DESCRIPTION
The ABS control module monitors the voltage at the positive (+) terminal of each sensor while the ignition switch
is ON. When the voltage is not within the specified range, an applicable DTC will be set. Also, when no sensor signal
is inputted at starting or while running, an applicable DTC will be set.
NOTE:
When the vehicle was operated in any of the following ways, one of these DTC's may be set even when
the sensor is in good condition. If such possibility is suspected, repair the trouble (dragging of brake, etc.)
of the vehicle, clear DTC once and then after performing the driving test as described in Step 2 of ªABS
DIAG. FLOW TABLEº, check whether or not any abnormality exists.
± The vehicle was driven with parking brake pulled.
± The vehicle was driven with brake dragging.
± Wheel spin occurred while driving.
± Wheel(s) was turned while the vehicle was jacked up.
± The vehicle was stuck.

As the aluminum case is sealed with liquid type gas-
ket, it is necessary to use genuine sealant or its equiv-
alent on its mating surfaces when reassembling it.
Also, the case fastening bolts must be tightened to
specified torque by means of the torque wrench and
tightening over or below the specified torque should
be avoided.
The description under ON-VEHICLE SERVICE in this
section covers a part of the TYPE 2 manual transmis-
sion and the transfer. The transfer is next to the trans-
mission as well, but their gear boxes are independent
and each of them has its own drain and level / filler
plugs for the oil change or the level check.
For the repair procedure of the transfer unit, refer to
Section 7D.

GENERAL DESCRIPTION
The manual transmission consists of the input shaft,
main shaft, countershaft and reverse gear which are
installed in the aluminum case. Its gears are of for-
ward five speeds in synchro mesh and reverse one
speed in constant mesh system.
The main shaft gears are held by the needle bearings
and on them the synchronizer rings and synchronizer
sleeve & hubs are assembled.
The gear shift lever case is located at the upper be-
hind the transmission case and has a cam which pre-
vents direct gear shift from the 5th speed gear to the
reverse gear.

The manual transmission consists of the input shaft,

installed in the aluminum and castings cases. Its
gears are of forward five speeds in synchro mesh and
reverse one speed in sliding idler gear arrangement
system.
The main shaft gears are held by the needle bear-

chronizer sleeve & hubs are assembled.
The gear shift lever case is located at the upper be-

GENERAL DESCRIPTION
This automatic transmission is a full automatic type with 3-speed plus overdrive (O / D).
The torque converter is a 3-element, 1-step and 2-phase type and is equipped with an electronically controlled
lock-up mechanism. The gear shift device consists of 3 sets of planetary gear units, 3 disc type clutches, 4 disc
type brakes and 3 one-way clutches. The gear shift is done by selecting one of 6 positions (ªPº, ªRº, ªNº, ªDº, ª2º
and ªLº) by means of the select lever installed on the floor. On the shift knob, there is an overdrive (O / D) cut switch
which allows shift-up to the overdrive mode (except at 4L) and shift-down from the overdrive mode. Also, by using
the P / N change switch located on the console box, it is possible to select the gear change timing of 2 modes, nor-
mal and power.
