CIRCUIT OPERATION
This circuit activates the vacuum pump used to 
accelerate/decelerate, set, and cancel the vehicle 
speed.
The auto-cruise control-ECU controls the control 
valve, release valve, and motor by turning the tran-
sistor in the ECU on and off.

.

DTC SET CONDITIONS
Any drive signal for the release valve, control valve 
or motor is not input to the auto-cruise control-ECU.

.

TROUBLESHOOTING HINTS
The most likely causes for this code to be set are:

• Malfunction of the auto-cruise vacuum pump.

• 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 and the 

auto-cruise control main switch to the "ON" position.

(3) Measure the voltage between auto-cruise control-ECU 

connector C-35 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 auto-cruise control-ECU 

connector C-35 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 auto-cruise control-ECU 

connector C-35 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 the "LOCK" (OFF) position.
Q: Are all of the above values satisfied?

YES : Go to Step 6 .
NO :  Go to Step 2 .
