CRUISE CONTROL

TSB Revision

ENGINE AND EMISSION CONTROL

17-45

Inspection Procedure 3: When the "CANCEL" Switch is Set to ON, Cruise Control System is not
Cancelled.

.

COMMENT

The cause is probably an open-circuit in the output
circuit inside the "CANCEL" switch.

.

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

• Malfunction of the cruise control switch.

• 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

STEP 1. Using scan tool MB991958, check the data list
item 75: Cancel switch.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(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 75: Cancel switch.

• When the "CANCEL" switch is pressed, the display

on scan tool MB991958 should be "ON".

• When the "CANCEL" switch is released, the display

on scan tool MB991958 should be "OFF".

Q: Is the switch operating properly?

YES : Go to Step 2.
NO : Repair the cruise control switch system (Refer to

P.17-16

, Diagnosis Code Procedures

− DTC 15:

Cruise Control Switch System.) Then go to Step 3 .

STEP 2. Check the symptom.
Q: When the "CANCEL" switch is pressed, is the cruise

control cancelled?
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 Malfunctions

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 3.

STEP 3. Check the symptom.
Q: When the "CANCEL" switch is pressed, is the cruise

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

Inspection Procedure 4: Cruise Control cannot be Set (No Response "COAST/SET" Switch and
"ACC/RES" Switch is Pressed).

.

COMMENT

The fail-safe function is probably canceling cruise
control system. In this case, checking the cruise con-
trol system, MFI system, CVT system <2.4L Engine>
or A/T system <3.0L Engine>, ASC system <vehicles
with ASC> and CAN bus line system for DTCs. The
scan tool MB991958 can also be used to check if the
circuits of each input switch are normal or not by
checking the data list.
NOTE: Press the cruise control switches one by one
securely. Otherwise, the cruise control system may
not be started.

.

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

• Malfunction of the CAN bus line system.

• Malfunction of the MFI system.

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

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

• Malfunction of the ASC system <vehicles with

ASC>.

• Malfunction of the cruise control switch.

• Malfunction of the stoplight switch.

• Malfunction of the transmission range switch.

• Malfunction of the TCM.

• 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
DTC may be set. Prior to this diagnosis, diagnose the CAN
bus lines (Refer to GROUP 54C, Trouble code diagnosis

P.54C-11

.)

ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(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 diagnose the CAN bus line

(Refer to

P.17-12

).

Q: Is the check result satisfactory?

YES : Go to Step 2.
NO : Repair the CAN bus lines (Refer to GROUP 54C,

Diagnosis
