This bulletin supercedes TSB-16-54-005, issued October, 2016, to add replacement and registration
of a new key set for cases where registration of the immobilizer ID still fails after performing the
Immobilizer Registration Procedure in TSB-16-54-005. Revisions are italicized and indicated by A.

PURPOSE
After replacing the ETACS ECU in vehicles without KOS, a “Key Error” message will be displayed on
MUT-III SE when re-registration of the immobilizer ID fails.
This TSB provides dealers a revised procedure to re-register the immobilizer ID after replacing the
ETACS ECU.
"

If re-registration of the immobilizer ID still fails after performing the registration instructions in “C.
IMMOBILIZER REGISTRATION PROCEDURE (VEHICLES WITHOUT KOS)” in this TSB, then the key set
must be replaced and re-registered using the Key Registration instructions (Barcode No. Method)
in the ID Codes Registration Instructions on MDL.

BACKGROUND
The failure of the ID re-registration may be caused by the Secret Key Code (SKC) value of the engine
ECU being rewritten unexpectedly by the ETACS ECU. This results in unmatching SKC values
between the engine ECU and ETACS ECU, which in turn causes failure of the ID re-registration of the
immobilizer.

AFFECTED VEHICLES
2014-2016 Outlander vehicles without KOS, built before July 2016.

REQUIRED OPERATIONS
EQUIPMENT
The following equipment is needed to re-register the immobilizer ID after replacing an
ETACS ECU.
D VCI (Vehicle Communication Interface) or VCI Lite - MB991824 or MB992744V.
