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
