CLOCK
Troubleshooting
CLOCK WILL NOT OPERATE
Check amount of time the clock loses or gains per day or a week against the allowable error table.
Check to see if there is 11 ± 15V
on terminal6 of connector on clock side.
Check to see if clock adjust-
ing button is sticking i n posi-
tion and has failed to return.
Check to see if there is volt-
age at terminal B or connec-
tor or clock side.
Check to see if clock ground
wire is loose or rusted.Check to see if battery voltage
is over 11 V with no load.Repair if necessary or re-
place clock. Locate trouble and repair or re-
place fuse as necessary.
Locate cause and repair,
or recharge battery. Check to see if connector on
clock side is loose or rusted.

1. INSPECT ALLOWABLE ERROR OF CLOCK
Check the allowable error of the clock.
Allowable error (per day):
+ 1.5 seconds
2. ADJUSTMENT OF CLOCK
Adjustment of the quartz clock requires a precise digital
counter. Adjustment must be made in shop specified by-
the manufacturer.
3. SETTING OF CLOCK
(a) Connect the battery terminal.
(b) Check the clock to see that it is running, and then set
it to the correct time.
HINT: Whenever the battery terminal is disconnected,
make sure to set the clock to the correct time after reco
necting the battery.

Diagnosis System
OUTPUT OF DIAGNOSTIC CODES
1. READ TYPE A CODE
(a) Turn the ignition switch on.
(b) Turn the set/coast switch on, and keep it on.
(e) Push the main switch on.
(d) Turn the set/coast switch oft.
(e) Meet the conditions listed below.
(f) Read the diagnostic code on the main switch indica-
tor.
HINT:
wTo save time performing the next test, do not turn off the
ignition switch when steps (a) ± (f) are completed.
wChecking of No. 4 code is done with the vehicle jacked
up and the engine idling.
wIf there is no indication code, perform diagnosis ±and
inspection. (See page Be±74)

2. READ TYPE 6 CODE
(a) If while driving with the cruise control on, the system is
cancelled by a malfunction in either the actuator, speed
sensor, or control switch circuit, the main switch indicator
will blink 5 times.
(b) While driving at a speed of 16 km/h (10 mph) or less,
press the SET/COAST switch three times in two
seconds.
HINT: In order to retain the diagnostic code when a ma
function has occurred, always inspect with the ignition
and main switches on.
Should the power be cut, the diagnostic code will be
erased from the computer memory.
(e) Read the diagnostic code on the main switch indicator.
HINT:
wIndication codes appear in order from No. 11.
wIndication is stopped when vehicle speed is over 16
km/h (10 mph) or main switch is turned off.
wIf there is no indication code, perform diagnosis and in-
spection. (See page BE±74)
* If the set speed can be maintained when the speed control switch is again set at SET/COAST, there is no malfunction.*Vehicle speed decreases to 16 km/h (14 mph)
or more below set speed.

Setting speed does not cancel when shifted to ºNº
range (A/T only).Setting speed does not cancel when parking brake
pulled up.Vehicle speed does not decrease when coast switch
turned on.
Setting speed does not cancel when clutch pedal
depressed (M/T only).Vehicle speed does not return to memorized speed
when resume switch turned on.
Setting speed does not cancel when brake pedal
depressed.Vehicle speed fluctuates when set switch turned on.
Cruise control will not disengage even about
40 km/h (25 mph).Vehicle speed does not accelerate when accel
switch turned on.
A short period after the O/D cut, (Approx.
within 14 seconds) the O/D wilt resume. Speed can be set below about 40 km/h (25 mph).Inspect No.5 of type A code.
Inspect No.6 of type A code. Return and acceleration response is sluggish.
