Diagnostic Test

WARNING: This page is about a different car, the 2014 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR ACTIVE DTC 
    1. Ignition on, engine not running.
    2. With the scan tool, erase DTCs in the Powertrain Control Module (PCM).
    3. Start the engine and allow to reach operating temperature.
    4. Test drive the vehicle during normal operating conditions.
    5. With the scan tool, read the PCM DTCs.

      Did this DTC return?

      Yes 

      • Go To  2

      No 

      • Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT DTC .
  2. CHECK THE (K414) DEF LEVEL/TEMPERATURE SIGNAL FOR A SHORT TO VOLTAGE 
    1. Turn the ignition off.
    2. Disconnect the DEF Pump-Level/Temperature Sensor Assembly harness connector.
    3. Disconnect the PCM C1 harness connector.
    4. Measure the resistance between the (K414) Def Level/Temperature Signal circuit and all other circuits on the PCM C1 harness connector at the PCM C1 harness connector.

      Is the resistance above 10k Ohms?

      Yes 

      • Go To  3

      No 

      • Repair the (K414) Def Level/Temperature Signal circuit for a short to the circuit that measured less than 10k Ohms.
      • Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  3. CHECK THE DEF LEVEL/TEMPERATURE SIGNAL FOR AN OPEN/HIGH RESISTANCE 
    1. Measure the resistance of the (K414) Def Level/Temperature Signal circuit between the DEF Pump-Level/Temperature Sensor Assembly harness connector and the PCM C1 harness connector.

      Is the resistance above 5.0 Ohms?

      Yes 

      • Repair the (K414) Def Level/Temperature Signal circuit for an open/high resistance.
      • Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .

      No 

      • Go To  4
  4. DEF PUMP-LEVEL/TEMPERATURE SENSOR ASSEMBLY 
    1. Turn the ignition off.
    2. Replace the DEF Pump-Level/Temperature Sensor Assembly in accordance with the service information.
    3. Turn the ignition on.
    4. With the scan tool, erase PCM DTCs.
    5. Start the engine and allow to reach operating temperature.
    6. Test drive the vehicle during normal operating conditions.
    7. With the scan tool, read PCM DTCs.

      Does the scan tool display this DTC?

      Yes 

      • Replace the Powertrain Control Module in accordance with the service information. Refer to REMOVAL .
      • Perform the PCM VERIFICATION TEST. Refer to PCM VERIFICATION TEST .

      No
