SERVICE INFORMATION
When key registration is unsuccessful after BCM replacement, P161D (Immobilizer) may
set when the ignition is turned on.

 Defective Dongle (All Applied Vehicles with Dongle except Kicks)
 Defective Intelligent Key control unit (Kicks only)
 Defective BCM (All Applied Vehicles except Kicks)
NOTE: Dongles are installed ONLY on Canadian market vehicles.
Trouble Diagnosis
NOTE: If DTC B2196-52 is stored with P161D, perform the diagnosis procedure for DTC
B2196-52 first.

Before replacing the BCM, confirm that the keys were programmed correctly by
ensuring the vehicle will start and that the lock/unlock buttons function normally.
 If any keys do not function normally, re-register all of the keys.

After re-registering all of the keys, reconfirm each key’s function.
 If OK, erase the DTC to complete the repair.
 If NG, diagnose the Intelligent Key, Intelligent Key control unit, Dongle, BCM
and/or EPS control unit per the Electronic Service Manual (ESM).
