GENERAL INFORMATION

The Powertrain Control Module (PCM) is given responsibility for the operation of the emission control devices, cooling fans, ignition and advance and in some cases, automatic transaxle functions. Because the PCM oversees both the ignition timing and the fuel injection operation, a precise air/fuel ratio will be maintained under all operating conditions. The PCM is a microprocessor, or small computer. Which receives electrical inputs from several sensors, switches and relays on and around the engine.
Based on combinations of these inputs. The PCM controls outputs to various devices concerned with engine operation and emissions. The control module relies on the signals to form a correct picture of current vehicle operation. If any of the input signals is incorrect. The PCM reacts to whatever picture is painted for it. For example, if the coolant temperature sensor is inaccurate and reads too low, the PCM may see a picture of the engine never warming up. Conse-Quenlly, the engine settings will be maintained as if the engine were cold. Because so many inputs can affect one output, correct diagnostic procedures are essential on these systems.

One part of the PCM is devoted to monitoring both input and output functions within the system. This ability forms the core of the self-diagnostic system. lf a problem is detected within a circuit, the control module will recognize the fault. Assign it a Diagnostic Trouble Code (DTC), and store the code in memory. The stored code(s) may be retrieved during diagnosis.

While the OBD-II system is capable of recognizing many internal faults, certain faults will not be recognized. Because the control module sees only electrical signals, it cannot sense or react to mechanical or vacuum faults affecting engine operation. Some of these faults may affect another component which will set a code. For example, the PCM monitors the output signal to the fuel injectors, but cannot detect a partially clogged injector. As long as the output driver responds correctly, the computer will read the system as functioning correctly. However, the improper flow of fuel may result in a lean mixture. This would, in turn, be detected by the oxygen sensor and noticed as a constantly lean signal by the PCM. Once the signal falls outside the pre-programmed limits, the control module would notice the fault and set a trouble code.
Additionally, the OBD-II system employs adaptive fuel logic. This process is used to compensate for normal wear and variability within the fuel system. Once the engine enters steady-state operation, the control module watches the oxygen sensor signal for a bias or tendency to run slightly rich or lean. II such a bias is detected, the adaptive logic corrects the fuel delivery to bring the air/fuel mixture towards a centered or 14.7:1 ratio. This compensating shift is stored in a non-volatile memory which is retained by battery Power even with the ignition switched OFF. The correction factor is then available the next time the vehicle is operated.


READING CODES

WITH A SCAN TOOL

The Diagnostic Link Connector (DLC), under the left-hand side of the instrument panel, must be located to retrieve any DTC's. Reading the control module memory is on of the first steps in OBD II system diagnostics. This step should be initially performed to determine the general nature of the fault. Subsequent readings will determine if the fault has been cleared. Reading codes can be performed by any of the methods below:
- Read the control module memory with the Generic Scan T 001 (GST)
- Read the control module memory with the vehicle manufacturer's specific tester
To read the fault codes, connect the scan tool or tester according to the manufacturer's instructions. Follow the manufacturer's specified procedure for reading the codes.

WITHOUT A SCAN TOOL

The Diagnostic Link Connector (DLC), under the lell-hand side of the instrument panel, must be located to retrieve any DTC's.
In 1996, all Mitsubishi switched from an arbitrary code listing and format, to the federally regulated On Board Diagnostics 2nd Generation (OBD II) code system. Normally, OBD II equipped vehicles do not have the option of allowing the person servicing the vehicle to flash the codes out with a voltmeter, usually a scan tool is necessary to retrieve OBD II codes. Mitsubishi, however, does provide this option.

The Federal government decided that it was time to create a standard for vehicle diagnostic systems codes for ease of servicing and to insure that certain of the vehicle's systems were being monitored for emissions purposes. Since OBD II codes are standardized (they all contain one letter and four numbers), they are easy to decipher.
The OBD II system in the Mitsubishi models is designed so that it will flash the DTC's out on a voltmeter (even though a scan tool is better). However, the first two characters of the code are not used. This is because the transaxle is a part of the Powertrain, so all transaxle related codes will begin with a P. Also, since there are no overlapping numbers between SAE and Mitsubishi codes, the second digit is also not necessary.
The system flashes the codes out in a series of flashes in three groups, each group corresponding to one of the three last digits of the OBD II code. Therefore, Code P0753 would be flashed out in seven flashes, followed by five flashes, then by three flashes. Each group of flashes is separated by a brief pause. All of the flashes are of the same duration, with the only exception being zero. Zero is represented by a long flash. Therefore, seven flashes, one long flash, two flashes would indicate a P0702 code (shorted TP sensor circuit).
To retrieve the codes, perform the following:
1. Perform the preliminary inspection, located earlier in this section. This is very important, since a loose or disconnected wire, or corroded connector terminals can cause a whole slew of unrelated DTC's to be stored by the computer, you will waste a lot of time performing a diagnostic "goose chase."
2. Grab some paper and a pencil or pen to write down the DTC's when they are flashed out
3. Locate the Diagnostic Link Connector (DLC), which is usually under the lelt-hand side of the instrument panel.
4. Start the engine and drive the vehicle until the transaxle goes into the failsafe mode.
5. Park the vehicle, but do not turn the ignition OFF. Allow it to idle.
6. Attach a voltmeter (analog or digital) to the test terminals on the Diagnostic Link Connector (DLC). The negative lead should be attached to terminal 4 and the positive lead to terminal 1.
7. Observe the voltmeter and count the flashes (or arm sweeps if using an analog voltmeter); note the applicable codes.
8. Alter all of the DTC(s) have been retrieved, fix the applicable problems, clear the codes, drive the vehicle, and perform the retrieval procedure again to ensure that all of the codes are gone.



CLEARNING CODES

WITH A SCAN TOOL

Control module reset procedures are a very important part of OBD II System diagnostics, This step should be done at the end of any fault code repair and at the end of any driveability repair. Clearing codes can 00 performed by any of the methods below'
- Clear the control module memory with the Generic Scan Tool (GST)
- Clear the control module memory with the vehicle manufacturer's specific tester
The MIL will may also be deactivated for some codes if the vehicle completes three consecutive trips without a fault detected with vehicle conditions similar to those present during the fault.

WITHOUT A SCAN TOOL

If there are still codes present, either the codes were not properly cleared (Are the codes identical to those flashed out previously?), or the underlying problem is still there (Are only some of the codes the same as previously?).
