1. If it is noticed visually or audibly that the Dynamic
Response Pipes are fouling the Side Step Bracket
then please refer to TSB LTB00588
2. If the front end of the Deployable Side Step is
found to be loose when deployed, add 1 additional
shim to the inner mounting point on the front of the
bracket – See attached File – Side Step Extra Shim
Fitment. PDF
3. When conducting the initialisation procedure,
should the Deployable Side Steps not function
please see the attached file – Initialisation of
DSS.PDF
4. From Vin 120000 L405 and Vin 300000 L494,
should Deployable Side Steps & Tubes require
fitment then all the location bosses will require
tapping out. The SRO time allowance has now
been included in the fitment SRO.
5. Should a Dealer or Customer report a concern with
the Deployable Side Step System operation, then
at the first instance please use the DSS - ON
DEMAND SELF TEST procedure within SDD to
validate the system. Please see the attached file –
Self Test DSS.PDF

PREPRE-INITIALISATION OF DSS AFTER
INSTALLATION (SWITCHING THE SYSTEM
OFF/ON)

FUNCTION SWITCH INDICATOR DOES
NOT FLASH AFTER INITIALISATION
SEQUENCE

When the DSS is first installed the electronic
ECU module is delivered in an 'OFF' condition.
This is designed to prevent the steps from
deploying/stowing unintentionally after
installation.

It has been identified that the DSS
initialisation process does not always switch
the DSS system ON/OFF.

Before proceeding with initialisation of the
DSS module, the ignitiion should be switched
on and off to allow the vehicle network to be
awake; please refer to the owners hand book
for instructions.

After performing the "SWITCHING THE
SYSTEM ON/OFF" process, if the function
switch indicator does not flash the process
of "SWITCHING THE SYSTEM ON/OFF"
should be repeated up to 10 times until the
function switch indicator flashes.

If after 10 attempts the system still fails to
turn ON/OFF the system should be
INITIALISATION OF DSS
diagnosed with dealer network tools (SDD)
and any Device Trouble Codes (DTC's)
'SWITCHING THE SYSTEM OFF/ON '
shuold be cleared and the process from the
Initialisation of the DSS should be made within PRE-INITIALISATION stage repeated.
60 seconds of PRE-INITIALISATION.
The DSS system is switched ON as follows;
Ensure the ignition is OFF.
Press and hold the DSS function switch and
within 2* seconds of holding the DSS function
switch, press the START/STOP button to turn
the ignition on

The function switch indicator will flash 3 times
to indicate that the system is switched ON.
To switch the system OFF, the same
proceedure should be followed and the
function switch indicator will flash 2 times to
indicate that the system is off.
* Failure to turn the ignition ON within 2
seconds of pressing the function switch will
prevent the system from switching ON/OFF

DSS ONON-DEMAND SELF TEST MODE
With the DSS system fully connected in
vehicle, it is possile to validate the system to
determine if there are any component level
faults.
To access the self mode In SDD, under
Deployable Running Boards navigate to the
"Recommendations" tab where "General
Diagnostics and Tools" will be visible and
"Diagnostic - On demand self test - Running
board control module" can be selected.
This routine will deploy and stow the left and
right running board. During the deploy or
stowing it evaluates the relay, current
feedback, hall effect circuits and will drive the
status LED active. The sequence of execution
is: Stow Left (only if deployed upon entry into
self test), Deploy Left, Stow Left, Stow Right
(only if deployed upon entry into self test),
Deploy Right, Stow Right, then LED test
If the module detects a fault during the
excersise of this feature it will set or reset an
active DTC. If there is no active faults after the
test is complete, it should reply with a system
pass message
