AUTO-CRUISE CONTROL
TSB Revision
ENGINE AND EMISSION CONTROL
17-23
STEP 7. Check auto-cruise control vacuum pump
connector A-01 and intermediate connector C-06.
Q: Is any connector damaged?
YES : Repair or replace connector.
Refer to GROUP 00E, Harness Connector Inspection
.
Then check that diagnostic trouble code 14 is not
output.
NO : Check the harness wire between stoplight switch
connector C-03 and auto-cruise control vacuum pump
connector A-01 for open circuit or damage.
Then repair if necessary.
Then check that diagnostic trouble code 14 is not
output.
STEP 8. Check the output circuit voltage at auto-cruise
control-ECU connector C-20 by backprobing.
(1) Do not disconnect auto-cruise control-ECU connector C-20.
(2) Turn the ignition switch to "ON" position and the auto-cruise
control main switch to "ON" position.
(3) Measure the voltage between terminal 7 and ground by
backprobing.
•
Voltage should be battery positive voltage.
[When decelerating with the "SET" switch while driving
at constant speed (Release valve open).]
(4) Measure the voltage between terminal 8 and ground by
backprobing.
•
Voltage should be battery positive voltage.
[When decelerating with the "SET" switch while driving
at constant speed. (Control valve open).]
(5) Measure the voltage between terminal 16 and ground by
backprobing.
•
Voltage should be battery positive voltage.
(When the motor is stopped during a constant road
speed.)
(6) Turn the ignition switch to "LOCK" (OFF) position.
Q: Are all of the above values satisfied?
YES : Check that diagnostic trouble code 14 is not output.
If diagnostic trouble code 14 is output, replace the
auto-cruise control-ECU. (Refer to
.)
Then check that diagnostic trouble code 14 is not.
NO : Go to Step 9.
