FLASH CODE:
13
DDR DISPLAY:
COOLANT LEVEL SENSOR INPUT VOLTAGE LOW
SAE J1587 CODE:
PID: 111 FMI: 4
Indicates that the Coolant Level Sensor (CLS) input to the ECM has dropped below 5% (normally < 0.25 volts) of
the sensor supply voltage. This diagnostic condition is typically:
(1)
sensor signal is shorted to the sensor return circuit or to ground
(2)
sensor +5 volt supply is shorted to sensor return circuit or to ground
The DDEC III ECM supplies a switched ground to the AUXILIARY OUTPUT #8 circuit to turn ON the function
assigned.
FLASH CODE:
14
DDR DISPLAY:
COOLANT TEMP SENSOR INPUT VOLTAGE HIGH
SAE J1587 CODE:
PID: 110 FMI: 3
Indicates that the engine Coolant Temperature Sensor (CTS) input to the ECM has exceeded 95% (normally 4.75
volts) of the sensor supply voltage. NOTE: This code will only be logged during warm engine operation. This
diagnostic condition is typically:
(1)
open sensor signal circuit
(2)
open sensor return circuit
(3)
sensor signal circuit Is shorted to the sens or +5 volt supply
FLASH CODE:
14
DDR DISPLAY:
OIL TEMP SENSOR INPUT VOLTAGE HIGH
SAE J1587 CODE:
PID: 175 FMI: 3
Indicates that the engine Oil Temperature Sensor (OTS) input to the ECM has exceeded 95% (normally > 4.75 volts)
of the sensor supply voltage. NOTE: This code will only be logged during warm engine operation. This diagnostic
condition is typically:
(1)
open sensor signal circuit
(2)
open sensor return circuit
(2)
sensor signal circuit is shorted to the sensor +5 volt supply
FLASH CODE:
14
DDR DISPLAY:
INTER COOLER SENSOR INPUT VOLTAGE HIGH
SAE J1587 CODE:
PID: 052 FMI: 3
Indicates that the engine Intercooler Temperature Sensor input to the ECM has exceeded 95% (normally > 4.75
volts) of the sensor supply voltage. NOTE: This code will only be logged during warm engine operation. This
diagnostic condition is typically:
(1)
open sensor signal circuit
(2)
open sensor return circuit
(2)
sensor signal circuit is shorted to the sensor +5 volt supply
FLASH CODE:
15
DDR DISPLAY:
COOLANT TEMP SENSOR INPUT VOLTAGE LOW
SAE J1587 CODE:
PID: 110 FMI: 4
Indicates that the engine Coolant Temperature Sensor (CTS) input to the ECM has dropped below 5% (normally <
0.25 volts) of the sensor supply voltage. This diagnostic condition is typically:
(1)
sensor signal circuit is shorted to sensor return or to ground
(2)
sensor +5 volt supply is shorted to sensor return circuit or to ground
