ID CODE REGISTRATION NECESSITY JUDGMENT TABLE

CAUTION: Do not replace the engine control module and KOS-ECU at the same time. When replacing several ECUs, always replace one ECU at a time, register the necessary IDs in it, and then replace the next ECU.

The individual unique ID code is stored in the transponder (small transmitter) and KOS-ECU, engine control module (ECM), keyless operation key, and steering lock unit for KOS. Under the conditions shown in the table, the corresponding ID code has to be registered with KOS-ECU or the ECM again.

NOTE: The KOS-ECU memory can memories the maximum 4 different keyless operation keys (keyless operation key ID codes and key IDs).
