NOTE:
• The immobilizer system can store up to five key codes.
• If it is necessary to rewrite the immobilizer control unit to learn a new key, the dealer needs the customer's vehicle, all
its master keys and valet keys, its learning key, and the Honda PGM Tester equipped with an immobilizer program
card. Any key that is not learned during rewriting will no longer start the engine.
• If the customer has lost his key, and cannot start the engine, contact Acura Customer Relations or Roadside Assistance.
Before Testing:
• Due to the action of the immobilizer system, the engine takes slightly more time to start than engines of vehicle
without an immobilizer system.
• When the system is normal, and the proper key is inserted, the indicator light comes on for 2 seconds, then it will go
off.
• If the indicator starts to blink after 2 seconds, or if the engine does not start, repeat the starting procedure.
If the engine still does not start, perform the immobilizer control unit input test and transponder and immobilizer
receiver test.
• If all the input tests and transponder and immobilizer receiver test prove OK, check the PCM (see
If the PCM is OK, the immobilizer control unit must be faulty; replace the immobilizer control unit, master key and
learning key together, and then rewrite the PCM with the Honda PGM Tester.
If the PCM is faulty, substitute a known-good PCM, and recheck. However, since the known-good PCM has a
different code stored into it, it must be rewritten with the Honda PGM Tester. Otherwise, the engine will not start.
