1.Description:
There have been cases where the troubles failed to be removed completely because of incorrect
balancer machine handling or use of an inaccurately calibrated balancer machine. This Service
Bulletin informs you of the cautions to be taken when handling a balancer machine and the
balance check procedures to prevent such a case from recurring in a dealer.
2.Details:
To solve the problems caused by steering or body vibrations, it is essential to balance the wheels
and tires accurately. For this, the wheel and tire must be accurately centered with respect to the
balancer shaft, and the balancer must also be calibrated accurately.

Caution:
The socket diameter of a Mitsubishi genuine wheel is

matching the socket diameter.
Use the black-mounted cone to secure the wheel to the balancer if possible. If installable i

this method, go to Step 4.
If the socket diameter of the wheel is too large to secure it with the back-mounted cone,
•
secure the wheel to the balancer with the front mounting cone. If the wheel is to be secured in
this way, go to Step 6.
Do not use the log nut hole mounting method because it does not allow the accurat

centering of the wheel.
4. When securing with back-mounted cone:
Operate the balancer to measure the imbalance, an attach weight in accordance with the
measurements.
Caution: Be sure to drive the weight straight in the wheel.

5. Loosen the wing nut, rotate the wheel half a turn (180°) and tighten the nut again. Then, perform the
measurement again to confirm that the wheel is in balance. If not in balance, check if the balancer is
correctly calibrated. Go to Step 11.

6. When securing with front-mounted cone:
Caution:
When pressing in the cone by tightening the wing nut slowly, hold the tire by hand such that
•
the wheel may contact the spring plate of the balancer evenly.
If this work is not performed with care, the wheel would fail to be centered correctly.
•
Futhermore, the cone-contacting area of the wheel would deform, preventing subsequent
wheel balancing from being performed accurately.
Operate the balancer to measure the imbalance. Mark the point attributable to the imbalance with a
piece of chalk.
(Do not attach any balance weight.)

7. Loosen the wing nut, rotate the wheel half a turn (180°) and tighten the wing nut carefully again. Then,
perform the measurement again.
8. Repeat the measurement three times in the same manner, and take either of the following measures
according to the measurement again.
Caution: Be sure to drive the weight straight in the wheel.
If the results are the same in all measurements, attach a weight according to the indication on th

b. If the weight difference among the three measurements is less than 0.5 oz and the thre indicated
points are all within a range of less than 8 inch (30°), attach a weight having the average weight at
the mean position.
c. If the weight difference among the three measurements is 0.5 oz or more or if the indicate
positions are not within a range of less than 8 inch (30°), check if th balancer is correctly calibrated.
Go to step 11.

11. Checking for calibration.
Check your balancer’s calibration approximately every 100 balances. Your whee balancer’s instruction
manual should include calibration procedures. If the calibration procedures specifically for your balancer
are missing, use following steps for zero calibration, static balance, and dynamic balance checks. Th
wheel balancer calibration checks are also described in the flowchart on next page.
a. Mount an undamaged original-equipment alloy rim and tire assembly (wheel) onto your off-the-car
wheel balancer. Balance the wheel.
b.
Zero Calibration Check.
Loosen the balancer wing nut, rotate the wheel a half-turn (180°), and
retighten the nut. Recheck the balance.
i)
If the imbalance is 5 grams or less, the zero calibration is OK. Rebalance the wheel, then g
to Step d to check the static balance.
ii)
If the imbalance is more than 5 grams, go to Step c.
c. Loosen th balancer wing nut, rotate the wheel ¼ turn (90°), and retighten the nut. Recheck th
wheel balance
i)
If the imbalance is 5 grams or less, the wheel may not be centered on th balancer, or the
balancing cones, the cup, and/or wing nut are damaged, dirty, or inappropriate for the wheel.
You may need to refer to th balancer manufacturer’s instructions to verify the correct
attachments. After making the necessary correction, recheck the wheel balance. If OK, then
go to Step d.
ii)
If the imbalance is more than 5 grams, th balancer requires calibration, Contact th balancer
manufacturer for calibration by their repair representative.
d.
Static Balance Check.
Attach a 5-gram weight to the outer rim. Recheck the balancer. The
balancer should detect 5±2 grams of imbalance 170° to190° away from the 5-gram weight.
i)
If the imbalance is within specification, the static balance calibration is correct, Go to Step e
to check the dynamic balance.
ii)
If the imbalance is out of specification, th balancer requires calibration. Contact th balancer
manufacturer for calibration by their repair representative.
e.
Dynamic Balance Check.
Attach a 5-gram weight to the inner rim at 180° opposite the 5-gram
weight that was added in Step d. Recheck the balance. Th balancer should detect 5±2 grams of
imbalance 170° to 190° away from both the inner and outer 5-gram weights.
i)
If the imbalance is within specification, the dynamic balance calibration is correct. Th
balancer calibration checks are complete.
ii)
If the imbalance is out of specification, th balancer requires calibration. Contact th balancer
manufacturer for calibration by their repair representative.

4. Remedy the malfunctions indicated by th
diagnosis codes, disconnect the diagnosis code
check harness, and then install the valve relay.
Then turn the ignition switch to ON again t
check the ABS warning lamp. (Refer to P.35-36-
16.) If the lamp indicates a malfunction, th
valve relay system may be detective. (Refer to
P.35-36-14.)
ERASING DIAGNOSIS CODES
<Old>
With the MUT-II
Connect the MUT-II to the diagnosis connector (16pin), and then erase the diagnosis codes.
>
35-36-4
Without the MUT-II
Remove the battery cable from the battery (-)
terminal for 10 seconds or more, and the
reconnect the cable.
<New> See next page.
5
<New>
With the MUT-II
Connect the MUT-II to the diagnosis connector (16-pin), then erase the diagnosis codes.
Caution
Turn the ignition switch off before connecting or disconnecting the MUT-II.
When diagnostic trouble codes (Nos. 21 to 24) (for vehicle wheel speed sensor system failures) occur,
normal MUT-II operation may not erase those codes. In that case, erase the diagnostic trouble codes
using the following procedures.
1. Perform erasing of the diagnostic trouble codes by special operation of the brake pedal. (See erasing
procedure for the diagnostic trouble codes without use of the MUT-II.)
2. Turn the ignition switch OFF.
3. Perform erasing of the diagnostic trouble codes by use of the MUT-II.
Without the MUT-II
1. Stop the car.
2. Place the stop lamp switch to ON (with brake pedal depressed).
3. Under the condition of 1 and 2 above, turn the ignition switch ON. After that, place the stop lamp
switch to OFF (with brake pedal released) within 3 seconds, and cycle the stop lamp switch ON and
OFF ten times consecutively.
NOTE:
When ABS-ECU stops functioning through the fail-safe mechanism, erasing of the diagnostic troubl
codes cannot be performed.
