AUTO-CRUISE CONTROL
GENERAL DESCRIPTIONM1172000100281
By using the auto-cruise control system, the driver
can select and maintain a desired cruising speed
[between 40 km/h (25 mph) and 200 km/h (124
mph)] without depressing the accelerator pedal.NOTE: If engine speed reaches and exceeds 6000
r/min the Auto Cruise Control System will be can-
celled automatically.

AUTO-CRUISE CONTROL SYSTEM DIAGNOSIS
INTRODUCTION TO AUTO-CRUISE CONTROL SYSTEM DIAGNOSISM1172003300251
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
Engine ECU, control switches and sensors. The con-
trol switches and sensors monitor the state of the
vehicle. The Engine ECU controls the throttle valve
opening angle in the throttle body in accordance with
the input signals from the switches and sensors. If
the Engine ECU detects a problem on any of those

components, the Engine ECU estimates where the
problem may be occurring, and will set a diagnostic
trouble code. Diagnostic trouble codes cover the
auto-cruise control switch, stoplamp switch and
Engine ECU.
DIAGNOSTIC TROUBLESHOOTING STRATEGYM1172002000484
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. (Refer to P.17-11, Diagnostic
Function
How to Read and Erase Diagnostic
Trouble Codes).
4. If you can verify the condition but no auto-cruise
control system DTCs are set, the malfunction may
be intermittent. (Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
How
to Cope with Intermittent Malfunctions P.00-14).5. If you can verify the condition but there are no
auto-cruise control system DTCs, or the system
cannot communicate with Diagnostic Tool
MB991958 (MUT-III sub assembly), and find the
fault. (Refer to P.17-53, Symptom Chart).
6. If there is an auto-cruise control system DTC,
record the number of the code, then erase the
code from Engine ECU memory using the
Diagnostic Tool MB991958 (MUT-III sub
assembly). (Refer to P.17-11, Diagnostic Function
How to Read and Erase Diagnostic Trouble
Codes).
7. Re-create the auto-cruise control system DTC set
conditions to see if the same Auto-cruise Control
System DTC will set again. (Refer to P.17-11,
Diagnostic Function
How to Read and Erase
Diagnostic Trouble Codes).
If the same Auto-cruise Control System DTC sets
again, perform the diagnostic procedures for the
set code. (Refer to P.17-14, Diagnostic Trouble
Code Chart).
