1. Remove the driver’s door panel (see page 20-7).
2. Disconnect the 10P connector (A) from the actuator
(B).
3. Check for continuity between the terminals.  There should be continuity between terminalsNo. 6 and No. 5 when the door lock knob switch
is in the LOCK position and no continuity when
the switch is in the UNLOCK position.
 There should be continuity between terminals No. 7 and No. 5 when the door lock knob switch
is in the UNLOCK position and no continuity
when the switch is in the LOCK position.
4. If the continuity is not as specified, replace the door lock actuator. 1. Remove the passenger’s door panel (see page
20-7).
2. Disconnect the 10P connector (A) from the actuator (B).
3. Check for continuity between the terminals. There should be continuity between terminals
No. 8 No. 7 and No. 10 No. 5 when the
door lock knob switch in the UNLOCK position and
no continuity when the switch is in the LOCK
position. : Left rear door
4. If the continuity is not specified, replace the door lock actuator.

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.

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
system registration (see page 22-329).
 If KEYLESS ENTRY TRANSMITTER CODE IS NOT RECEIVED is indicated, the immobilizer-keyless
control unit is faulty, replace it and do the
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.

4. Replace the transmitter battery (A) with a new one,
and try to lock and unlock the doors with the
transmitter by pressing the lock or unlock button
five or six times.
 If the doors lock and unlock, the transmitter is OK.
 If the doors don’t lock and unlock, go to step 5.
5. Reprogram and register the transmitter (see page 22-329), then try to lock and unlock the doors.
 If the doors lock and unlock, the transmitter is OK.
 If the doors don’t lock and unlock, substitute a known-good transmitter and recheck (see page
22-329). If still not operating, replace the
immobilizer-keyless control unit.

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.
