Starting System – V6 Page 6D1-2–3

1 General Information
All HFV6 engines are fitted with a Mitsubishi starter motor. This consists of a solenoid switch on a DC motor. The motor
has permanent magnet excitation, which has the advantage of low weight a with high output torque and is visually
identifiable by the absence of pole-shoe retaining screws.
The starter motor does not have field coil windings or pole shoes. These parts have been replaced by six permanent
magnets that are held in the pole housing by clips. The positive brushes are now part of the brush plate assembly.
The solenoid switch is the only component of the starter motor assembly that is serviced separately. If any other parts
require replacement, the starter motor must be replaced.

2 Safety Precautions

• Battery fluid contains sulphuric acid,
which can cause serious injury. Do not
allow liquid from the battery to contact
eyes or skin. If contact occurs, flush the
area immediately with running water and
contact a physician.
• Lead acid batteries produce explosive
gases. Keep sparks, flames and lighted
cigarettes away from the battery,
especially when the battery is being
charged. Failure to follow this warning
could result in a battery explosion.
• Metal objects that touch a battery terminal
can produce sparks that can cause
serious burns. When working near a
battery, take extra care with metal objects
including tools and items of jewellery,
especially rings and metal watchbands.

Do not allow liquid from the battery to contact
clothing or painted surfaces. If contact occurs,
flush the area immediately with running water.
W hen working with or near the battery, always:
• W ear safety glasses and work gloves.
• Remove items of jewellery such as rings and metal watchbands.
• Ensure the ignition is switched off when connecting or disconnecting battery cables, battery charging equipment or
battery jumper cables. Failing to do so can damage the vehicle electronic components.
• Disconnect the negative battery cable before disconnecting the positive cable from the battery. Inversely, connect
the positive battery cable to the battery before connecting the negative cable. This reduces the possibility of
shorting the battery to ground while working near the positive connections.

TRANSMISSION CONTROL SYSTEM (AW30–40LE) 7A2-13
Item Description
Reverse lock out control If the select lever is moved to "R" position during forward driving, the TCM prohibits
reverse driving by turn off the S1 and turn on the S2 for prevention of danger and
protection of the automatic transmission.
1. Enable condition a) Vehicle speed is more than 11km/h (7mph).
2. Disable condition a) Vehicle speed is less than 9km/h (6mph).
b) W hen except "R" position is detected.
Auto cruise mode control If the auto cruise control can’t keep the setting speed like a uphill driving, the TCM selects the auto cruise mode shift pattern for downshifting, thus keeping the vehicle
speed.
W arm-up mode control TCM selects the warm-up mode shift pattern in engine cold condition for improvement of drivability and facilitation of warm-up.
Squat control W hen the TCM detects N→D garage shift, the TCM controls 1-3-1 shift by setting
timer, in order to improve the shift feel at N →D.
Coast down control The TCM switches to the coast down control at the coasting, in order to reduce the
roughness of shifting.
Uphill control W hen the TCM detected uphill, the TCM automatically switches to the uphill mode
in two-stage in proportion to inclination pitch to prevent the busy shifting and to
obtain an enough torque.
Downhill control W hen the TCM detected downhill, the TCM automatically switches to the downhill
mode, and shifts to the 3rd or keeps in the 3rd in order to prevent the vehicle
acceleration. Then, the brake load is reduced by a moderate engine brake and fuel
consumption is improved by the fuel cut.
Line pressure control The TCM controls the impressed current of the pressure control solenoid based on the throttle opening, and regulates suitable throttle pressure.
Engine truque management
control The TCM controls engine torque for improvement of shift quality or durability under
the following conditions.
• Upshift and downshift
• Garageshift
Indicate driving mode function The TCM indicates the following driving mode on instrument panel.
• Power mode
• 3rd start mode
Indicate oil temperature
warning function If the transmission oil temperature sensor senses that transmission oil temperature
is greater than 146 °C (295 °F) , the TCM turns on ATF warning lamp. (The warning
lamp is turned off, if oil temperature is less than 126 °C/ 259 °F .)
Fail-safe function W hen trouble occurs to vehicle sensor and each solenoid, TCM automatically exerts
fail-safe control not to spoil driveability.
• This control is exerted when sensor or actuator is in trouble, while TCM works
normally.
• The "CHECK TRANS" light flashes to alert the driver, and the transmission
must be manually shifted as follows.

Select lever position Gear position
D 4 (Fourth)
3 4 (Fourth)
2 3 (Third)
L 3 (Third)
R Reverse
Shift are firmer to prevent clutch slip and consequent wear. The fault should be
corrected as soon as possible.

Diagnostic Trouble Codes
The purpose of the “Diagnostic Trouble Codes” mode is
to display stored TCM trouble codes.
W hen “Diagnostic Trouble Codes” is selected an
“Application Menu” screen appears.
Read DTC Information
W hen “Read DTC Information” is selected, an
“Application Menu” appears with a list of DTC
information function keys addressing DTC specifics and
their origins.
Function key selections may vary for particular vehicle
and/or system.
Requested emission-related DTCs
Clear DTC Information
The purpose of the “Clear DTC Information” mode is to
command the clearing of stored TCM trouble codes.
W hen “Clear DTC Information” is selected, a “Clea
r
DTC Information”, warning screen appears. This screen
informs you that by cleaning DTC's, “all stored DTC
information in controller will be erased”.
Do you want to clear DTC's (Yes/No).
Press either the Yes or No key when answering.
After clearing codes, confirm system operation by test-
driving the vehicle.
Allow the vehicle to shift through all four forward gears
in a manner which attempts to repeat the failure
condition.
NOTE: W hen the trouble has not been repaired and
the trouble code cannot be erased, check the vehicle
again.
Data Display
The purpose of the “Data Display” mode is to
continuously monitor data parameters.
The current actual values of all important sensors and
signals in the system are displayed through F1 mode.
W hen “Data Display” is selected an “Application Menu”
appears. “Transmission Data Display”.
See “Transmission Data” on next page.
Snapshot
W hen “Snapshot” is selected an “Application Menu”
appears.
W hen “Transmission Snapshot” application is selected
from the “Application Menu”, a “Snapshot Menu”
appears, displaying several options. “Snapshot” options
may vary from one system to another.
“Snapshot” allows a recording of all vehicle parameters.
There parameters may then be replayed at a future
point in time.

This action allows you to focus on making the condition
occur, rather than trying to view all of the data in
anticipation of the fault. The snapshot will collect
parameter information around a trigger point that you
select.
W hen a snapshot is taken, it is recorded onto the
PCMCIA memory card. W hen the Tech 2 is powered
down. Snapshots are not lost.
Actuator Test
The purpose of “Actuator Test” mode is to check fo
r
correct operation of electronic system actuators.
Solenoid 2-3 Test, Solenoid 1-2/3-4 and Test TCC
Solenoid Test
You can operate the solenoids by pressing the “ON”
and “OFF” buttons.
Preconditions: P–N position, no vehicle speed, no
engine speed
Pressure Control Solenoid (PCS)
You can set desired PCS Current using the “ON” and
“OFF” button. The PCS Data informs about PCS
Current, Pressure and Duty Cycle.
Preconditions: P–N position, no engine speed, no
vehicle speed
3rd Start Lamp Test, Power Lamp Test, AT Oil
Temperature Lamp Test and Check Light Test
You can operate the lamps by pressing the “ON” and
“OFF” buttons.
Preconditions: none
NOTE: Freeze Frame
Freeze Frame is an element of the Diagnostic
Management System which stores various vehicle
information at the moment an emission-related fault
is stored in memory and when the Check Trans
Lamp is commanded on. These data can help to
identity the cause of a fault. Refer to Storing An
d
Erasing Freeze Frame Data for more detaile
