Factory Security System Doesn't Arm

APPLIES TO:
1998-02 Accord EX, 2001-03 Odyssey EX, 2003 Pilot EX

SERVICE TIP:
If the factory-installed security system doesn't arm in a test the keyless remote transmitter to make sure it locks and unlocks the doors the way it should. If it doesn't work right, refer to section 22 of the appropriate S/M, and repair the keyless remote transmitter problem before attempting to diagnose the security system. The vehicle will have these symptoms if the security system can't arm:

The taillights don't flash when you lock the doors with the keyless remote.

The horn doesn't sound the confirmation beep when you relock the doors with the keyless remote within 5 seconds.

The security LED on the door panel or in the gauge assembly doesn't flash when you lock the vehicle with either the keyless remote or the door key cylinder switch.



If the security system doesn't arm, check these switches in the order listed. The switches must be open (about 10 volts on the circuit) for the security system to set. If any of these switches or circuits are shorted (0 volts on the circuit), the security system can't set.
