AUTO-CRUISE CONTROL

GENERAL DESCRIPTION

M1172000100258

By using the auto-cruise control, the driver can drive 
at the desired speed [in a range of approximately 40 
− 200 km/h (25 − 124 mph)] without depressing the 

accelerator pedal.

AUTO-CRUISE CONTROL SYSTEM DIAGNOSIS

INTRODUCTION TO AUTO-CRUISE CONTROL SYSTEM DIAGNOSIS

M1172003300239

The auto-cruise control system allows driving without 
stepping on the accelerator pedal by setting a ran-
dom speed between 40 km/h (25 mph) and 200 km/h 
(124 mph). Problems in this system can be investi-
gated by the following methods.

Auto-cruise control system diagnostic 
trouble codes

The auto-cruise control system consists of the 
auto-cruise control-ECU, control switches, sensors 
and vacuum pump. The control switches and sen-
sors monitor the state of the vehicle. Based on input 
signals from those switches and sensors, the 

auto-cruise control-ECU activates the vacuum pump. 
If the auto-cruise control-ECU detects a problem on 
any of those components, the ECU estimates where 
the problem may be occurring, and will output a diag-
nostic trouble code. Diagnostic trouble codes cover 
the throttle position sensor, auto-cruise control 
switch, vehicle speed sensor <M/T>, auto-cruise 
control-ECU and vacuum pump.

AUTO-CRUISE CONTROL SYSTEM DIAGNOSTIC TROUBLESHOOTING STRATEGY

M1172002000257

Use these steps to plan your diagnostic strategy. If 
you follow them carefully, you will check most of the 
possible causes of an auto-cruise control system 
problem.
1. Gather information from the customer.
2. Verify that the condition described by the 

customer exists.

3. Check the vehicle for any auto-cruise control 

system DTC.

4. If you can verify the condition but no auto-cruise 

control system DTCs are set, and the malfunction 
may be intermittent. Refer to GROUOP 00, How 
to Use Troubleshooting/Inspection Service Points 
− How to Cope with Intermittent Malfunctions 

P.00-6

.

5. If you can verify the condition but there are no 

auto-cruise control system DTCs, or the system 
cannot communicate with scan tool MB991958, 
refer to Symptom Chart 

P.17-48

 and find the fault.

6. If there is an auto-cruise control system DTC, 

record the number of the code, then erase the 
code from vehicle memory using the scan tool.

7. Re-create the auto-cruise control system DTC set 

conditions to see if the same Auto-cruise Control 
System DTC will set again.

• If the same Auto-cruise Control System DTC sets 

again, perform the diagnostic procedures for the 
set code. Refer to 

P.17-12

, Auto-cruise Control 

System Diagnostic Trouble Code Chart.
