TR-TS,KR-KS SERVICE ADJUSTMENTS

NOTE: Prior to and after completion of service adjustments, it is advisable to carry out a system self diagnosis check to ensure of optimum performance.


Ignition Timing

(1) Connect an engine tachometer and start the engine.

(2) Run the engine until normal operating tempera ture is reached.

(3) Ensure that all lights and accessories are switched off.

(4) Check that idle speed is as specified with the cooling fan OFF. If necessary, adjust using procedure detailed later in this section.

(5) Switch engine OFF and connect the spark advance cut terminal to earth with a suitable jumper lead, refer Fig. 46.

(6) Connect a suitable timing light to No. 1 cylinder and start the engine.

NOTE:
(i) Do not disconnect high tension leads with the engine running as damage to the ignition control unit can occur.
(ii) Do not puncture cables, boots or nipples with test probes. Always use proper adaptors. Puncturing the spark plug cables with a probe will damage the cables. The probe can separate the conductor and cause high resistance. In addition, breaking the rubber insulation may permit secondary current to arc to ground.
(iii) Do not connect timing light primary lead to the alternator output terminal as alternator damage will occur.

(7) Aim the timing light at the timing plate and check that ignition timing is to specifications. If necessary, adjust to specification by loosening the distributor clamp bolt and rotating the distributor.

(8) Disconnect the jumper lead, timing should advance to 13° B.T.D.C. 4 cylinder models and 15°
B.T.D.C. V6 models. If timing does not advance, perform a self-diagnosis check.

NOTE: If jumper lead is not disconnected, spark advance cannot occur and performance and fuel economy will be severely affected.

(9) Install the plug in the check connector.

Idle Position Switch and Throttle Position Sensor.

(1) Disconnect the TPS harness connector, refer Fig. 47.

(2) Connect an Ohmmeter between terminals 3 and 4, refer Fig. 48.

http://www.sfx-aus.com/e107_images/newspost_images/thumb_48.jpg (http://www.sfx-aus.com/e107_images/newspost_images/48.jpg)

(3) Insert 0.55 mm feeler gauge (4 cyl), 0.65 mm feeler gauge (V6) between the fixed SAS screw and the throttle lever, refer Fig. 49.

http://www.sfx-aus.com/e107_images/newspost_images/thumb_49.jpg (http://www.sfx-aus.com/e107_images/newspost_images/49.jpg)

(4) Loosen the TPS attaching bolts and turn the TPS anti-clockwise, refer Fig. 50.

http://www.sfx-aus.com/e107_images/newspost_images/thumb_50.jpg (http://www.sfx-aus.com/e107_images/newspost_images/50.jpg)

(5) Check for continuity between terminals 3 and 4.

(6) Slowly turn the TPS in a clock-wise direction, refer Fig. 51, until the continuity between terminals 3 and 4 changes to an open circuit. At this position tighten the TPS attaching bolts to the specified torque.

NOTE:
• If the Multi-Use-Tester is used, reconnect the TPS connector and connect the MUT to the diagnosis connector.
• Turn the ignition switch to the ON position, select item No. 14 on the MUT and read TPS output voltage.

(7) Using Special Tool MB991348, connected between the TPS and the TPS harness connector, refer Fig. 52.

(8) Connect a voltmeter between terminal 2 (sensor output) and terminal 4 (sensor ground) of the TPS, refer Fig. 52.

http://www.sfx-aus.com/e107_images/newspost_images/thumb_52.jpg (http://www.sfx-aus.com/e107_images/newspost_images/52.jpg)

(9) Turn the ignition switch to the ON position (do not start the engine).

(10) Check the output voltage of the TPS is 0.4 to 1.0 volts.

(11) If voltage is not to specification check the throttle position sensor and the related harness.

(12) Remove feeler gauge and switch OFF the ignition.

Throttle Stop Screw (Fixed SAS)

CAUTION: The fixed SAS does not require regular adjustment, as it has been precisely set by the manufacturer. If the adjustment has been disturbed, the screw must be adjusted as follows.

(1) Disconnect the accelerator cable.

(2) Loosen the fixed SAS lock nut, refer Fig. 53

http://www.sfx-aus.com/e107_images/newspost_images/thumb_53.jpg (http://www.sfx-aus.com/e107_images/newspost_images/53.jpg)

(3) Back off the screw until it is clear of the throttle valve lever.

(4) Turn the screw in until it just contacts the throttle valve lever, then turn the screw in another 1¼ turns.

(5) Hold the fixed SAS screw in this position and
tighten the lock nut securely.

(6) Reconnect the accelerator cable and adjust if necessary.

Idle Speed

Idle speed adjustment is controlled automatically by the ISC motor system.
The standard idle speed has been adjusted by the speed adjusting screw (SAS), by the manufacturer and there should normally be no need for readjustment.

NOTE: If adjustment is required proceed as follows:—

(1) Confirm that the spark plugs, injectors, idle speed control servo and compression pressures are all normal.

(2) Ensure that the engine is at normal operating temperature, all vehicle lighting and accessories are turned OFF and the transaxle is in Neutral or Park and the ignition timing is adjusted correctly.

(3) If the MUT is used, connect it to the diagnosis plug.

NOTE: When the MUT is used, the diagnosis control terminals are earthed.

(4) If the MUT is not used, use a suitable test lead to bridge terminals 10 and 12 in the self diagnosis connector, refer Fig. 54.

NOTE: Ensure you are bridging the correct terminals, incorrect terminal connections will result in computer failure.

http://www.sfx-aus.com/e107_images/newspost_images/thumb_54.jpg (http://www.sfx-aus.com/e107_images/newspost_images/54.jpg)

(5) Connect a suitable jumper lead to electronic spark advance cut terminal, refer Fig. 55.

http://www.sfx-aus.com/e107_images/newspost_images/thumb_55.jpg (http://www.sfx-aus.com/e107_images/newspost_images/55.jpg)

(6) Start the engine and let it idle.

(7) Check the idle speed is to specification.

NOTE: To connect tachometer, pull back boot on the power transistor connector and inert a suitable probe into the white wire terminal.

NOTE: If the MUT is used, select item No. 22 and read the idle speed.

NOTE: The engine speed may be 20 to 100 rpm lower than specified for a new vehicle (driven
500 km or less), but no adjustment is necessary.

(8) If the idle speed is not to specification, remove the speed adjusting screw sealing cap and turn the SAS
achieve the correct idle speed, refer Fig. 56.

http://www.sfx-aus.com/e107_images/newspost_images/thumb_56.jpg (http://www.sfx-aus.com/e107_images/newspost_images/56.jpg)

NOTE: If the idle speed is higher than specified, even when the SAS is fully closed, check the fixed SAS (Throttle stop screw) to see if it has been moved. If so, adjust the throttle stop screw
as outlined in this section. If not, it is possible that there is a leakage as a result of deterioration of the fast idle air valve (FlAY), and if so, the throttle body should be replaced.

(9) Switch OFF the ignition, remove the jumper wires from the self diagnosis plug, disconnect the
jumper lead from the spark advance cut terminal.

(10) Restart the engine and let it idle for about ten minutes and check the idle speed is to specifications.

Accelerator Cable Inspection and Adjustment for Non auto-cruise control

(1) Ensure the engine is at normal operating temperature.

(2) Turn air conditioner and lights OFF.

(3) Check idle speed is to specification.

(4) Stop engine (ignition switch OFF).

(5) Check that there are no sharp bends in the accelerator cable.

(6) Check accelerator cable for correct freeplay, if not to specification adjust by the following procedure:

A. Turn ignition switch to the ON position (without starting the engine) and leave ignition ON for approx. 15 seconds.

B. Loosen the adjusting bolts and then secure the outer cable so that the freeplay of the inner cable is 1-2 mm Manual Trans. (3-5 mm Auto Trans.)
C. Adjust accelerator cable play and confirm throttle lever stopper touches the fixed SAS screw.

This looks like a great guide!

Forgive my ignorance, but what is this all for?
:think:

To tune your magna to factory spec's

When i was working at Mitsi Dealers most magna's are not set up right because most mechanic's don't worry about setting up base timing, idle speed etc....

Brand new magna's where not checked with Mutt II before beening sold.

Idle Speed
(5) Connect a suitable jumper lead to electronic spark advance cut terminal, refer Fig. 55.Maybe you could clear up for us once and for all how exactly this is done, ie., where should the jumper go to; earth or positive? Any special requirements?

Sorry, just read further up, referring to figure 46, where it says the same thing but states that it goes to earth.
Maybe I can finally make sure my base idle is where it's supposed to be...

Its the round black plug on the left hand side of the fire wall.

:thumbsup: Very good information, :thumbsup:

Will be happier if u post up the same for my V6 TE as well lol

:stoopid: For all third gens would be great!

Nice work mate. Well done..:thumbsup: :D

sooooooooo essentially turning the SAS adjuster screw will change my idle speed. :confused:

Thanks for the info Mitsubishi-Tech. This is good stuff.

Without having to go to a dealer, do you know where I can get my hands on a Mutt?
Do they cost much to buy? Anyone got one they want to sell?

Any chances of getting the pictures back for these procedures?

I'm also interested in viewing the images

If you're looking for a MUT type tool have a look at this one, it works with Gen1 & Gen2 EFI models.

I've seen this and similar ones on ebay for not much $$.

You wouldn't happen to know where/if you can get one that would work with a WindowsMobile based PDA, rather than PalmOS? I'm a bit curious about the interface, a 9-pin connector seems a little strange as the interface for a PDA! :nuts:

EDIT: got it sussed. You need to purchase an additional hotsync cable in order to actually hook it up to a PDA. The 9-pin connector is the standard interface to a PC/laptop. That just makes even less sense in a way, since they are clearly marketing it as a PDA-based device in the first place. ah well...

Early PDAs came with a serial hotsync cable or cradle so probably intended to plug directly to them. Using PalmOS emulator it works on a PC/laptop but does need a PC serial interface which can handle the weirdo MUT data rate. FTDI FT232 usb-rs232 converter works OK.
