STEP 14. 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 and the

auto-cruise control main switch to the "ON" position.

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

connector C-35 terminal 5 and ground by backprobing.

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

voltage?
YES : Go to Step 15 .
NO : Go to Step 17 .

STEP 15. Check intermediate connector C-41 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is any connector damaged?

YES : Repair or replace the damaged components. (Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

). Then go to Step 19 .

NO : Go to Step 16 .

STEP 16. Check the harness wire between auto-cruise
control-ECU connector C-35 (terminal No.5) and stoplight
switch connector C-66 (terminal No. 4).
Q: Is any harness wire between auto-cruise control-ECU

connector C-35 (terminal No.5) and stoplight switch
connector C-66 (terminal No. 4) damaged?
YES : Repair or replace the harness wire. Then go to Step

18 .

NO : Go to Step17 .

STEP 17. Check auto-cruise control-ECU connector C-35
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is the connector damaged?

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

GROUP 00E, Harness Connector Inspection

P.00E-2

). Then go to Step 19 .

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 18. Check the diagnostic trouble codes.
Q: Is DTC 14 set?

YES : Replace the auto-cruise control-ECU (Refer to

P.17-99

). Then go to Step 19 .

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

(Refer to GROUP 00, How to Use
