AUTO-CRUISE CONTROL SYSTEM DIAGNOSIS

INTRODUCTION TO AUTO-CRUISE CONTROL SYSTEM DIAGNOSIS

M1172003300284

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 
powertrain control module (PCM), control switches 
and sensors. The control switches and sensors mon-
itor the state of the vehicle. The PCM controls the 
throttle valve opening angle in the throttle body in 

accordance with the input signals from the switches 
and sensors. If the PCM detects a problem on any of 
those components, the PCM estimates where the 
problem may be occurring, and will output a diagnos-
tic trouble code. Diagnostic trouble codes cover the 
auto-cruise control switch, stoplight switch and PCM.

AUTO-CRUISE CONTROL SYSTEM DIAGNOSTIC TROUBLESHOOTING STRATEGY

M1172002000309

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 GROUP 00, How to 
Use Troubleshooting/Inspection Service Points 

−

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

auto-cruise control system DTCs, or the system 
cannot communicate with scan tool MB991502, 
refer to Symptom Chart 

P.17-39

 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.17-15

, Auto-cruise Control 

System Diagnostic Trouble Code Chart.
