AUTO-CRUISE CONTROL SYSTEM DIAGNOSIS INTRODUCTION TO AUTO-CRUISE CONTROL SYSTEM DIAGNOSIS The auto-cruise control system allows driving without stepping on the accelerator
pedal by setting a random speed between 40 km/h (25 mph) and 170 km/h (106
mph). Problems in this system can be investigated 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 monitor the state of
the vehicle. The PCM controls the throttle valve opening angle in the throttle body
in accordance with the in
put si
gnals 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 set a diagnostic trouble code. Diagnostic
trouble codes cover the auto-cruise control switch, stoplight switch and PCM. AUTO-CRUISE CONTROL SYSTEM DIAGNOSTIC TROUBLESHOOTING STRATEGY 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 HOW TO COPE WITH
INTERMITTENT MALFUNCTIONS
.
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 (MUT-III
sub assembly), refer to SYMPTOM CHART
, 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 DTC 15: AUTO
