Immobilizer System
Status Log
If you suspect there is a immobilizer system problem, check the status log in the HDS.
1. Connect the HDS to the data link connector.
2. Turn the ignition switch to ON (II).
3. On the HDS screen, at MAIN MENU, enter IMMOBILIZER, then select IMMOBILIZER SET-UP, select IMMOBILIZER INFORMATION, then
select STATUS LOG.
4. Check the STATUS LOG count. Troubleshoot the status with the highest count first. If no counts are listed, the immobilizer system is OK.
Continue with normal symptom troubleshooting.

Immobilizer Key Registration
NOTE:
• The HDS is required for registration of the
immobilizer keys.
• Programming the immobilizer also programs the
keyless transmitter.
• Check for aftermarket electrical equipment that can
cause problems with transponder operation.
• The immobilizer-keyless control unit can store up to
six immobilizer keys.
1. Have a registered key, a new immobilizer key, and
the first password from the iN system.
2. Connect the HDS to the data link connector.
3. Turn the ignition switch to ON (II).
4. Select IMMOBILIZER from the SYSTEM SELECT
menu.
5. Select Add and Delete keys, then Add 1 key.
6. Do the registration according to the instructions on
the HDS screen.
7. Check if the engine can be started with the newly
registered key.
8. When prompted by the HDS, do the keyless
transmitter programming.
1. Have all registered keys, all new keys, and the first
password from the iN system.
2. Connect the HDS to the data link connector.

NOTE: Before testing the immobilizer system, troubleshoot the system using B-CAN System Diagnosis Test Mode A
(see page 22-93) and check the No. 10 (7.5 A) and No. 38 (30 A) fuses in the under-dash fuse/relay box.
1. Remove the driver’s dashboard lower cover (see page 20-102).
2. Remove the steering column covers (see page 17-9).
3. Disconnect the 7P connector (A) from the immobilizer-keyless control unit (B).
4. Inspect the connector and socket terminals to be sure they are all making good contact.
• If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
• If the terminals look OK, go to step 5.
