Immobilizer System Reprogram Procedure

IMMOBILIZER SYSTEM REPROGRAM PROCEDURE [WITH KEYLESS ENTRY SYSTEM]

CAUTION:
- Do not perform key registration or start the engine under the following conditions. Doing so could result in a key registration error or the engine not starting even with a correctly programmed key.
- If a large, metal object is close to a valid key
- If an electrical device is close to a valid key
- If two or more valid keys are on the same key ring

NOTE:
- When an error occurs during the reprogram procedures, except when the PCM is 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), 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 PCM.
- The immobilizer system cannot be deactivated.
- Confirm that all keys programmed 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 programming two keys.
- If the engine is started during the key registration procedure, the key registration mode will be erased. Therefore, do not start the engine until the key registration procedure for all the necessary keys is finished.
- A maximum of 8 keys can be programmed for one vehicle.
- To start the engine, two or more keys need to be programmed.

Key Addition

1. Cut new transponder-equipped key(s).
2. Using key 1, turn ignition switch to ON position.
1. Observe illumination of security light in instrument cluster.
2. After the security light turns off (after approx. 3 seconds from when ignition switch is turned to the ON position), turn key 1 to the LOCK position within approx. 4 seconds and remove it from the steering lock.
3. Repeat Step 2 with key 2.
4. Repeat Step 2 with key 3.
5. If there are 4-8 keys (new keys), repeat Step 2.
6. Verify that the engine starts using the programmed key.

When the customer has only one or no valid key
- If only one or no valid key is available, use the SST (WDS or equivalent) to register additional keys. (Key registration using SST (WDS or equivalent))

Key registration using SST (WDS or equivalent)

NOTE:
- Additional keys can be programmed without having to erase the key codes already programmed.
- If 8 keys have already been programmed, this procedure cannot be used to register a key. To register a key under this condition, it is necessary to first erase all the key codes. (Key Replacement)

1. Cut new transponder equipped key(s) if necessary.
2. Connect the SST (WDS or equivalent).
3. Using key 1, turn ignition switch to the ON position.
- Valid key: The security light illuminates, then turns off after approx. 3 seconds.
- New key: The security light flashes rapidly for approx. 1 minute and start displaying the DTC 15 (WDS or equivalent: DTC B1601).
1. Perform security access approval. (Security Access Procedure.)
2. Select "Ignition Key Code Erase".

NOTE: Do not select any other command from this menu.

3. Turn key 1 to the LOCK position for more than 1 second.
4. Turn key 1 to the ON position for more than 3 seconds.

NOTE: Security light will remain illuminated as long as key is in the ON position.

5. Remove key 1 from the steering lock.

NOTE: After approx. 1 minute security light: DTC 21 (WDS or equivalent: DTC B1213) is output

4. Using key 2, turn ignition switch to the ON position for more than 3 seconds. Observe that security light illuminates (for approx. 3 seconds).
1. Verify that the security light is not illuminated, then turn key 2 to the LOCK position and remove from the steering lock.

5. If there are 3--8 keys (valid and/or new keys), repeat Step 4.
6. Verify that the engine starts using the programmed key.

PCM Replacement

- PCM must be replaced by performing "Programmable Module Installation Procedure".
- After PCM replacement, and programmable module installation has been performed, refer to the procedure for "Key Replacement", and perform key programming. (Key Replacement.)

NOTE: To start the engine, two or more keys need to be programmed.

Customer Spare Key Programming Without Using SST (WDS or equivalent) Set-up

NOTE: With this function, enabling and disabling of the "When the customer has two or more valid keys" function can be set using the SST (WDS or equivalent). This function is provided to prohibit drivers from performing the reprogram procedure on vehicles owned by rental car companies or other large vehicle fleet owners.

1. Connect the SST (WDS or equivalent).
2. Using valid or new key, turn ignition switch to the ON position.
3. Perform security access approval. (Security Access Procedure.)
4. Select "Customer Spare Key Programming Enable/Disable".
5. The chart indicates setting of the customer spare key programming.

NOTE: At the time of new vehicle delivery, the function is set on "Enable".

Security Access Procedure

NOTE: When using the SST (WDS or equivalent) to perform "Ignition Key Code Erase" or "Customer Spare Key Programming Enable/Disable", it is necessary to obtain security access approval.

1. Connect the SST (WDS or equivalent).
2. Select "Tool box", "Body", "Security", and then "PATS Functions" (in this order).
3. The SST (WDS or equivalent) will read out an outcode depending on the designated procedure.

CAUTION: After reading out the outcode, do not turn ignition switch from LOCK to ON position 5 times, otherwise the outcode value will be changed.

4. Access the Mazda official website to obtain the incode that corresponds to the outcode. Refer to Service Information Ref. No. A001102 for details of this procedure.
5. Input the incode to the SST (WDS or equivalent).
6. Verify that the security access procedure finishes normally.
