STEP 9. Using scan tool MB991958, check the data list
item 74: Brake light switch, item 89: Normally closed brake
switch.
(1) Connect scan tool MB991958 to the data link connector

(Refer to

P.17-12

).

(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991958 to data reading mode for cruise

control system (Refer to

• When the brake pedal is depressed, the display on

scan tool MB991958 should be "ON".

• When the brake pedal is released, the display on

scan tool MB991958 should be "OFF".

Q: Is the switch operating properly?

YES : Go to Step 10.
NO : Repair the stoplight switch system (Refer to

P.17-29

,

Diagnostic Trouble Code Procedures

− DTC 22:

Stoplight Switch System.) Then go to Step 12 .

STEP 10. Using scan tool MB991958, check the data list
item 88: Neutral switch.
(1) Connect scan tool MB991958 to the data link connector

(Refer to

P.17-12

).

(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991958 to data reading mode for cruise

control system (Refer to

P.17-12

).

• Item 88: Neutral switch.

• When the selector lever is moved to "N" or "P" posi-

tion, the display on scan tool MB991958 should be
"ON".

• When the selector lever is moved to other than "N"

or "P" position, the display on scan tool MB991958
should be "OFF".

Q: Is the switch operating properly?

STEP 11. Check the symptom.
Q: Can cruise control be set?

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.00-15

).

NO : Replace the ECM [Refer to GROUP 13A, Engine

Control Module (ECM)

P.13A-887

] <2.4L Engine> or

[Refer to GROUP 13B, Engine Control Module (ECM)

P.13B-904

] <3.0L Engine>. Then go to Step 12.

STEP 12. Check the symptom.
Q: Can auto-cruise control be set?

YES : The procedure is complete.
NO : Return to Step 1.

Inspection Procedure 5: Hunting (Repeated Acceleration and Deceleration) Occurs at the Set Vehicle
Speed.

.

COMMENT

• The secondary pulley speed sensor signal (vehi-

cle speed signal) <2.4L Engine>, output shaft
speed sensor signal (vehicle speed signal) <3.0L
Engine>, or the throttle body is suspected.

• The secondary pulley speed sensor signal (vehi-

cle speed signal) <2.4L Engine> or output shaft
speed sensor signal (vehicle speed signal) <3.0L
Engine> is transmitted from the TCM to the ECM
via the CAN bus line.

NOTE: When the vehicle is driven with the
low-speed gear in the sport mode, hunting occurs
easily, however, this is not a failure.

.

TROUBLESHOOTING HINTS (THE MOST
LIKELY CAUSES FOR THIS CASE:)

• Malfunction of the CAN bus line system.

• Malfunction of the secondary pulley speed sensor

<2.4L Engine>.

• Malfunction of the output shaft speed sensor

<3.0L Engine>.

• Malfunction of the CVT system <2.4L Engine>.

• Malfunction of the A/T system <3.0L Engine>.

• Malfunction of the throttle body.

• Malfunction of the ECM.

DIAGNOSTIC PROCEDURE

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

CAUTION

If there is any problem in the CAN bus lines, an incorrect
diagnostic trouble code (DTC) may be set. Prior to this
diagnosis, diagnose the CAN bus lines (Refer to GROUP
54C, Trouble code diagnosis

P.54C-11
