TITLE:
Tripped Sensor Warning Feature Can Help You Troubleshoot Accessory Security System
APPLIES TO:
1998-02 Accords, 1996-00 Civics, 1997-01 CR-Vs, 1998-03 Odysseys, and 1997-01 Preludes with the Honda accessory security system installed.
SERVICE TIP:
The accessory security system has a cool feature that lets you know if there was a security system violation, what sensor was tripped the last time the system rearmed itself, and which sensor(s) triggered the current violation.
If the security system sensed a security violation and then rearmed itself, the tripped sensor warning gives these indications:
- The status LED blinks twice per second.
- If the beep (chirp) is on, the system beeps three times when you unlock the door with the remote transmitter.
- The parking lights flash three times when you unlock the door with the remote transmitter.
When you disarm a security system that's just been violated, the status LED can show you which sensor was tripped. If you're diagnosing the
system, this can help you pinpoint what you need to check. To make the status LED blink the code of the tripped sensor(s), press the disarm switch three times within 5 seconds of disarming the system. Then count the number of times the LED blinks, and match the number of blinks to the appropriate sensor listed in this table:
Here are two examples of how the status LED would blink:
- If the trunk sensor was tripped, the status LED blinks twice, pauses, and then repeats the sequence for 1 minute.
- If two sensors were tripped, such as the door and the trunk, the status LED blinks once (door), pauses, blinks twice (trunk), pauses, and then repeats the sequence.
The last tripped sensor indication is stored in the control unit's memory when the security system is disarmed, but you can still retrieve the info with this procedure:
1. With a remote transmitter in hand, sit in the vehicle with the doors, trunk, and hood closed. If the ignition key is in the ignition switch, remove the key.
2. Press and hold the disarm switch.
3. Within 3 seconds, press the LOCK button on the remote transmitter and then the UNLOCK button.
4. Release the disarm switch. The status LED now blinks to indicate the last sensor that was tripped.
Don't violate the security system on purpose before retrieving the last tripped sensor. If you do this, your violation then gets recorded in the control unit's memory as the last tripped sensor.
