PURPOSE
Some vehicles may display the ACC, FCM, and/or ASC warnings and DTCs may be recorded in the ASC
− ECU. The warnings occur under the following conditions:
(1) When starting to climb a grade immediately after
descending a steep hill with the Adaptive Cruise
Control (ACC) engaged, the following messages
may be displayed on the MID.
D
FCM SERVICE REQUIRED
D
ACC SERVICE REQUIRED
D
ASC SYSTEM SERVICE REQUIRED (with
DTCs C1800, C1777)
The ECU determines this is abnormal acceleration
and the system may enter “fail−safe” mode with ACC
and FCM becoming inoperative.
(2) When driving in a lane with normal traffic flow, and an
adjacent lane is jammed, FCM SERVICE
REQUIRED, ACC SERVICE REQUIRED and ASC
SYSTEM SERVICE REQUIRED may be displayed
(with DTCs C1802, C1777).
The continued presence of objects creates
continuous inputs to trigger FCM operation. The
system determines this as an abnormal signal. The
system may enter “fail−safe” with ACC and FCM
becoming inoperative.
(3) ASC SYSTEM SERVICE REQUIRED may be
displayed without DTCs.
This TSB instructs dealers to reprogram the ASC−ECU
with new software to resolve mis−detections.

6. STANDALONE MUT−III SCAN TOOL VIEWER (STV)
ONLY:
(MEDIC 3 USERS GO TO THE
REPROGRAMMING PROCEDURE ON PAGE 4).
Verify your MUT−III has the most current version of the
reprogramming database:
N13101

D
Select “Special Function”
D
Select “ECU Reprogramming”
D
Select “Database File Display−CAN”

Confirm the database number displayed at the
top right of the chart is N13101 or higher
(1) If the database number displayed on your
MUT−III is N13101 or higher, continue to the
Reprogramming Procedure on page 4.
(2) If the database number displayed on your
MUT−III is lower than N13101, locate the
N13101 Reprogramming CD and follow the
instructions on the CD label to update your
MUT−III.
REPROGRAMMING PROCEDURE
CONNECT A BATTERY CHARGER TO THE VEHICLE’S BATTERY DURING THE
REPROGRAMMING PROCEDURE. DO NOT ALLOW THE BATTERY CHARGER TO TIME OUT.
BATTERY VOLTAGE (AS MEASURED AT THE BATTERY POSTS WITHOUT ELECTRICAL LOAD)
MUST BE KEPT AT 12.4V OR HIGHER IN ORDER TO REPROGRAM THE ASC−ECU. MEASURE
THE BATTERY VOLTAGE AND CHARGE AS NECESSARY.
NOTE:
VCI Stand−alone reprogramming is not available for this procedure. The laptop and
the VCI must remain connected for the entire procedure.
Connect the equipment as follows:
USB CABLE
VCI − LAPTOP
MEDIC−II / MUT−III
MAIN HARNESS
BLUE END
VCI
MEDIC 3 / MUT−III LAPTOP
D
Turn the laptop computer on. If you’re running on battery power and the charge indicator in the lower
right hand corner of the screen does not show a full charge, it is recommended that either the laptop
battery be charged prior to beginning, or that reprogramming be completed with the A/C power adaptor connected to the laptop.
D
Connect the USB cable to the VCI.
Page 5 of 11
