2630-3 3372-3
Engine Charge Air Cooler Out-
let Temperature : Voltage
Above Normal
The ECM detects the following conditions:
The signal voltage from the ATAAC outlet 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 “ATAAC Tem-
perature” on the electronic service tool.
2630-4 3372-4
Engine Charge Air Cooler Out-
let Temperature : Voltage Be-
low Normal
The ECM detects the following conditions:
The signal voltage from the ATAAC outlet 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 “ATAAC Tem-
perature” on the electronic service tool.
3242-3 2452-3
Aftertreatment #1 DPF Intake
Gas Temperature : Voltage
Above Normal
The ECM detects the following conditions:
The signal voltage from the DPF 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 “DPF Inlet Tem-
perature” on the electronic service tool.
3242-4 2452-4
Aftertreatment #1 DPF Intake
Gas Temperature : Voltage Be-
low Normal
The ECM detects the following conditions:
The signal voltage from the DPF 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 “DPF Inlet Tem-
perature” on the electronic service tool.
4360-3 3105-3
Aftertreatment #1 SCR Cata-
lyst Intake Gas Temperature :
Voltage Above Normal
The ECM detects the following conditions:
The signal voltage from the SCR 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 “SCR Inlet
Temperature” on the electronic service tool.
