00133 CHECK REMOTE TEMP SENSOR 1
00134 CHECK REMOTE TEMP SENSOR 2
00135 CHECK REMOTE TEMP SENSOR 3
• ACTIVATION: Remote Temperature Sensor (REMSN1, REMSN2 or REMSN3) is not within the range of
-53 to +158°F (-47 to +70°C.)
• UNIT CONTROL: Engine and Electric Operation: Alarm only.
• RESET CONDITION: Auto Reset when Remote Temperature Sensor is in range or, alarm may be manu-
ally reset via keypad 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:
IF A SENSOR IS INSTALLED
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). Refer to Table 8–3 for chart of resistances for different sensors.
2. Check Sensor Wiring
a. Inspect connector pins & terminals at sensor, REM connector and 2CCB. (See wiring schematic
Section 10.3) Verify there is no physical damage to harness, and no damage, moisture, or corro-
sion in connectors.
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 sensor.
IF A SENSOR IS NOT INSTALLED
1. Check Configurations
Any switch/sensor that is not present in the unit should not be Configured “ON”. Correct Configurations.
2. Check REM Connector
Locate and inspect 10 position connector for optional sensors and switches. (See wiring schematic
Section 10.3). Connector must have cap on, no corrosion or moisture inside connector. If there is a
problem with the connector and there are no remote sensors or switches in the unit, the connector
may be removed and each individual wire separated from the others, terminated and insulated with
heat shrink.
