6. Reconnect the connectors to the under-dash fuse/relay box, and do these input tests at the following connectors.
 If any test indicates a problem, find and correct the cause, then recheck the system.
 If all the input tests prove OK, the MICU must be faulty; replace the under-dash fuse/relay box.

With HDS
22-142 Keyless/Power Door Locks/Security System
Transmitter Test/Replacement
A
NOTE:
 If the doors unlock or lock with the transmitter, but the LED on the transmitter does not come on, the LED
is faulty; replace the transmitter.
 If any door is open, you cannot lock the doors with the transmitter.
 If you unlocked the doors with the transmitter, but do not open any of the doors within 30 seconds, the
doors relock automatically.
 The doors do not lock or unlock with the transmitter if the ignition key is inserted in the ignition switch.
1. Press the lock or unlock button five or six times to reset the transmitter.
 If the locks work, the transmitter is OK.
 If any of the transmitter buttons do not work, replace the transmitter, then do the transmitter
programming registration (see page 22-329).
 If the locks don’t work, go to step 2.
2. Connect the HDS to the data link connector.
3. Select the KEYLESS from the BODY ELECTRICAL menu, then enter the KEYLESS CHECK.
4. Press lock, unlock, trunk, or panic button and check the response on the screen of the HDS.
NOTE: The door lock actuators may or may not
cycle when receiving input from the transmitter.
 If KEYLESS ENTRY TRANSMITTER CODE IS RECEIVED is indicated, the transmitter is OK. Go
to keyless operation troubleshooting (see page
22-127).
 If DIFFERENT KEYLESS ENTRY TRANSMITTER CODE IS RECEIVED is indicated, the transmitter is
not registered to the vehicle, if necessary,
reprogram and register the transmitter (see page
22-329).
 If KEYLESS ENTRY TRANSMITTER CODE IS NOT RECEIVED is indicated, go to step 5. 5. Open the transmitter and check for water damage.
 If you find any water damage, replace thetransmitter, then reprogram and register the
transmitter (see page 22-329).
 If there is no water damage, go to step 6.
6. Replace the transmitter battery (A) with a new one, and press lock or unlock button and check the
receive condition on the screen of the HDS.
 If KEYLESS ENTRY TRANSMITTER CODE IS RECEIVED is indicated, the transmitter is OK.
 If KEYLESS ENTRY TRANSMITTER CODE IS NOT RECEIVED is indicated, go to step 7.
