CIRCUIT OPERATION
• For the stoplight switch, two switches, a stoplight
switch for the stoplight illumination and a brake
switch exclusively for the cruise control system,
are incorporated to improve the reliability.
• As for the stoplight switch, when the brake pedal
is depressed/released, the stoplight switch
ON/OFF signal is transmitted from the
ETACS-ECU to the ECM via CAN bus line.
• As for the brake switch, the ECM connector B-11
terminal number 108 monitor the state of the
brake switch. The brake switch turn ON/OFF
when the brake pedal is depressed/released, and
the input signal to the ECM connector B-11 termi-
nal number 108 changes. According to this
change, the ECM judges the state of the brake
switch.
.
DTC SET CONDITIONS
Check Condition
• The "CRUISE" indicator light illuminates.
Judgment Criteria
• Open/short in stoplight switch circuit.
• Open circuit in the brake switch circuit (between
ECM connector B-11 terminal number 108 and
body ground.)
• Malfunction of CAN bus line.
.
TROUBLESHOOTING HINTS (THE MOST
LIKELY CAUSES FOR THIS CASE:)
• Malfunction of CAN bus system.
• Damaged harness or connector.
• Malfunction of the fuse No.2 at the ETACS-ECU.
• Malfunction of the stoplight switch.
• Malfunction of the stoplight relay.
• 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
• MB991223: Harness Set
• MB992006: Extra Fine Probe
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
.)

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
).
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991958 to diagnose the CAN bus line
(Refer to
).
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
Then go to Step 12.
STEP 2. Using scan tool MB991958, check the data list
item 74: Brake light switch.
(1) Connect scan tool MB991958 to the data link connector
(Refer to
).
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991958 to data reading mode for cruise
control system (Refer to
).
• Item 74: Brake light switch.
• 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 6.
NO : Go to Step 3.

STEP 3. Check the stoplight operation.
Check the stoplight operation.
OK:
Brake pedal depressed: Stoplight will illuminate
Brake pedal not depressed: Stoplight does not illu-
minate
Q: Is the stoplight operating properly?
YES : Go to Step 4.
NO : Check the stoplight system (Refer to GROUP 54A,
Rear Combination Lamp, Symptom Procedures
−
Inspection Procedure 3
). Then go to Step
12 .
STEP 4. Using scan tool MB991958, check the ETACS
system data list item 290: Brake light switch.
(1) Connect scan tool MB991958 to the data link connector
(Refer to
).
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991958 to data reading mode for ETACS
system (Refer to GROUP 54A, Data List Reference Table
• Item 290: Brake light switch.
• 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 5.
NO : Replace the ETACS-ECU (Refer to GROUP 54A,
ETACS-ECU
STEP 5. Using scan tool MB991958, check the data list
item 74: Brake light switch.
(1) Connect scan tool MB991958 to the data link connector
(Refer to
).
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991958 to data reading mode for cruise
control system (Refer to
).
• Item 74: Brake light switch.
• 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 6.
YES : Replace the ECM [Refer to GROUP 13A, Engine
Control Module (ECM)
] <2.4L Engine> or
[Refer to GROUP 13B, Engine Control Module (ECM)
