CIRCUIT OPERATION
This circuit transmits the "N" or "P" position signal of 
the park/neutral position switch to the auto-cruise 
control-ECU. 
When the park/neutral position switch is at the "N" or 
"P" position, auto-cruise control-ECU terminal num-
ber 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 park/neutral position switch

• Damaged harness or connector

• Malfunction of the auto-cruise control-ECU

DIAGNOSIS

Required Special Tool:

• MB991223: Harness set

STEP 1. Measure the signal 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 13 and ground by backprobing.

• The measured voltage should measure battery positive 

voltage. (When select lever is in a position other than 
"N" range).

• The measured voltage should measure 0.5 volts or less. 

(When select lever is in "N" range).

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Are all of the measured voltage satisfied?

YES : Go to Step 5 .
NO :  Go to Step 2 .

STEP 2. Check park/neutral position switch connector 
B-01, intermediate connector C-30 and auto-cruise 
control-ECU connector C-35 for loose, corroded or 
damaged terminals, or terminals pushed back in the 
connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 3 .
NO :  Repair or replace the faulty connector. (Refer to 

GROUP 00E, Harness Connector Inspection 

P.00E-2

). Then go to Step 6 .
