Immobilizer System (Type 7)
(Supersedes 09-011, dated February 27, 2009, see REVISION SUMMARY)
REVISION SUMMARY
This service bulletin has been revised extensively. American Honda recommends that you review the entire bulletin.
BACKGROUND
The listed vehicles have a Type 7 GEN5 immobilizer system that disables the vehicle unless a programmed ignition key is used. The transponder in
the ignition key uses a rolling-type code instead of a set code.
In this service bulletin, a programmed ignition key refers to a transponder-type key or keyless transmitter that has been cut to fit the ignition switch
and whose transponder ID code is recognized by the immobilizer system. If you try to start the engine without a programmed ignition key, the engine
cranks, but won't start, or it starts, runs for one second, and stalls.
This service bulletin covers these subjects:
^ Immobilizer system components
^ Immobilizer transponder key description
^ System description
^ Adding and deleting keys
169
^ Starting the engine without a programmed ignition key
^ Troubleshooting the immobilizer system
^ Replacing the immobilizer-keyless control unit
^ Replacing the PCM
^ Replacing the driver's under-dash fuse/relay box
(MICU)
For more information on the immobilizer system, refer to the Body Electrical section of the appropriate service manual, or go online.
WARRANTY CLAIM INFORMATION
None. This service bulletin is for information only.
IMMOBILIZER SYSTEM COMPONENTS
NOTE:
When programming one or more of the immobilizer system components, the HDS may display:
"This function is locked." This requires you to get a release password from the iN (Interactive Network) to continue. To get the release password,
you need the attempt count recorded in the HDS.
The immobilizer system includes these components:
^ Immobilizer transponder keys
^ Immobilizer system indicator
^ Immobilizer-keyless control unit
^ PCM
^ Under-dash fuse/relay box (MICU) with built-in IMOES unit and 2-wire B-CAN communication
IMMOBILIZER TRANSPONDER KEY DESCRIPTION
Each vehicle comes with three immobilizer transponder keys (two master keys and one valet key).
Each master key and valet key has a transponder that outputs a rolling-type code (activated by the immobilizer-keyless control unit) when you insert
the key into the ignition switch and turn the switch to ON (II). The immobilizer system uses this code to determine whether to start the engine.
Both master and valet keys used with this system are sidewinder-type keys. You need a special key cutting machine such as the In-Code H.S. Key
Cutter to cut key blanks. You cannot use the Ilco Immobilizer Key Code Duplicator or Ilco programmable (T5) key blanks with this system.
For key cutting, use the appropriate tool from the Acura Tool and Equipment Program. Call or online: log in to the Interactive Network (iN), then
click on Service > Quick Links > Tool and Equipment Program.
NOTE:
The Type 7 immobilizer system differs from the Type 6 by its use of a two-wire B-CAN system.
170
The master keys have a battery-operated remote transmitter built into the grip for the keyless functions. The immobilizer function of the key does not
require a battery. The valet key does not contain a battery or other serviceable parts.
SYSTEM DESCRIPTION
Immobilizer Indicator
The immobilizer indicator is on the instrument panel.
When you insert a programmed ignition key (master or
valet) into the ignition switch and turn the switch to ON
(II), the indicator flashes once and then goes off.
At this point, the engine can be started by turning the ignition switch to START (Ill). Unlike previous systems, the indicator does not come on when
you turn the ignition switch to LOCK (0).
If you insert a nonprogrammed ignition key into the ignition switch and turn the switch to ON (II), the indicator flashes until the switch is turned to
LOCK (0). The immobilizer system results vary, depending on how quickly you turn the key.
^ If you turn the ignition switch quickly from LOCK (0) to START (III), the engine will start and run for about 1 second, then shut off.
^ If you turn the ignition switch to ON (II), then pause before turning to START (III), the starter will crank the engine, but it will not start.
Unlike the previous system, when a nonprogrammed key is used and the ignition switch is returned to LOCK (0), the indicator flashes 10 times to
indicate the system has reset.
Immobilizer-Keyless Control Unit
171
The immobilizer-keyless control unit is inside the bezel around the steering column. It uses electromagnetic induction to energize the transponder in
the key. There is no direct electrical connection. Once the transponder is energized, the key sends its ID code to the immobilizer-keyless control unit,
which checks the code against the codes stored in its memory. If the ID code matches, the control unit sends a unique serial code to the PCM, and
the engine starts. If the ID code does not match, no serial code is sent, and the engine does not start.
Powertrain Control Module (PCM)
The PCM is an integral part of the immobilizer system. When the PCM receives the unique serial code from the immobilizer-keyless control unit, it
communicates or handshakes" with the immobilizer-keyless control unit by sending back its own unique serial code. If the serial codes are mutually
recognized, the PCM energizes the fuel supply system so the engine can start.
ADDING AND DELETING KEYS
Vehicles originally come with two programmed master keys and one valet key. The immobilizer-keyless control unit accepts a total of six
transponder codes, so three more codes can be stored in its memory. Use the following procedures to add a key, to add multiple keys, to replace
programmed keys, or to clear the codes of lost keys.
Adding a Key
Use the HDS (Honda Diagnostic System) with Acura key blanks to add a key. Make sure you use only Acura key blanks. The HDS rewrites the
immobilizer-keyless control unit, storing the transponder code of the new key in the memory of the control unit.

STARTING THE ENGINE WITHOUT A PROGRAMMED IGNITION KEY
If the client is stranded because of lost ignition keys, you can still start the engine using a properly cut key blank and a VIN specific, five-digit
immobilizer brake code. This procedure is suitable when the client plans to drive the vehicle directly to an Acura dealership for repair, or the client
has the programmed ignition keys at home and plans to drive straight home. Advise the client to schedule an appointment to have the immobilizer
175
control unit receiver rewritten for the remaining ignition keys; this is needed to clear the transponder codes from the missing keys. If all programmed
ignition keys are lost, the immobilizer control unit must be rewritten to accept the new keys.
Preparation
NOTE:
Refer to the parts catalog for the correct P/Ns, and search by the VIN for the correct parts.
To start the engine without a programmed ignition key, you need these items:
^ Immobilizer Master Key Blank
or
^ Immobilizer Valet Key Blank
^ Key code for the vehicle
^ Tn-Code H.S. Key Cutter
^ Immobilizer Brake Code (this 5 digit code is available on the iN. Go to SERVICE, select Vehicle Information, then select Immobilizer Code
inquiry.)
Procedure
NOTE:
This procedure is only a temporary fix. When the engine is started, the immobilizer indicator stays on.
1. Use an appropriate key blank and the Tn-Code H.S. Key Cutter to cut a temporary ignition key (see the Tn-Code H.S. operating manual).
2. Release the parking brake.
3. Insert the temporary key into the ignition switch.
4. Turn the ignition switch to ON (II). Wait for the brake indicator bulb check to complete.
5. Enter the first digit of the five-digit immobilizer brake code by setting and releasing the parking brake the required number of times within 30
seconds. For example, if the first digit is four, set and release the parking brake four times.
NOTE:
You only need to apply the parking brake enough to actuate the parking brake switch; you don't need to fully engage the parking brake.
6. Turn the ignition switch to LOCK (0). This enters the digit into the PCM.
7. Repeat steps 2 thru 6 to enter the remaining four digits. When you turn the ignition switch to ON (II), the immobilizer indicator stays on. It stays
on even when the ignition switch is turned to LOCK (0).
8. Start the engine using the temporary key. The system allows the vehicle to be started for 10 minutes. After that, the entire procedure must be
repeated.
