Trouble Diagnoses
Alarm Trigger Feedback
To verify the last three triggers that activated the theft warning system, the Time Control Unit (TCU) can be
switched into Diagnostic Mode (see page EL-182 how to enter Diagnostic Mode).
Approximately 2 seconds after the TCU has finished flashing the hazard lamp to confirm that the Diagnostic
Mode has been successfully entered, the TCU will generate a short beep indicating the trigger that will be dis-
played. A single beep means the most recent trigger, three beeps means the oldest trigger. Following each
beep or group of beeps, the hazard lamp will flash to indicate the alarm trigger.
Source of Alarm Trigger Number (of flashes)
Driver's door lock status switch 1
Passenger door lock status switch 2
Rear door lock status switch 3
Ignition line 4
Driver's door open switch 5
Other door open switch 6
Trunk or back door open switch 8
Hood switch 9
Ultrasonic sensors 10
In case there have been no alarm triggers, there will be no indicator flashes between the audible signals. After
completing the alarm trigger feedback, the TCU will enter Diagnostic Mode as described on page EL-182.
Before continuing trouble diagnoses on the next page, perform the checks as mentioned in the table on page
EL-183.
