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.
ECM Inputs
•Brake Switch Sensor
• A/C Pressure Switch
• Camshaft Position (CMP) Sensor
• Crankshaft Position (CKP) Sensor
• Engine Coolant Temperature (ECT) Sensor
• Intake Air Temperature (IAT) Sensor
• Air Flow Sensor
• Throttle Position Sensor (integral with Electronic Throttle Control Actuator)
• Power Steering Switch
• Accelerator Pedal Position (APP) Sensor
• Knock Sensor
• Oxygen Sensor (Upstream & Downstream)
• 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 heating coil (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.

The battery, starting and charging systems operate in conjunction with one another, and must be tested as a com-
plete system. For correct operation of starting/charging systems, all components used in these 3 systems must per-
form within specifications. When attempting to diagnose any of these systems, it is important that you keep their
interdependency in mind. These components form two separate circuits, a high amperage circuit that feeds the
starter motor up to 150 amps, and a control circuit that operates on less than 20 amps.

Starter Motor Bench Test
Starter motor operation can be confirmed by performing
the following free-running bench test. This test can only
be performed with the starter motor removed from the
vehicle.1. Remove the starter motor from the vehicle (See Starter Motor Removal & Installation in Section 05
Starting and Charging).
2. Mount the starter motor securely in a soft-jawed bench vise. The vise jaws should be clamped on
the mounting flange of the starter motor (never
clamp on the starter motor by the field frame).
3. Connect a suitable volt-ampere tester and a 12 V battery to the starter motor in series, and set the
ammeter to the 100 A scale.
4. Install a jumper wire from the solenoid terminal to the solenoid battery terminal. The starter motor should oper- ate. If the starter motor fails to operate, replace the faulty starter motor assembly.
5. Adjust the carbon pile load of the tester to obtain the free running test voltage.
6. Note the reading on the ammeter and compare this reading to the free-running test maximum amperage draw.
7. If the ammeter reading exceeds the maximum amperage draw specification, replace the faulty starter motor assembly.
Starter Solenoid Test
This test can only be performed with the starter motor removed from the vehicle.
1. Remove the starter motor from the vehicle (See Starter Motor Removal & Installation in Section 05
Starting and Charging).
2. Disconnect the wire from the solenoid field coil ter- minal.
3. Check the solenoid for continuity between the sole- noid terminal and the solenoid field coil terminal
with a continuity tester. There should be continuity.
If there is continuity, go to Step 4. If not, replace
the faulty starter motor assembly.
4. Using a continuity tester, check for continuity between the solenoid terminal and the solenoid
case. There should be continuity. If not, replace the
faulty starter motor assembly.
