positive voltage is applied to the ECM (terminal 108),
and the signal is transmitted from the ETACS-ECU to
the ECM via CAN bus line.

Q:Is the check result satisfactory?
YES:
Go to Step 2
NO:
Repair the CAN bus lines (Refer to GROUP 54D,
Diagnosis - CAN Bus Diagnostics Chart P.54D-17). Then
go to Step 15.
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 P.17b-5).
(2)
Turn the ignition switch to the "ON" position.
(3)
Set scan tool MB991958 to data reading mode for auto-cruise
control system (Refer to P.17b-5).
⦆
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".
(4)
Turn the ignition switch to the "LOCK" (OFF) position.
(5)
Disconnect scan tool MB991958.
Q:Is the switch operating properly?
YES:
Go to Step 9.
NO:
Go to Step 3.
STEP 3. 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 P.17b-5).
(2)
Turn the ignition switch to the "ON" position.
(3)
Set scan tool MB991958 to data reading mode for ETACS
system (Refer to GROUP 54Ad, Diagnosis - Data List
Reference Table P.54Ad-51).
⦆
Item 290, Brake light switch.
⦆
When the brake pedal is depressed, the display on

AUTO-CRUISE CONTROL SYSTEM DIAGNOSIS
⦆
When the brake pedal is released, the display on scan
tool MB991958 should be "OFF".
(4)
Turn the ignition switch to the "LOCK" (OFF) position.
(5)
Disconnect scan tool MB991958.
Q:Is the switch operating properly?
YES:
Replace the ECM. When the ECM is replaced, register
the encrypted code (Refer to GROUP 42C, Diagnosis - ID
Code Registration Necessity Judgment Table P.42C-8).
Then go to Step 15.
NO:
Go to Step 4.
STEP 4. Check fuse number 2 at the ETACS-ECU.

Fuse number 2
(Housing color: Blue)
Q:Is the fuse in good condition?
YES:
Go to Step 5.
NO:
Check the stoplight system harness and replace the
fuse. Then go to Step 15.
STEP 5. Check the stoplight switch.
(1)
Remove the stoplight switch (Refer to GROUP 35A, Brake
Pedal P.35A-22).

Stop light switch
(2)
Connect an ohmmeter to the stoplight switch between
terminals 1 and 2.
(3)
Check for continuity between the terminals when the plunger
of the stoplight switch is pushed in and when it is released.
(4)
The stoplight switch is operating properly if the circuit is open
between terminals 1 and 2 when the plunger is pushed in to
a depth of within 4.0 mm (0.16 inch) from the outer case edge
surface, and if the resistance value is less than 2 ohms
between terminals 1 and 2 when it is released.
Q:Is the stoplight switch operating properly?
YES:
Install the stoplight switch (Refer to GROUP 35A,
Brake Pedal P.35A-22). Then go to Step 6.
NO:
Replace the stoplight switch (Refer to GROUP 35A,
Brake Pedal P.35A-22). Then go to Step 15.
STEP 6. Check stoplight switch connector C-124 and
ETACS-ECU connector C-304 and C-312 for loose, corroded
or damaged terminals, or terminals pushed back in the
connector.
Q:Are the connectors and terminals in good condition?
