STEP 2. Using Diagnostic Tool MB991958, read the MPI
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 MPI system diagnostic trouble code(Refer to
GROUP 13A, MPI Diagnosis
Diagnostic Function How
to Read and Erase Diagnostic Trouble Code 13A-6).
(4) Turn the ignition switch to the "LOCK" (OFF) position.
(5) Disconnect Diagnostic Tool MB991958.
Q: Is DTC U1108 set?
YES : . Then go to Step 4.
NO : Go to Step 3.
STEP 3. Retest the system.
Q: Does the "CRUISE" indicator lamp illuminate when the
"CRUISE" (MAIN) switch is turned "ON"?
YES : It can be assumed that this malfunction is intermittent.
(Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
How to
Cope with Intermittent Malfunction P.00-14).
NO : Replace the Engine ECU. [Refer to GROUP 13A,
Engine ECU 13A-675]. Then go to Step 4.
STEP 4. Retest the system.
Q: Does the "CRUISE" indicator lamp illuminate when the
"CRUISE" (MAIN) switch is turned "ON"?
YES : The procedure is complete.
NO : Return to Step 1.

AUTO-CRUISE CONTROL SWITCH CHECKM1172001200054
AUTO-CRUISE CONTROL MAIN SWITCH CHECK
1. Turn the ignition switch to the "ON" position.
2. Check that the "CRUISE" indicator lamp within the
combination meter illuminates when the "CRUISE" (MAIN)
switch is switched "ON".
AUTO-CRUISE CONTROL SETTING
1. Switch "ON" the "CRUISE" (MAIN) switch.
2. Drive at the desired speed, above approximately 40 km/h.
3. Push the auto-cruise control switch in the direction of the
arrow.
4. Check to be sure that when the switch is released the speed
is the desired constant speed.
NOTE: If the vehicle speed decreases to approximately 15
km/h below the set speed because of climbing a hill for
example, it is normal for the auto-cruise control to be can-
celled.

THROTTLE POSITION SENSOR
Refer to GROUP 13A, On-vehicle Service Throttle Actuator
Control Motor Check 13A-671 (3.8L engine).
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 movement at any time. Do
not under any circumstance activate the throttle plate
by hand.
When removing the throttle body from the intake
manifold disconnect the wiring first.During replace-
ment connect the wiring last.
Do not activate the throttle body using a DC supply to
test the motor, as permanent damage to the throttle
body will result.
