SYMPTOM PROCEDURES

Inspection Procedure 1: When the Brake Pedal is Depressed, Cruise Control System is not Cancelled.

.

COMMENT

• Malfunction of CAN bus line.

• The stoplight switch circuit is suspected.

.

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

• Malfunction of CAN bus system.

• Damaged harness or connector.

• Malfunction of the stoplight switch.

• Malfunction of the ETACS-ECU

• 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

.)

STEP 1. Using scan tool MB991958, diagnose the CAN bus 
line.

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 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 

− CAN Bus Diagnostics Chart

Q: Is the switch operating properly?

YES : Go to Step 3.
NO :  Repair the stoplight switch system (Refer to 

P.17-29

, 

Diagnostic Trouble Code Procedures 

− DTC 22: 

Stoplight Switch System.) Then go to Step 4 .

STEP 3. Check the symptom.
Q: When the brake pedal is depressed, 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
