STEP 10. Check the harness wire between intermediate 
connector C-89 (terminal number 14) and auto-cruise 
control-ECU connector C-20 (terminal number 4).
Q: Is any harness wire between intermediate connector 

C-89 (terminal number 14) and auto-cruise control-ECU 
connector C-20 (terminal number 4) 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 not eliminated, replace the auto-cruise 
control-ECU (Refer to 

P.17-92

.). 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 21A, Clutch 

P.21A-10

. Then check that the 

malfunction is eliminated.

STEP 2. Check the output circuit voltage at auto-cruise 
control-ECU connector C-20 (terminal number 13) by 
backprobing.
(1) Do not disconnect auto-cruise control switch connector 

C-20.

(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 13 and ground by 

backprobing.

• Voltage should be 0.5 volt or less. (When clutch pedal is 

depressed.)

• Voltage should be battery positive voltage. (When clutch 

pedal is not depressed.)

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the voltage within specifications?

YES : Check that the malfunction is eliminated. If the 

malfunction is not eliminated, replace the auto-cruise 
control-ECU (Refer to 

P.17-92

.). Then check that the 

malfunction is eliminated.

NO :  Go to Step 3.
