Aftertreatment #2 DEF Controller #2 : Failure The #2 intake NOx sensor heater cannot generate enough heat or the power supply is intermittent. Note: Turn the keyswitch to the OFF position before connecting or disconnecting these components.If the Cat® Electronic Technician (ET) will not communicate with the Electronic Control Module (ECM), refer to Troubleshooting, "Electronic Service Tool Does Not Communicate" before you begin this procedure. The procedure verifies that electrical power is being supplied to the ECM and to the service tool connector.The data links are used to communicate information between the engine ECM and other control modules that are a part of the application. Cat ET also communicates with the ECM via the data links.The service tool connector contains connections for electrical power and for the data links.When the keyswitch is in the OFF position, Cat ET may communicate with the ECM. However, the communications may be disrupted and the communications may require frequent reconnection. To avoid this problem, place the keyswitch in the ON position when Cat ET is being used.Cat ET may display the following error message:"The version of the ECM is not recognized and the integrity of the changed parameters and displayed data is not guaranteed."This message indicates that one of the following conditions exist:
The flash file in the ECM is newer than the version of Cat ET.
The latest version of Cat ET has not been installed.

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® ET to the service tool connector.
B. Determine if a code is active or logged.
Codes
Result: A -11 code is active or logged.
Proceed to Test Step 2.
Result: A 3360-12, 3820-12, 4450-12, 4577-12, 7538-12, 4794-12, 7539-12, or 4798-12 code is active or logged.
Proceed to Test Step 4.
Result: A -12 code listed above is active or logged.
Repair: Replace the failed NOx sensor. Refer to Special Instruction, REHS8151 for special handling instructions.
Proceed to Test Step 5.
2. Inspect the Electrical Connectors and the Wiring
A. Turn the keyswitch to OFF.
B. Thoroughly inspect the connectors. Refer to Troubleshooting, "Electrical Connectors-Inspect" for additional information.
C. Perform a 45 N (10 lb) pull test on the connector wires.
D. Check the harness for abrasions and pinch points.
Connectors and Wiring
Result: The connectors and wiring appear to be OK.
Proceed to Test Step 3.
Result: There is a problem with the connectors and/or wiring.
Repair: Repair or replace the connectors or wiring. Ensure that all the seals are properly in place and ensure that the connectors are coupled.
Note: The Diesel Exhaust Fluid Control Unit (DCU) connector is not serviceable.
If the problem is not resolved, proceed to Test Step 3.
3. Check the Voltage to the Affected Sensor
A. Disconnect the affected sensor from the wiring harness.
B. Turn the keyswitch to ON.
C. Measure the voltage on the wiring harness connector between the following:
- +Battery (supply) and -Battery (return)
Battery Voltage
Result: The measured voltage is equal to battery voltage.
Repair: Replace the failed NOx sensor. Refer to Special Instruction, REHS8151 for special handling instructions.
Proceed to Test Step 5.
Result: The measured voltage is not equal to battery voltage.
Repair: There is a problem with an intermittent battery supply. Check the power supply to the affected sensor.
If the problem is not resolved, proceed to Test Step 5.
4. Perform the "DEF Dosing Control Module Reset"
A. Connect Cat ET.
B. Select the "Selective Catalyst Reduction System".
C. Use Cat ET to perform the following diagnostic test:
- DEF Dosing Control Module Key Switch Line Test
Reset
Result: A 3360-12, 3820-12, 4450-12, 4577-12, 7538-12, 4794-12, 7539-12, or 4798-12 code is active or logged.
