Malfunction Indicator Lamp (MIL) Check
Refer to the same item in Section 6-1 for checking procedure.
“O/D OFF” Lamp Check
1) Check that O/D off switch button is at OFF position (pushed).
2) Turn ignition switch ON.
3) Check that “O/D OFF” lamp lights for about 2 – 4 sec. and
then goes OFF.
If anything faulty is found, advance “DIAGNOSTIC FLOW
TABLE B-1 or B-2 “O/D OFF” LAMP CIRCUIT CHECK”.
“POWER” Lamp Check
1) Check that Power/Normal change switch button is at Normal
position.
2) Turn ignition switch ON.
3) Check that “POWER” lamp lights for about 2 – 4 sec. and
then goes OFF.
If anything faulty is found, advance “DIAGNOSTIC FLOW
TABLE B-3 or B-4 “POWER” LAMP CIRCUIT CHECK”.
Diagnostic Trouble Code (DTC) Check
Refer to the same item in Section 6-1 for checking procedure.
Diagnostic Trouble Code Clearance
Refer to the same item in Section 6-1 for clearance procedure.

TROUBLESHOOTING
[A] for Step 1/[B] for Step 4Step Action Yes No
1 Check Power/Normal change switch position.
Is switch button at Normal position?Go to Step 2. Set Power/Normal
change switch at Nor-
mal position.
2 Check lamp circuit for short.
1) Turn ignition switch OFF and disconnect PCM
connectors.
2) Turn ignition switch ON.
Does “POWER” lamp come ON steadily?“GRY/BLU” circuit
shorted to ground.Go to Step 3.
3 Check Power/Normal change switch circuit.
1) Check resistance between terminal E61-31 of dis-
connected PCM connector and body ground with
P/N change switch OFF.
Is continuity indicated?Go to Step 4. Check PCM ground
circuit for open.
If ground circuit is OK,
substitute a known-
good PCM and
recheck.
4 Check Power/Normal change switch for operation.
1) Remove Power/Normal change switch.
2) Check continuity between switch terminals “4” and
“5” under each condition below.
Normal position: No continuity
Power position: Continuity.
Is check result satisfactory?“ORN/BLU” circuit
shorted to ground.Replace Power/Normal
change switch.

8E-4 CRUISE CONTROL SYSTEM
Components and functions
Component Function
Cruise control actuator
assembly with control mod-
uleCruise control module:
Executes centralized control by means of a microcomputer over all functions
including setting a constant speed, resuming it, setting coast, limiting minimum
speed and cancelling cruise control.
Cruise control actuator (stepping motor & clutch) :
Actuates accelerator pedal through cruise cable and arm according to a signal
from cruise control module to control vehicle speed.
Cruise main switch This switch has a momentary contact type button to turn the cruise control
system ON and OFF.
SET COAST switch When this switch is rotated (ON) and then released (OFF) while vehicle is run-
ning at a speed 40 km/h (25 mile/h) or higher, vehicle speed at that OFF
moment is stored in memory and it is maintained (constant cruising).
Rotating this switch (ON) continuously during constant cruising keeps slowing
down vehicle speed as long as it is ON. When it is released (OFF), vehicle
speed at that moment is stored in memory and vehicle starts constant cruising.
ACCEL RESUME switch When this switch is rotated (ON) during constant cruising, vehicle speed keeps
increasing as long as it is ON. When it is released (OFF), vehicle speed at that
moment is stored in memory and vehicle starts constant cruising. If vehicle
speed is higher than 40 km/h (25 mile/h) after cruise control is cancelled, turn-
ing this switch ON momentarily will resume the speed at which vehicle was run-
ning before cancellation.
CANCEL switch When this switch is pressed (ON), cruise control (accelerator pedal control) is
cancelled.
Vehicle speed sensor (VSS) The vehicle speed sensor (VSS) is mounted on the transfer or transmission.
The VSS converts vehicle speed into pulse signal and send it to the cruise con-
trol module.
Stop lamp switch The stop lamp switch has 2 contact points. One contact point closes when the
brake pedal is depressed to light the stop lamp and provides a voltage signal to
the cruise control module. This signal, when inputted cancels cruise control
(sets the accelerator pedal free).
The other contact point (brake pedal position switch) opens when the brake
pedal is depressed, to shut off the power to the magnetic clutch in the actuator,
thereby cancelling cruise control (setting the accelerator pedal free).
This switch is installed to cancel cruise control (constant cruising) without fail.
Clutch pedal position switch
(M/T vehicle only)When the clutch pedal is depressed, the clutch pedal position switch closes and
provides a ground signal to cruise control module.
The cruise control module cancels cruise control (accelerator pedal control)
when this signal is inputted.
Transmission range switch
(Park/Neutral position switch)
(A/T vehicle only)When the selector lever is places in either “P” or “N” position, the transmission
range switch closes and provides a ground signal to cruise control module. The
cruise control module cancels cruise control (accelerator pedal control) when
this signal is inputted.
PCM – Throttle opening sig-
nal (4 A/T vehicle only)Throttle opening signal is inputted from PCM.
From this signal, the cruise control module detects the throttle opening and
uses it as one of the factors to output the overdrive and TCC OFF command sig-
nal to PCM.
