STEP 8. Check the harness wire between stoplight switch
connector C-03 and intermediate connector C-89.
Q: Is any harness wire between stoplight switch connector
C-03 and intermediate connector C-89 damaged?
YES : Repair the harness wire and then check that the
malfunction is eliminated.
NO : Check that the malfunction is eliminated.
If the malfunction is eliminated, replace the auto-
cruise control-ECU. (Refer to
.)
Then check that the malfunction is eliminated.
STEP 9. Check the output circuit voltage at auto-cruise
control-ECU connector C-20 by backprobing.
(1) Do not disconnect auto-cruise control switch connector C-
20.
(2) Turn the ignition switch to "ON" position.
(3) Measure the voltage between terminal 4 and ground by
backprobing.
•
Voltage should be battery positive volts.
(When brake pedal is depressed.)
•
Voltage should be 0.5 volts or less.
(When brake pedal is not depressed.)
(4) Turn the ignition switch to "LOCK" (OFF) position.
Q: Is the voltage within specifications?
YES : Check that the malfunction is eliminated.
If the malfunction is eliminated, replace the auto-
cruise control-ECU. (Refer to
.)
Then check that the malfunction is eliminated.
NO : Go to Step 10.

STEP 10. Check auto-cruise control-ECU connector C-20
and intermediate connector C-89.
Q: Is the connector damaged?
YES : Repair or replace connector.
Refer to GROUP 00E, Harness Connector Inspection
.
Then check that the malfunction is eliminated.
NO : Go to Step 11.
STEP 11. Check the harness wire between intermediate
connector C-89 and auto-cruise control-ECU connector C-
20.
Q: Is any harness wire between intermediate connector C-
89 and auto-cruise control-ECU connector C-20
damaged?
YES : Repair the harness wire and then check that the
malfunction is eliminated.
NO : Check that the malfunction is eliminated.
If the malfunction is eliminated, replace the auto-
cruise control-ECU. (Refer to
.)
Then check that the malfunction is eliminated.

CIRCUIT OPERATION
This circuit indicates the operation status of the
clutch pedal position switch. When the clutch pedal
position switch is ON (clutch pedal is depressed), the
voltage of auto-cruise control-ECU terminal number
13 will indicate 0 volt.
TECHNICAL DESCRIPTION (COMMENT)
The cause is probably a malfunction of the clutch
pedal position switch circuit.
TROUBLESHOOTING HINTS
•
Malfunction of the clutch pedal position switch.
•
Damaged harness or connector.
•
Malfunction of the auto-cruise control-ECU.
DIAGNOSIS
STEP 1. Check the clutch pedal position switch.
1.Disconnect clutch pedal position switch connector C-01.
2.Measure the continuity between the terminals.
Q: Is the continuity meet the table above?
YES : Go to Step 2.
NO : Replace the clutch pedal position switch.
Refer to GROUP 23A, Transmission
Then check that the malfunction is eliminated.
