STEP 8. Measure the output circuit voltage at auto-cruise 
control-ECU connector C-35 by backprobing.
(1) Do not disconnect auto-cruise control-ECU connector C-35.
(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between auto-cruise control-ECU 

connector C-35 terminal 4 and ground by backprobing.

• Voltage should measure battery positive volts. (When 

brake pedal is depressed).

• Voltage should measure 0.5 volts or less. (When brake 

pedal is not depressed).

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

YES : Go to Step 11 .
NO :  Go to Step 9 .

STEP 9. Check auto-cruise control-ECU connector C-35, 
stoplight switch connector C-66 and joint connector (2) 
C-10 for loose, corroded or damaged terminals, or 
terminals pushed back in the connector.
Q: Is the connector damaged?

YES : Repair or replace the damaged connector. (Refer to 

GROUP 00E, Harness Connector Inspection 

P.00E-2

). Then go to Step 12 .

NO :  Go to Step 10 .

STEP 10. Check the harness wire between stoplight switch 
connector C-66 (terminal No.3) and auto-cruise 
control-ECU connector C-35 (terminal No.4).
Q: Is any harness wire between stoplight switch connector 

C-66 (terminal No.3) and auto-cruise control-ECU 
connector C-35 (terminal No.4) damaged?
YES : Repair or replace the harness wire. Then go to Step 

12 .

NO :  It can be assumed that this malfunction is intermittent. 

(Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points 

− How to 

Cope with Intermittent Malfunction 

P.00-7

).

STEP 11. Check that the malfunction is eliminated.
Q: Is the malfunction eliminated?

YES : It can be assumed that this malfunction is intermittent. 

(Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points 

− How to 

Cope with Intermittent Malfunction 

P.00-7

).

NO :  Replace the auto-cruise control-ECU. (Refer to
