00084 CHECK REMOTE ALARM LIGHT
This alarm may be activated with earlier software revisions, follow procedure for alarm 06001
CHECK LIGHT BAR.
00093 CHECK STARTUP BUZZER
• ACTIVATION: The Buzzer (B) circuit is shorted or open. (The Buzzer output from the microprocessor
[PCM-23 to 3MM15] is negative, so the circuit will not be shorted to ground, but is shorted either within
the Buzzer itself, or to a positive wire.)
• UNIT CONTROL: Alarm only.
• RESET CONDITION: Auto reset when Buzzer amp draw is normal, or alarm may be manually reset using
the display mounted keys or by turning the unit off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active
alarm should clear itself (refer to reset condition above). Operate the unit through the appropriate modes to see
if any active alarm occurs. Continue with the steps below as necessary.
CORRECTIVE ACTIONS:
1. Check Buzzer
a. Inspect Buzzer & wire connections. No damage or corrosion to buzzer.
b. Check resistance of buzzer. Cannot be open (infinite ohms) or shorted (Zero Ohms).
2. Check Buzzer Wiring - Inspect PCM sub-harness connector pins & terminals. (See wiring schematic
Section 10.3.) Verify there is no physical damage to harness, and no damage, moisture, or corrosion in
connectors.
3. Check Buzzer - Use Component Test Mode (Refer to Section 5.3.2) to test actual current draw of the
circuit. Buzzer provides audible signal. View current draw in Component Test Mode screen. Verify cur-
rent.
