Without Scan Tool

Registration of additional keys without using the scan tool
Operate two registered ignition keys by the following procedure, call additional registration mode for the immobilizer ECU, then register an additional ignition key by operating it. Additional ignition keys can be registered without using the MUT-II by operating two ignition keys that already have been registered to the vehicle and operating an additional key to be registered. (A maximum of eight ignition keys can be registered.)

1. The ignition switch is "ON"by using he first key (KEY A) which has already been registered to the vehicle.
2. If the first key (KEY A) is correct, the immobilizer-ECU begins the condition on warning the second key (KEY B) which has already been registered to the vehicle. The ignition switch has been on the "ON"position for longer than 5 seconds so that enters the condition of waiting the second key (KEY B).
3. After the ignition switch is "LOCK" (OFF), it is "ON"by the second key (KEY B) which has already been registered to the vehicle. The second key (KEY B) must be turned on within 7 seconds of removing the first key.
4. If the second key (KEY B) is correct, the immobilizer-ECU enters the addition entry mode. And the theft alarm indicator light blinks approx. twice a second.




5. After the theft alarm indicator light blinks, the ignition switch is "LOCK" (OFF). And it is "ON"by using the new transponder key. The time which the key can be registered is limited than 30 seconds after the indicator blinks.
6. The time which the key can be registered is limited less than 30 seconds after the theft alarm indicator blinks.
7. The immobilizer-ECU controls as follows by the new key condition.




8. To continue to register another key, set the ignition switch to "LOCK" (OFF) position, and turn the ignition key to be registered "ON"within seven seconds. (the maximum of 8 keys can be registered to each vehicle. If the 9th key registers, the registration will be refused.)
9. The additional registration mode is terminated when any of the following conditions is met:
- The ignition key is "ON"position keeps more than 30 seconds. (the time-out of addition entry mode)
- The engine control relay is off after key is turned to "LOCK" (OFF) position.
- Start the communication with scan tool

10. The addition registered key can start engine, after the key turned off and the engine control relay is off.
