Magnetic Clutch Relay: Description and Operation

Air Conditioning Switch And Relay Circuit

LOCATION

The A/C relay is located on the left fender apron.

OPERATION

When the driver turns on the A/C system, and the engine temperature is below 238 F, a positive voltage signal is supplied to the ECM (as anindication that the A/C system is needed) and to one side of the A/C relay coil. The ECM determines if engine conditions are suitable for A/Coperation (idle speed, ignition timing and air/fuel mixture). If conditions are suitable for A/C operation, the ECM supplies the ground circuit forthe A/C relay coil, energizing it. This allows the relay to supply voltage to the compressor clutch.

Engine Controls - PCM Reprogramming Procedure

No: TSB-03-00-015 DATE: September, 2003MODEL: All models

SUBJECT:REPROGRAMMING WITH THE MUT-III
PURPOSE

This bulletin contains general instructions for reprogramming a vehicle PCM using the MUT-Ill vehicle communication interface (VCI) unit. Beforebeginning reprogramming, you must first transfer the reprogramming data to a PC memory card adapter equipped with a compact flash memory chip.New data is transferred from a DVD to the PC hard drive, then to the PC memory card. After data is in the memory card, it can be downloaded to theVCI, then to the vehicle's PCM (ECU).

The MUT-III is capable of both automatic reprogramming (it automatically selects the appropriate database) and manual reprogramming (you select thedatabase). Automatic reprogramming is recommended for most typical reprogramming situations. If automatic reprogramming is not successful, trymanual reprogramming.

Refer to the flow chart and the following steps to determine if the vehicle requires replacement of the ECM.

1.
Make sure the ignition is in the OFF position, then connect the MUT-II scan tool to the data link connector. Turn the ignition switch ON. Confirmthe MUT-II scan tool communicates properly. Turn the ignition switch OFF for 12 seconds, then proceed with Step 2.

2.
Check the MIL ("Check Engine" light) with IGN ON and engine OFF. Does the MIL illuminate momentarily? If YES, proceed to Step 3. If NO,repair the condition. Check the MIL again and then continue.

3.
Start engine. If the MIL illuminates with the engine running, refer to service manual section 13 to correct any existing DTC(s), then continue. Ifthe MIL does not illuminate, go to Step 4.

4.
With the MUT-II scan tool, check for MIL status ON (see note below). If MIL status is ON, and the "Check Engine" light is not illuminated, go toStep 5 (replace the ECM). If MIL status is OFF, the vehicle has the correct ECM and no further action is needed.

:NOTE

Location of MIL status using MUT-II:
a. Select MFI
b. Select DTC, and read MIL status.

5. Refer to the chart in the PARTS INFORMATION section of this bulletin and choose the correct ECM for the vehicle you are repairing.

Recall - ECM Replacement

No.: EMR-02-001DATE: December, 2002MODEL: See Below

SUBJECT:1996 MODELS; MIL COMMAND "ON" WITH NO MILILLUMINATION - EMISSIONS RECALL
PURPOSE

Mitsubishi Motor Sales of America, Inc. (MMSA) is recalling certain 1996 model year vehicles for an OBD-III emissions related condition. TheEnvironmental Protection Agency (EPA) and the California Air Resources Board (CARB) have been notified about this recall.
BACKGROUND INFORMATION

Symptom/Condition

During a State Inspection and Maintenance (I/M) program that uses the OBD II system for pass/fail determination, some early production 1996 modelyear vehicles may fail. The failure occurs when the MIL status is ON (MIL Commanded On), but the MIL ("Check Engine" light) is not illuminated.
Remedy

Using the MUT-II scan tool, check the OBD II system for a MIL status ON condition on the affected vehicle. If the MIL status ON condition is presentand the MIL is not illuminated, replace the ECM with the new updated part.

:NOTE

Not all vehicles will require ECM replacement. Be sure to follow the test instructions closely to determine if a particular vehicle does indeed need anew ECM.

Refer to the flow chart and the following steps to determine if the vehicle requires replacement of the ECM.

1.
Make sure the ignition is in the OFF position, then connect the MUT-II scan tool to the data link connector. Turn the ignition switch ON. Confirmthe MUT-II scan tool communicates properly. Turn the ignition switch OFF for 12 seconds, then proceed with Step 2.

2.
Check the MIL ("Check Engine" light) with IGN ON and engine OFF. Does the MIL illuminate momentarily? If YES, proceed to Step 3. If NO,repair the condition. Check the MIL again and then continue.

3.
Start engine. If the MIL illuminates with the engine running, refer to service manual section 13 to correct any existing DTC(s), then continue. Ifthe MIL does not illuminate, go to Step 4.

4.
With the MUT-II scan tool, check for MIL status ON (see note below). If MIL status is ON, and the "Check Engine" light is not illuminated, go toStep 5 (replace the ECM). If MIL status is OFF, the vehicle has the correct ECM and no further action is needed.

:NOTE

Location of MIL status using MUT-II:
a. Select MFI
b. Select DTC, and read MIL status.

5. Refer to the chart in the PARTS INFORMATION section of this bulletin and choose the correct ECM for the vehicle you are repairing.

THE FOLLOWING THREE STEPS ARE REQUIRED BY LAW.

6.
Using a ball-point pen, enter the appropriate ECM part number, this Emissions Recall Bulletin number (EMR-02-OO1), your dealer code, and thecurrent date on the "Control Module" Label (part no. MSSF-024G-00).

7. Place the "Control Module" label on the new ECM.

8.
FOR VEHICLES REGISTERED IN CALIFORNIA ONLY - Complete and provide to the vehicle owner a VEHICLE EMISSION RECALL -PROOF OF CORRECTIONS FORM.

9. Refer to section 13 of the service manual for ECM location and procedures. Replace the ECM with the new, updated ECM.

10.
After ECM replacement, engine idle may be unstable. To stabilize engine idle and ECM control conditions, start the engine and let it idle for 10minutes under the conditions shown below:

^ Engine Coolant temperature: 85 - 95C (185 - 203F)
^ Lights and all accessories: OFF
^ Transmission/Transaxle: "N" or "P" position
^ Steering wheel: straight-forward position.

:NOTE

After ECM replacement, readiness codes must be re-established by completing the recommended OBD-II Drive Cycle TSB-00-13-005) beforereturning to the I/M station for testing.
