(c) If continuity is OK between cavity 62 and
cavity 1, repair open circuit between cavity 2 of the
stop lamp switch connector and ground.
(6) Using an ohmmeter, check continuity from cav-
ity 76 on PCM connector to ground with the trans-
mission in park or neutral. If no continuity, test TRS/
Park-Neutral switch and switch wiring
(7) Turn speed control and ignition switch OFF.
(8) Unplug the BLACK 40-way connector from the
Powertrain Control Module (PCM)
(9) Using an ohmmeter, check continuity from cav-
ity 3 of servo connector to cavity 5 on the PCM con-
nector.
(a) If continuity is OK, replace PCM. Check cir-
cuit for short to ground before replacing PCM.
(b) If no continuity, remove stop lamp switch
and conduct Stop Lamp Switch Test. If test fails,
adjust or replace as necessary.
(c) If switch passes, measure continuity from
cavity 4 of stop lamp switch connector to cavity 3
of servo connector. Repair open circuit if necessary.
(d) If continuity is OK, measure continuity from
cavity 3 of stop lamp switch to cavity 5 of PCM
connector. Repair open circuit as necessary.
(e) Install PCM connectors onto PCM and speed
control servo connector to servo.
VACUUM SUPPLY TEST
(1) Disconnect vacuum hose at the servo and
install a vacuum gauge in the hose (Fig. 9).
(2) Start engine and observe gauge at idle. Vac-
uum gauge should read at least ten inches of mer-
cury. Shut off engine, the vacuum should continue to
hold 10 inches of mercury.
(3) If vacuum does not meet this requirement,
check and correct the following vacuum leaks in the
vacuum lines, check valve, vacuum reservoir or poor
engine performance.
VEHICLE SPEED SENSOR
For diagnosis and testing of the Vehicle Speed Sen-
sor (VSS), refer to the appropriate Powertrain Diag-
nostic Procedures service manual. Also refer to the
DRB scan tool.

GENERAL INFORMATION
INTRODUCTION
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAG, SEE GROUP 8M, RESTRAINT SYSTEMS FOR
AIRBAG REMOVAL PROCEDURES.
The turn signals are part of the multi-function
switch. Which contains:
²Electrical circuitry for turn signals
²Hazard warning switch
²Headlamp beam select switch
²Headlamp optical horn
The integrated switch assembly is mounted to the
left hand side of the steering column. When the
driver wishes to signal his intentions to change direc-
tion of travel, he moves the lever upward to cause
the right signals to flash and downward to cause the
left signals to flash. After completion of a turn the
system is deactivated automatically. As the steering
wheel returns to the straight ahead position, a can-
celing cam molded to the clockspring mechanism
comes in contact with the cancel actuator on the turn
signal multi-function switch assembly. The cam lobe,
pushing on the cancel actuator, returns the switch to
the off position.
If only momentary signaling such as indication of a
lane change is desired, the switch is actuated to a
left or right intermediate detent position. In this
position the signal lamps flash as described above,
but the switch returns to the OFF position as soon as
the lever is released.
When the system is activated, one of two indicator
lamps mounted in the instrument cluster flashes in
unison with the turn signal lamps, indicating to the
driver that the system is operating.
DESCRIPTION AND OPERATION
HAZARD WARNING SYSTEM
The hazard warning system is actuated by a slide
button located on the top of the steering column
between the steering wheel and the instrument
panel. The hazard switch is identified with a double
triangle on front of the button.
COMBINATION FLASHER
The turn signal flasher and the hazard warning
flasher are combined into one unit called a combina-
tion flasher (combo-flasher). The combo- flasher con-
trols the flashing of the hazard warning system and
the turn signal system. An inoperative bulb or incom-
plete turn signal circuit will cause the flasher rate to
double.
The combo-flasher is located on the fuse block. The
combo-flasher is black in color for ease of identifica-
tion (Fig. 1).

DIAGNOSIS AND TESTING
MULTI-FUNCTION SWITCH
The multi-function switch contains electrical cir-
cuitry for turn signal, hazard warning, headlamp
beam select, headlamp optical horn. This integratedswitch assembly is mounted to the left hand side of
the steering column. Should any function of the
switch fail, the entire switch assembly must be
replaced. Refer to Multi-function Switch Test Table
