ID CODE REGISTRATION NECESSITY JUDGMENT TABLE


caution Do not replace the engine-ECU 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 integrated in the emergency key, engine-ECU, 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 engine-ECU again.
note The KOS-ECU memory can memorise the maximum 4 different keyless operation keys (keyless operation key ID codes) and maximum 8 different emergency keys (key IDs).
