[!) 1.
Fig. 8-148
With the switch
installed to the transmission,
check the continuity between the
terminals of
the switch connectors.
When the continuity is found between the
terminals only with the switch shifted to the
reverse position, the switch
is normal.
2. When the result of the above inspection is
found abnormal, remove the switch from
the transmission and conduct a test on the
switch
alone.
If
the continuity appears between the con­
nector
terminals when the ball of the switch is
released, the switch is normal. (When the ball
is pushed, the continuity disappears.)
3. If there is no continuity with the switch
installed to the transmission, even though
the switch is found to be normal, then adjust
the stroke
of the switch by changing the
thickness
of the switch gasket.

8-192 CHASSIS ELECTRICAL
TRANSMISSION CONTROL MODULE (TCM)
GENERAL DESCRIPTION
The circuit consists of the starter switch, TCM, mode switch, brake switch, speed sensor, kick down switch,
Power and
Winter switches, Throttle Position (TP) sensor, Engine Control Module (ECM), barometer sensor,
adapter case, main case,
warning light (CHECK TRANS, NT OIL TEMP) and indicator light (WINTER DRIVE,
POWER DRIVE).
The TCM, based on the predetermined shifting characteristics and lockup operating valve, provides the
optimum shifting control to the varying vehicle running condition. The following input signals are sent to the
TCM: select lever position from the mode switch, running mode from the POWER & WINTER switches,
throttle opening from the TP sensor, vehicle speed from the vehicle speed sensor and engine speed from the
ECM are sent to the TCM. After receiving these signals, the TCM determines the vehicle running condition,
and
it sends output signals to each solenoid to control shifting.
When the
TCC solenoid is engaged, the lockup mechanism operates.
The shift
solenoid 2.3 and 1.2/3.4 selects the shift gear position.
The force
motor controls the line pressure to improve shifting.
Also, when the TCM detects an abnormal signal from the transmission or sensor, it will cause the "CHECK
TRANS"
light on the warning box to flash in order to inform the driver of the malfunction.
Refer to section 7 A "AUTOMATIC TRANSMISSION" for details.
