B: ON-BOARD DIAGNOSIS WITH SELECT
MONITOR
1. GENERAL
The on-board diagnosis function of the cruise control sys-
tem uses an external select monitor.
The on-board diagnosis function operates in two
categories, which are used depending on the type of prob-
lems;
Cruise cancel conditions diagnosis
Real-time diagnosis
Applicable cartridge No.: 498349601
Cruise cancel conditions diagnosis
This category of diagnosis requires actual vehicle driv-
ing in order to determine the cause, (as when cruise
speed is cancelled during driving although cruise cancel
condition is not entered).
Cruise control module memory stores the cancel condi-
tion (Code No.) which occurred during driving. When
there are plural cancel conditions (Code No.), they are
shown in order, for 2 seconds per Code No., on the
select monitor.
CAUTION:
The cruise control memory stores not only the
cruise“cancel”which occurred (although“cancel”
operation is not entered by the driver), but also the
“cancel”condition input by the driver.
The content of memory is cleared when ignition
switch or cruise main switch is turned OFF.
Real-time diagnosis
The real-time diagnosis function is used to determine
whether or not the input of output signal system is in good
order, according to signal emitted from switches, sensors,
etc.
Vehicle cannot be driven at cruise speed because prob-
lems occurs in the cruise control system or its associ-
ated circuits.
Monitor the signal conditions from switches and sen-
sors.

2. CRUISE CANCEL CONDITIONS DIAGNOSIS
1) Connect select monitor.
2) Start the engine and turn cruise control main switch to
ON.
3) Set select monitor in“FB0”mode.
4) Drive vehicle at least 40 km/h (25 MPH) with cruise
speed set.
5) If cruise speed is canceled itself (without doing any
cancel operations), a trouble code will appear on select
monitor display.
CAUTION:
A trouble code will also appear when cruise cancel
is effected by driver. Do not confuse.
Have a co-worker ride in vehicle to assist in diagno-
sis during driving.
NOTE:
Trouble code will be cleared by turning ignition switch or
cruise control main switch to OFF.
3. REAL-TIME DIAGNOSIS
1) Connect select monitor.
2) Turn ignition switch and cruise control main switch to
ON.
3) Set select monitor in“FA 0”mode.
4) Ensure that normal indication is displayed when con-
trols are operated as indicated below:
When SET/COAST switch is pressed.
When RESUME/ACCEL switch is pressed.
When brake pedal is depressed. (Stop and brake switch
turns ON.)
When clutch pedal is depressed. (MT model)
When select lever is set to N position. (AT model)

C: CHECK CRUISE CONTROL MAIN SWITCH
DIAGNOSIS:
Faulty cruise control main switch, or open harness.
TROUBLE SYMPTOM:
Cruise control main switch is not turned ON and cruise
control cannot be set.
NOTE:
When the main relay (built-in cruise control module)
operates, the main switch circuit is in normal condition.
The main relay operation can be checked by hearing the
operation sounds.
This operation sounds will be heard when ignition switch
and cruise control main switch is turned to ON.
1. Check fuse and power supply.
OK
Not OK
Melted fuse,repair the shorted part of the circuit.
,replace fuse.
2. Check cruise control main switch.
OK
Not OK
Open harness,repair faulty main switch.,
replace.
3. Check harness connector between cruise
control main switch and cruise control
module.
OK
Not OK
Repair or replace wiring harness.
