Stop light switchConnect a circuit tester to the stop light switch, and check
whether or not there is continuity when the plunger of the’stop
light switch is pushed in and when it is released.
The stop light switch is in good condition if there is no
continuity when the plunger is pushed in to a depth of within 4
mm
(.I6 in.) from the outer case edge surface, and if there is
continuity when it is released.
For vehicles with the auto-cruise control system, the check for
continuity should be made at connectors “a” and “b” of the
stop light switch.

Sub fusible link @
vacuum
w-vStop light
Auto-cruisecontrol unit13A0366Description of operation
When the brake pedal is depressed during constant-speedtravel, the stop light switch’s (NC) contacts for the cruise-control system open, with the result that the current to the
auto-cruise vacuum pump is interrupted, thus canceling the
constant-speed travel.
At the same time, moreover, the closing of the (NO) contacts
for the stop light results in the sending of the cancel signal to
the control unit, so that the auto-cruise vacuum pump current is
discontinued within the control unit, thereby canceling the
constant-speed travel.
The flow of current is from the sub fusible link

The inhibitor switch also functions as the switch for the starter.If the selector lever is moved to the “N” position during

NOTE
1.Each code will be displayed in an order ofpriority beginning from No. 1.
If there is no display, it is possible that
there is a malfunction of the ECU power-
supply circuit or the SET and/or RESUMEswitch, so check according to check
charts
1,2 and 3.
2. Continue each input operation until the
output code is emitted.
If no output codes are emitted for inputs
even though the display pattern is repe-
ated two or more times, there is a
malfunction of the switch sensor.
3.When each input operation is performed and
the signals for the conditions are received by
the computer, each output code will be
repeatedly displayed in the sequence of
priority for as long as that signal continues.
4.If, during the display of output codes, the
input operation is canceled (if, for example,
the SET switch is set from ON to OFF), the
code will be displayed for one cycle of the
display, but will not be displayed during the
next cycle.
This makes it possible, therefore, to check
the OFF condition (existence of not of a
short-circuit of the input line or the switch).
