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-218 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.

completing the alarm trigger feedback, the TCU will enter Diagnostic Mode as described on page EL-218.
