ECU Door “Ajar” Alarm - d02
When “d02” displays on the ECU, there is a door intrusion condition. Two scenarios cause d02 to be displayed.
•
A door is left open for more than 30 minutes (a normal condition).
•
A broken door intrusion switch or an open in the door intrusion switch wiring (a fault condition).
Scenario 1 (Normal Condition)
No troubleshooting required. A door was simply left open for more than 30 minutes. Close the door, or momentarily depress the
Audible Alarm Cutoff / Maintenance / Reset pushbutton located on the ECU to cancel the intrusion alarm and silence the audible
alarm for another 30 minutes.
Scenario 2 (Fault Condition - Broken Door Intrusion Switch
or an Open in the Door Intrusion Switch Wiring)
If the door has been closed and there is an audible alarm active, you have a broken door intrusion switch or an open in the door
intrusion switch wiring.
