TITLE:
Keyless Remote Unlocks But Doesn't Lock Doors

APPLIES TO:
1998-02 Accord EXs and SEs, 2001-03 Odyssey EXs, and 2003 Pilots

SERVICE TIP:
If the keyless remote transmitter unlocks the doors but doesn't lock them, troubleshoot the problem by following this procedure:

1. Lock and unlock the doors with each power door lock switch.

Do the doors lock and unlock OK?

YES - Go to step 2.

NO - Troubleshoot and correct the problem in the power door lock circuit.

2. Watch the dome light and the door open monitor in the gauge assembly.

Do the dome light and the door open indicator stay on at all times?

YES - Go to step 3.

NO - Do the security/multiplex system input tests in the appropriate service manual.

3. Check these switches and circuits:

- Driver's door switch
- Front passenger's door switch
- Left rear passenger's door switch
- Right rear passenger's door switch
- Tailgate switch (Odyssey or Pilot only)

NOTE: Each of the listed switches and its circuit must be open and have about 10 volts measured on the circuit for the keyless system to lock the doors. If a switch or wire is shorted to ground (0 volts measured on the circuit), the remote transmitter can't lock the doors, only unlock them.
