00126 CHECK FUEL SENSOR CIRCUIT
ACTIVATION: The fuel level sensor is configured “YES” and the reading (in the Unit Data) is less than 2%
for 30 seconds.
UNIT CONTROL: Engine Operation: Alarm Only.
Electric Operation: This alarm does not activate in electric operation.
RESET CONDITION: Auto reset when fuel level is sensed above 4% for 30 seconds 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 For Low Fuel Level
Check fuel level in tank. Add fuel as needed.
2. Check Sensor Fuse & Wiring
a. Check Fuse F8 Verify correct fuse, and check fuse holder for damage, see Figure 2.5. Replace
fuse as required. Clear alarms, restart and check for repeat alarm(s).
b. Inspect wiring from at PCM22, and 2MM24. Verify there is no physical damage to harness, and no
damage, moisture, or corrosion in connectors.
c. Perform sensor check procedure. Refer to Section 8.5.7.
NOTE
If new sensor is not available, the sensor may be configured OFF temporarily. Refer to Section
5.2.3 - Configurations.
00127 CHECK SUCTION TEMP SENSOR
ACTIVATION: Compressor Suction Temperature Sensor (CST) is not within the range of 53 to +158°F
(47 to +70° C.)
UNIT CONTROL: Engine and Electric Operation: Alarm only. Control of Superheat will switch to supply
air temperature sensor.
RESET CONDITION: Auto reset 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 Sensor
a. Inspect sensor & connector. Verify there is no damage to sensor, and no damage, moisture, or cor-
rosion in connector.
b. Check sensor resistance (Refer to Note 3 in Notes Section, page 7-2.) 10,000 Ohms @ 77°F
(25°C.) See Table 8–3 for complete table of temperatures and resistance values.
2. Check Sensor Wiring
a. Inspect connector pins & terminals at sensor and connector 2MM. (See wiring schematic
Section
10.3
) Verify there is no physical damage to harness, and no damage, moisture, or corrosion in con-
nectors.
b. Place the system in PC Mode. Refer to Note 2 in Notes Section, page 7-2. Disconnect sensor
from harness. Check for 3.0 ± 0.1 VDC volts at harness plug between pins. This verifies micropro-
cessor output and wiring connections to the sensor.
