM controls the engine functions.
The following are the input and output components monitored by the ECM. The monitored functions include compo-
nents from the engine, ignition, transaxle, air conditioning, or any other ECM supported subsystem.
ECM Inputs
•Brake Switch Sensor
• Refrigerant Pressure Sensor
• Camshaft Position (CMP) Sensor
• Crankshaft Position (CKP) Sensor
• Engine Coolant Temperature (ECT) Sensor
• Manifold Absolute Pressure (MAP) Sensor (1.6L)
• Air Flow Sensor (1.8L)
• Throttle Position Sensor (Integral with Electronic Throttle Control Actuator)
• Power Steering Switch
• Accelerator Pedal Position (APP) Sensor
• Knock Sensor
• Oxygen Sensor (Upstream & Downstream)
• Vehicle Speed Sensor
• Clutch Pedal Switch (Manual transaxle only)
ECM Outputs
• Canister Control Valve
• Fuel Injectors
• Fuel Pump Relay
• Electronic Throttle Control Actuator
• Ignition Coil
• A/C Compressor
• Cooling Fan
• Oxygen Sensor Heater (Upstream & Downstream)
Operation
The ECM monitors components and circuits, and tests them in various ways depending on the hardware, function,
and type of signal. For example, analog inputs, such as throttle position or engine coolant temperature are typically
checked for opens, shorts and out-of-range values. This type of monitoring is carried out continuously. Some digital
inputs like vehicle speed or crankshaft position rely on rationality checks - checking to see if the input value makes
sense at the current engine operating conditions. These types of tests may require monitoring several components
and can only be carried out under appropriate test conditions.
The ECM is a pre-programmed, microprocessor-based digital computer. It regulates ignition timing, air-fuel ratio,
emission control devices, charging system, certain transmission features, speed control, air conditioning compressor
clutch engagement and idle speed. The ECM can adapt its programming to meet changing operating conditions.

Description
The Engine Control Module (ECM) utilizes integrated circuitry and information carried on the Controller Area Network
(CAN) data bus along with many hard wired inputs to monitor many sensors and switches inputs throughout the
vehicle. In response to those inputs, the internal circuitry and programming of the ECM allow it to control and inte-
grate many electronic functions and features of the vehicle through both hard wired outputs and the transmission of
electronic message outputs to other electronic modules in the vehicle over the CAN data bus.
The following are the input and output components monitored by the ECM. The monitored functions include compo-
nents from the engine, ignition, transaxle, air conditioning, or any other ECM supported subsystem.

Description
The fuel system consists of a fuel tank with a reservoir, fuel pump, fuel filter, fuel delivery line, fuel rail, fuel rail pulse
damper and fuel injectors. The Engine Control Module (ECM) controls the fuel system based on signal inputs. The
immobilizer module signals the ECM to activate the fuel system. If the ECM does not receive the proper signal from
the immobilizer module, the ECM will not allow the fuel system to operate.
•The ACTECO engine utilizes a returnless fuel delivery system.
• The MITSUBISHI engine utilizes a fuel return fuel delivery system.
WARNING!
Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related
component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instruc-
tions may result in serious personal injury.

Description
Vehicle wheel alignment is the positioning of all interrelated front and rear suspension angles. These angles affect the
handling and steering of the vehicle when it is in motion. Proper wheel alignment is essential for efficient steering,
good directional stability, and proper tire wear.
The method of checking a vehicle’s front and rear wheel alignment varies depending on the manufacturer and type
of equipment used. The manufacturer’s instructions should always be followed to ensure accuracy of the alignment.
On this vehicle, the suspension angles that can be adjusted are as follows:
Front Axle
•Camber
• Caster
• Toe-in
Rear Axle
• Camber
• Toe-in
Check the wheel alignment and make all wheel alignment adjustments with the vehicle standing at its proper curb
height specification. Curb height is the normal riding height of the vehicle. It is measured from a certain point on the
vehicle to the ground or a designated area while the vehicle is sitting on a flat, level surface.
Operation
Curb Height Measurement
The wheel alignment is to be checked and all alignment adjustments made with the vehicle at its required curb height
specification.
• Vehicle height is to be checked with the vehicle on a flat, level surface, preferably a vehicle alignment rack.
• The tires are to be inflated to the recommended pressure.
• All tires are to be the same size as standard equipment.
• Vehicle height is checked with the fuel tank full of fuel, and no passenger or luggage compartment load.
• Vehicle height is not adjustable.
• If the measurement is not within specifications, inspect the vehicle for bent or weak suspension components.
• Compare the parts tag on the suspect coil spring(s) to the parts book and the vehicle sales code, checking for
a match.
• Once removed from the vehicle, compare the coil spring height to a new or known good coil spring. The
heights should vary if the suspect spring is weak.
NOTE :
Prior to reading the curb height measurement, the front and rear of the vehicle must be jounced to settle the sus-
pension. Induce jounce by pushing down on the center of the bumper (fascia), using care not to damage the vehicle,
moving the vehicle up and down, gradually increasing the suspension travel with each stroke. Release the bumper at
the bottom of each stroke, repeating this action several times. Perform this to both front and rear suspensions an
equal number of times.
Pre-Wheel Alignment Inspection
Before any attempt is made to change or correct the wheel alignment, the following inspection and necessary cor-
rections must be made to the vehicle to ensure proper alignment. 1. Verify the fuel tank is full of fuel. If the fuel tank is not full, the reduction in weight will affect the curb height of the vehicle and the alignment specifications.
2. The passenger and luggage compartments of the vehicle should be free of any load that is not factory equip- ment.
