4360-4 3105-4
Aftertreatment #1 SCR Cata-
lyst Intake Gas Temperature :
Voltage Below Normal
The ECM detects the following conditions:
The signal voltage from the SCR inlet temperature sensor is less than 0.2
VDC for more than 8 seconds.
An active diagnostic code will be generated after 8 seconds. The diagnostic
code will be logged if the engine has been operating for more than 7 minutes.
“Voltage Below Normal” will be displayed next to the status for “SCR Inlet Tem-
perature” on the electronic service tool.
4360-20 3105-20
Aftertreatment #1 SCR Cata-
lyst Intake Gas Temperature :
Data Drifted High
The ECM detects the following conditions:
The SCR inlet temperature sensor has probably failed in range.
An active diagnostic code will be generated after 8 seconds. The diagnostic
code will be logged if the engine has been operating for more than 7 minutes.
“Data Drifted High” will be displayed next to the status for “SCR Inlet Tempera-
ture” on the electronic service tool.
4765-3 3956-3
Aftertreatment #1 Diesel Oxi-
dation Catalyst Intake Gas
Temperature : Voltage Above
Normal
The ECM detects the following conditions:
The signal voltage from the DOC inlet temperature sensor is greater than 4.95
VDC for more than 8 seconds.
An active diagnostic code will be generated after 8 seconds. The diagnostic
code will be logged if the engine has been operating for more than 7 minutes.
“Voltage Above Normal” will be displayed next to the status for “DOC Inlet
Temperature” on the electronic service tool.
4765-4 3956-4
Aftertreatment #1 Diesel Oxi-
dation Catalyst Intake Gas
Temperature : Voltage Below
Normal
The ECM detects the following conditions:
The signal voltage from the DOC inlet temperature sensor is less than 0.2
VDC for more than 8 seconds.
An active diagnostic code will be generated after 8 seconds. The diagnostic
code will be logged if the engine has been operating for more than 7 minutes.
“Voltage Below Normal” will be displayed next to the status for “DOC Inlet
Temperature” on the electronic service tool.
7441-3 4648-3
Aftertreatment Ambient Air
Temperature : Voltage Above
Normal
The ECM detects the following conditions:
The signal voltage from the aftertreatment ambient air temperature sensor is
greater than 4.95 VDC for more than 8 seconds.
An active diagnostic code will be generated after 8 seconds. The diagnostic
code will be logged if the engine has been operating for more than 7 minutes.
“Voltage Above Normal” will be displayed next to the status for “Aftertreatment
Ambient Air Temperature” on the electronic service tool.
7441-4 4648-4
Aftertreatment Ambient Air
Temperature Sensor : Voltage
Below Normal
The ECM detects the following conditions:
The signal voltage from the aftertreatment ambient air temperature sensor is
less than 0.2 VDC for more than 8 seconds.
An active diagnostic code will be generated after 8 seconds. The diagnostic
code will be logged if the engine has been operating for more than 7 minutes.
“Voltage Below Normal” will be displayed next to the status for “Aftertreatment
Ambient Air Temperature” on the electronic service tool.
Follow the troubleshooting procedure in order to identify the root cause of the fault.
