STEP 3. Check clutch pedal position switch connector
C-01, auto-cruise control-ECU connector C-20 and
intermediate connector C-89.
Q: Is any connector damaged?
YES : Repair or replace connector. Refer to GROUP 00E,
Harness Connector Inspection
. Then check
that the malfunction is eliminated.
NO : Go to Step 4.

STEP 4. Check the harness wire between clutch pedal
position switch connector C-01 (terminal number 2) and
auto-cruise control-ECU connector C-20 (terminal number
13).
Q: Is any harness wire between clutch pedal position
switch connector C-01 (terminal number 2) and
auto-cruise control-ECU connector C-20 (terminal
number 13) damaged?
YES : Repair the harness wire and then check that the
malfunction is eliminated.
NO : Go to Step 5.
STEP 5. Check the harness wire between clutch pedal
position switch connector C-01 (terminal number 1) and
ground wire.
Q: Is any harness wire between clutch pedal position
switch connector C-01 (terminal number 1) and ground
wire damaged?
YES : Repair the harness wire and then check that the
malfunction is eliminated.
NO : Check that the malfunction is eliminated. If the
malfunction is not eliminated, replace the auto-cruise
control-ECU (Refer to
.). Then check that the
malfunction is eliminated.

CIRCUIT OPERATION
This circuit transmits the "N" or "P" position signal of
the transmission range switch to the auto-cruise con-
trol-ECU. When the transmission range switch is at
the "N" or "P" position, auto-cruise control-ECU ter-
minal number 13 will receives 0 volt.
.
TECHNICAL DESCRIPTION (COMMENT)
The cause is probably an open-circuit in the output
signal circuit in "N" range.
.
TROUBLESHOOTING HINTS
• Malfunction of the transmission range switch.
• Damaged harness or connector.
• Malfunction of the auto-cruise control-ECU.
DIAGNOSIS
Required Special Tool:
• MB991223: Harness Set
STEP 1. Check the output circuit voltage at transmission
range switch connector B-41 (terminal number 10) by
backprobing.
(1) Do not disconnect transmission range switch connector
B-41.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 10 and ground by
backprobing.
• Voltage should be battery positive voltage. (When select
lever is in a position other than "N" range.)
• Voltage should be 0.5 volt or less. (When select lever is
in "N" range.)
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the voltage within specifications?
YES : Check that the malfunction is eliminated. If the
malfunction is not eliminated, replace the auto-cruise
control-ECU (Refer to
.). Then check that the
malfunction is eliminated.
NO : Go to Step 2.
