.
CIRCUIT OPERATION
Power of the auto-cruise control-ECU is transmitted
from the ignition switch (IG1) to the auto-cruise con-
trol-ECU through fuse 8 in the junction block.
.
TECHNICAL DESCRIPTION (COMMENT)
The cause is probably a malfunction of the
auto-cruise control-ECU power supply circuit or the
auto-cruise control-ECU ground circuit.
.
TROUBLESHOOTING HINTS
• Damaged harness or connector
• Malfunction of the auto-cruise control-ECU

DIAGNOSIS
Required Special Tool:
• MB991223: Harness set
STEP 1. 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 6 and ground by backprobing.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?
YES : Go to Step 5 .
NO : Go to Step 2 .
STEP 2. 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 damaged components. (Refer
to GROUP 00E, Harness Connector Inspection
NO : Go to Step 3 .

STEP 3. Check junction block connector D-08 and D-06 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
NO : Go to Step 4 .
STEP 4. Check the harness wire between ignition switch
and auto-cruise control-ECU connector C-35 (terminal
No.6) for damage.
Q: Is any harness wire between ignition switch and
auto-cruise control-ECU connector C-35 (terminal No.6)
damaged?
YES : Repair or replace the harness wire. Then go to Step
12 .
NO : Go to Step 11 .

STEP 5. Measure the ground 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 14 and ground by backprobing.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage 0.5 volts or less?
YES : Go to Step 8 .
NO : Go to Step 6 .
STEP 6. 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 damaged components. (Refer
to GROUP 00E, Harness Connector Inspection
NO : Go to Step 7 .
