Key ID Register

NOTE: Using the key ID register function will cause all key IDs that have been previously registered in the immobilizer-ECU to be erased. All keys need to be registered. Those which have been registered before should be on hand before using this function.

NOTE: If registering more than one key, do not disconnect scan tool MB991502 halfway through the registration process. If the ignition switch is turned to "ON" position while scan tool MB991502 is disconnected, restart the registration operation from the first key.

NOTE: After registering key IDs, check that the engine can be started using all of the keys that have been registered. If the engine will not start, refer to IMMOBILIZER SYSTEM DIAGNOSIS .

Connect the scan tool to the data link connector. Select Immobilizer, then select "SPECIAL FUNCTION." Select "key ID register."
Input the password. Use the "UP" and "DOWN" keys to change the current password digit to a value between 0 and 9. Use the "LEFT" and "RIGHT" keys to move to a different password digit. Press the "YES" key to accept the password.
