Registration Procedure for Remote Controller 
ID Code

S5JB0AA506009

NOTE

• It is possible to register up to 4 remote 

controllers in keyless start control module.

• Setting keyless start control module to ID 

code registration mode of remote 
controller will erase all remote controller ID 
codes that have been registered in keyless 
start control module.
Therefore, when registering remote 
controller ID codes in keyless start control 
module, have all of those to be registered 
ready and execute their registration at the 
same time.

• When registration of more than four 

remote controller ID codes is attempted, 
the oldest remote controller ID code will be 
erased and that inputted after the fourth 
one will be registered.

• When keyless start control module which 

was used in another vehicle has been 
installed, it is necessary to perform both 
registration of remote controller ID code in 
keyless start control module and 
registration of ignition key transponder 
code in ECM. For registration procedure of 
ignition key transponder code, refer to 
“Registration of the Ignition Key in Section 
10C”.
