Alarm List
Alarm Code and Text Alarm Type–Cause Diagnostics
101.
WATER TEMPERATURE
HIGH Delayed Restart Alarm–Engine is
running and water temperature is above
107 C (225 F) for 25 seconds.
• Engine then stops and then attempts
to restart.
1. Check for cause of engine
overheating:
• Check engine coolant level.
• Check water pump belt.
• Check radiator for airflow and
coolant flow restrictions.
2. Check for faulty water temperature
sensor.
102.
FAILED TO CRANK Delayed Restart Alarm–Engine failed to
crank.
Becomes a Shutdown Alarm when
number of restart attempts is greater
than number of “Crank Restarts” set in
Configuration Menu.
1. Check battery, battery cables, and
starter.
2. Check 8S circuit.
3. Check Start Relay.
4. Check for seized engine or alternator.
103.
FAILED TO START Delayed Restart Alarm–Engine failed to
crank.
Becomes a Shutdown Alarm when
number of restart attempts is greater
than number of “Crank Restarts” set in
Configuration Menu.
1. Check fuel level.
2. Check fuel solenoid, fuel pump, and
fuel system both electrically and
mechanically.
3. In cold ambient temperatures check
for fuel gelling.
4. Check for restricted air cleaner or air
intake system.
5. Check intake air heater.
104.
RL2 (FUEL H) FEEDBACK
FAILURE Shutdown Alarm–No feedback when
relay is energized, or feedback when
relay is not energized. 1. Check RL2 (Fuel Hold) relay.
2. Check 8D circuit.
105.
RL1 (FUEL P) FEEDBACK
FAILURE Shutdown Alarm–No feedback when
relay is energized, or feedback when
relay is not energized. 1. Check RL1 (Fuel Pull) relay.
2. Check 8DP circuit.
106.
RL5 (STARTER)
FEEDBACK FAILURE Shutdown Alarm–No feedback when
relay is energized, or feedback when
relay is not energized. 1. Check RL5 (Start) relay.
2. Check SR, PSR, and FSR circuits.
107.
EXTERNAL OVERLOAD Shutdown Alarm–Message 122 has
occurred 3 times. 1. Unplug load and attempt restart.
2. Check alternator field circuit.
3. Check alternator output circuit.
108.
ENGINE NOT RUNNING
REASON UNKNOWN Delayed Restart Alarm–Input from Low
Oil Pressure Switch is low (grounded)
and RPM equals 0 when engine should
be running.
• Engine will attempt to restart in 20
minutes.
1. Check fuel level.
2. Check fuel solenoid, fuel pump, and
fuel system both electrically and
mechanically.
3. In cold ambient temperatures check
for fuel gelling.
4. Check for seized engine or alternator.
