Security System and Locks System: Other Mazda MX-5 NB рестайлинг

IMMOBILIZER SYSTEM SERVICE CAUTION

Scheme 76

1. Disconnect the negative battery cable.
2. Remove in the order indicated in the figure.
3. Install in the reverse order of removal. CAUTION: After replacing the immobilizer unit with a new one, the engine cannot be started without reprogramming the ID number of the keys and the code word of the new immobilizer unit. Input the ID number and code word. (See «IMMOBILIZER SYSTEM REPROGRAM PROCEDURE»(ref-194474-S37685660362005092800000) .)

IMMOBILIZER SYSTEM REPROGRAM PROCEDURE

Note. When an error occurs during the reprogram procedures, except when both the immobilizer unit and PCM are replaced, repeat the procedure from Step 1. If you still cannot reprogram, confirm how many keys can start the engine. Then, perform the key replacement or addition reprogram procedure according to the valid key number. To make a copy of the key or replace the immobilizer system component parts (the key(s), steering lock, immobilizer unit and/or PCM), the customer should bring all keys to the dealer. This is because the previously programmed key IDs are erased when reprogramming the key IDs into the immobilizer unit and PCM. If the customer has only one valid key when replacing the immobilizer system component parts, the dealer should contact a distributor to obtain the code word. To replace the immobilizer unit or PCM, there should be at least one valid key. Otherwise, both the immobilizer unit and PCM should be replaced. The immobilizer unit and PCM cannot be changed from one car to another. If an immobilizer unit or PCM is replaced with one from another car, the engine will not start. Reprogramming of the IDs and code word of an immobilizer unit that has already been programmed as set is not possible. The immobilizer unit and PCM should not be newly replaced as a trial during troubleshooting. If this is done, the ID and code word will be programmed into the new unit and it cannot be used for other cars even if you find that the old unit was normal. The immobilizer system cannot be deactivated. Confirm that all keys registered can start the engine after the reprogram procedure. When confirming, wait for more than 5 seconds before inserting the next key. When the customer does not need to register more than two keys, the following procedures can be stopped after registering two keys.

CODE WORD INPUT PROCEDURE

Note. A code word is composed of eight digits from 1-9 and is part of the immobilizer unit from the manufacturer. Each unit has its own code word. To obtain the code word, you need to have the immobilizer serial number, then ask the distributor. To input the code word into the PCM, turn the ignition key and count the number of flashes of the security light. The calculation of the number of flashes of the security light comes with the timing of the turning of the key.

Scheme 84

1. Wait for 5 minutes until security light flashes slowly. ( 300 ms ON- 300 ms OFF --> 1.2 s ON- 1.2 s OFF)
2. Input the code word as shown in the example. Turn ignition switch to ON position while security light is off and count three illumination cycles. As the light goes out after the third illumination, turn key to LOCK position. Wait at least one illumination cycle and within 30 seconds of going to LOCK position, turn ignition switch to ON position while security light is off and count one illumination cycle. As the light goes out after the first illumination, turn key to LOCK position. Repeat Step (2) for rest of six digits.
3. When code word is registered correctly in the PCM, the security light stops flashing and illuminates.
4. As soon as the security light stops flashing and illuminates, the following immobilizer system reprogram procedure should be started. NOTE: If the code word is not input correctly, the security light goes out after all eight digits are input. In this case, perform the "Code Word Input Error Recovery Procedure".

Examples of Incorrect Input of Code Word

Note. The security light must flash one or more times between the digits of the code word. If the code word is input incorrectly, the security light goes out. Turn the ignition switch to ON position then back to LOCK position five times (except PCM replacement) or six times (PCM replacement) and repeat the procedure to input all eight figures for the code word. When an error occurs during the reprogram procedures except when both the immobilizer unit and PCM are replaced, repeat the procedure from Step 1. If you still cannot reprogram, confirm how many keys can start the engine. Then, perform the key replacement or addition reprogram procedure according to the valid key number.

Scheme 88

1. The security light flashes ten or more times while the ignition switch is at ON position.
2. The ignition switch is turned to ON position and LOCK position while the security light is off.
3. The ignition switch is turned to LOCK position and ON position while the security light is on.
4. The ignition switch is turned to LOCK position and ON position while the security light is off.
5. The unmatching code word is input to the immobilizer unit.

Code Word Input Error Recovery Procedure

1. Turn ignition switch to ON position then back to LOCK position five times (except PCM replacement) or six times (PCM replacement). The key should not remain at ON position or LOCK position for more than 1 second.
2. Repeat the "CODE WORD INPUT PROCEDURE".
