(Supersedes 06-033, dated February 20, 2009; see REVISION SUMMARY)
REVISION SUMMARY
This service bulletin has been revised extensively. American Honda recommends that you review the entire bulletin.
BACKGROUND
All 2007-09 MDXs and 2007-12 RDXs have a Type 6 GEN4 immobilizer system that disables the vehicle unless a programmed ignition key is used.
The transponder in the key or keyless transmitter uses a rolling-type code instead of a set code.
In this service bulletin, a programmed ignition key refers to a transponder-type key 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 and runs for one second and stalls.
This service bulletin covers:
^ Immobilizer system components
^ Immobilizer transponder keys and keyless transmitter descriptions
^ System description
^ Adding and deleting keys or keyless transmitters
^ Replacing the immobilizer-keyless control unit
^ Replacing the PCM
187
^ Replacing the under-dash fuse/relay box (MICU)
^ Starting the engine without a programmed ignition key
^ Troubleshooting the immobilizer system
For more information on the immobilizer system, refer to the Body Electrical section of the appropriate service manual.
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:
^ Immobilizer transponder keys
^ Immobilizer system indicator
^ Immobilizer-keyless control unit
^ PCM
^ Under-dash fuse/relay box (MICU) with built-in IMOES unit and 1-wire B-CAN communication
IMMOBILIZER TRANSPONDER KEYS AND
KEYLESS TRANSMITTER DESCRIPTIONS
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.
When you need to cut a new or duplicate key, use the appropriate tool from the Honda Tool and Equipment Program. Call or on the Interactive
Network (iN), click on Service > Quick Links > Tool and Equipment Program.
Because of the rolling code characteristics of the Type 6 immobilizer system, you cannot use the Ilco Immobilizer Key Code Duplicator or Ilco
programmable (T5) key blanks with this system.
188
The immobilizer transponder does not contain batteries or other serviceable parts. The master keys have a battery-operated remote transmitter built
into the grip for the keyless functions.
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 and then goes off. At this point, the engine can be started by turning the ignition switch to START (III).
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
189
The immobilizer-keyless control unit is inside the bezel around the steering column. It uses electromagnetic induction to energize the electronic
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 and the ignition system so the engine can start.
Disclaimer
Adding and Deleting Keys or Keyless Transmitters
Vehicles originally come with three programmed ignition keys. 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 key blanks with a V stamped on the shank.

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
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
^ Suitable key cutting machine
^ 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 a suitable key cutting machine.
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.

UPDATING TIPS AND PRECAUTIONS
^ If you're updating a control module/unit on a new vehicle, make sure all its fuses were installed at TQI.
^ To prevent control unit/module damage, do not operate anything electrical (audio system, brakes, A/C, power windows, moonroof, etc.) during
the update.
^ If the Database Update listed in the service bulletin is later than that shown by the software, please see the software installation procedure in the
following two documents in Tool Information on ISIS (go to General Publication, then Tool Information):
^ Installation Instructions for HDS PC Software
^ MVCI User Guide (see HDS MVCI Firmware Update section)
^ Do not connect an additional power supply to the MVCI when it is connected to the vehicle; power is supplied through the DLC.
^ To ensure that the control module/unit is not permanently damaged during updating, verify that the vehicles 12-volt battery is fully charged
202
before starting an update.
NOTE:
If the vehicles 12-volt battery drops below 10 volts during the update, the programming status bar may go past 100 percent, or the updating
tool may display an error message.
^ If you have a problem during an update (D4/immobilizer indicator flashes, update tool freezes, etc.), you can minimize the chances of damaging
the control unit/module by doing one or more of these actions:
- CRITICAL: Keep the ignition switch in ON (II).
- Connect a jumper battery (DO NOT connect a battery charger).
- Disconnect the updating tool from the vehicles DLC.
- Reboot the updating tool.
- Reconnect the updating tool to the vehicles DLC, and retry the updating procedure.
HOW TO CHECK IF THE MVCI IS UPDATED
Whenever there is an HDS software update, there will
be an update for the MVCI. After updating the HDS,
update the MVCI. For more information on how to
update the MVCI, refer to the Modular Vehicle
Communication Interface (MVCI) User Guide on ISIS
under General Publications > Tool Information.
To check that the MVCI has the latest database
installed, go to the iN home page and click on
SERVICE > Service Bay > Diagnostic Tools
Software Versions. The most recent version of the
database is listed under CM Update database.
