TM 9-2320-364-20-1
2-14. DDEC III/IV TROUBLESHOOTING (CONT).
Section IV. TROUBLESHOOTING CHARTS (Cont.)
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 sensor +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
(3) 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
FLASH CODE:
15
DDR DISPLAY:
OIL TEMP SENSOR INPUT VOLTAGE LOW
SAE J1587 CODE:
PID: 175 FMI: 4
Indicates that the engine Oil Temperature Sensor (OTS) 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
FLASH CODE:
21
DDR DISPLAY:
THROTTLE SENSOR INPUT VOLTAGE HIGH
SAE J1587 CODE:
PID: 91 FMI: 3
Indicates that the Throttle Position Sensor (TPS) input to the ECM has exceeded 95% (normally > 4.75 volts) of
the sensor supply voltage.  This diagnostic condition is typically:
(1) open sensor return circuit
(2) sensor signal circuit is shorted to the sensor +5 volt supply
