STEP 6. Measure the signal voltage at auto-cruise 
control-ECU connector C-35 by backprobing.

(1) Do not disconnect connector C-35.
(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 3 and ground by 

backprobing.

• The voltage should measure battery positive voltage.

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

YES : Go to Step 7.
NO :  Go to Step 8.

STEP 7. Check auto-cruise control-ECU connector C-35 for 
looser, corroded or damaged terminals, or terminals 
pushed back in the connector

Q: Are the connector and terminals in good condition?

YES : Go to Step 10.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection

STEP 8. Check auto-cruise control-ECU connector C-35 
and intermediate connector C-41 for looser, corroded or 
damaged terminals, or terminals pushed back in the 
connector.

Q: Are the connectors and terminals in good condition?

YES : Go to Step 9.
NO :  Repair or replace the damaged components. Refer to
