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 

P.00E-2

. 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 

P.17-92

.). 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 

P.17-92

.). Then check that the 

malfunction is eliminated.

NO :  Go to Step 2.
