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:
15
DDR DISPLAY:
INTERCOOLER SENSOR INPUT VOLTAGE LOW
SAE J1587 CODE:
PID: 052 FMI: 4
Indicates that the engine Intercooler Temperature Sensor 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:
16
DDR DISPLAY:
COOLANT LEVEL SENSOR INPUT VOLTAGE HIGH
SAE J1587 CODE:
PID: 111 FMI: 3
Indicates that the Coolant Level Sensor (CLS) input to the ECM has exceeded 95% (normally > 4.75 volts) of the
sensor supply voltage. 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:
17
DDR DISPLAY:
BYPASS POSITION SENS INPUT VOLTAGE HIGH
SAE J1587 CODE:
PID: 72 FMI: 3
Indicates that the engine Blower Bypass Position Sensor 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
FLASH CODE:
18
DDR DISPLAY:
BYPASS POSITION SENS INPUT VOLTAGE LOW
SAE J1587 CODE:
PID: 72 FMI: 4
Indicates that the engine Blower Bypass Position Sensor input to the ECM has dropped below 5% (normally < 0.25
volts) of the sensor supply voltage. This diagnostic condition is typically:
(1)
open sensor signal circuit
(2)
open sensor +5 volt supply circuit
(3)
sensor signal is shorted to the sensor return circuit or ground
(4)
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
