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

DIAGNOSTIC TROUBLE CODE PROCEDURES
DTC P0830: Clutch Switch (5M/T Only)
.
CIRCUIT OPERATION
A 5 Volt power supply is applied to the clutch
switch output terminal (terminal No. 1) from the
ENGINE-ECU(terminal No. B-21 pin 41) when
the clutch pedal is applied the power supply is
switched to earth.
.
TECHNICAL DESCRIPTION
The ENGINE-ECU uses the clutch switch earth-
ing as a signal that clutch pedal has been
applied.
.
DTC SET CONDITIONS
Check Conditions
Vehicle speed is above 50 km/h.Judgement Criteria
Gear shift is above 5 times.
Clutch control is below 2 times.
No MIL.
No Limp home.
.
TROUBLESHOOTING HINTS (The most
likely causes for this code to be set are:)
Clutch switch failed
Harness damage in clutch switch circuit, or con-
nector damage.
Refer to component locations GROUP-70
Refer to configuration diagrams GROUP-80

DIAGNOSIS
Required Special Tools:
MB991958: Diagnostic Tool (MUT-III Sub Assembly)
MB991824: V.C.I.
MB991827: MUT-III USB Cable
MB991910: MUT-III Main Harness A
STEP 1. Using Diagnostic Tool MB991958, read the
diagnostic trouble code.
To prevent damage to Diagnostic Tool MB991958, always
turn the ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting Diagnostic Tool
MB991958.
(1) Connect Diagnostic Tool MB991958 to the data link
connector. (Refer to P.17-11).
(2) Turn the ignition switch to the "ON" position.
(3) Check for A/T system diagnostic trouble code. (Refer to
GROUP 23A, A/T Diagnosis
Diagnostic Function How
to Read and Erase Diagnostic Trouble Code P.23A-13).
(4) Turn the ignition switch to the "LOCK" (OFF) position.
(5) Disconnect Diagnostic Tool MB991958.
Q: Is any DTC set?
YES : Diagnose the A/T system. (Refer to GROUP 23A, A/T
Diagnosis
Diagnostic Trouble Code Chart
P.23A-34). Then go to Step 4.
NO : Go to Step 2.

AUTO-CRUISE CONTROL
ENGINE AND EMISSION CONTROL17-66
If the air intake duct is removed from the throttle body take great care to keep fingers away
from the throttle plate. The drive motor has very high torque and is capable of random move-
ment at any time. Do not under any circumstances activate the throttle plate by hand.
When removing the throttle body from the intake manifold disconnect the wiring first. During
replacement connect the wiring last.
Do not activate the throttle body using a DC suppy to test the motor,as permanent damage to
the throttle body will result.
