7. Use a different known-good keyless transmitterand repeat steps 3 and 4.
NOTE: The keyless transmitter does not need to be
programmed to the vehicle for this test.
 If (DIFFERENT) KEYLESS ENTRY TRANSMITTER CODE IS RECEIVED is indicated, replace the
keyless transmitter and do the immobilizer

immobilizer system registration (see page
22-329).
NOTE: As the keyless transmitter is combined with
the immobilizer transponder, when the
transponder is registered by the HDS, the keyless
transmitter programming is completed
automatically. 1. Start the engine.
 If the engine does not start, go to the immobilizersymptom troubleshooting (see page 22-323).
 If the engine starts, go to step 2.
2. Press the lock or unlock button five or six times to reset the transmitter.
 If the locks work, the transmitter is OK.
 If the locks don’t work, go to step 3.
3. Open the transmitter and check for water damage.  If you find any water damage, replace thetransmitter.
 If there is no water damage, go to step 4.
