Diagnostic Test

WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

ENGINE COOLANT INSPECTION
NOTE: This DTC will set if the engine cools quicker than is should compared to engine off times. If the customer washed a hot engine with the engine off, a One Trip Failure will set. If the vehicle is parked in a highly ventilated area or has a large fan blowing on it which might cause the engine to cool quicker than expected this DTC may set.

WARNING: Do not remove or loosen the radiator cap with the system hot and under pressure. Serious burns from coolant can occur.
1. Turn the ignition off.
2. Allow the engine to cool enough to allow the pressure in the coolant system to drop enough to safely remove the radiator cap.
3. Check the coolant level and condition.
  Is the engine coolant level filled to the proper level?
  
  Yes
  - Go to step 2
  No
  - Add the appropriate type and amount of engine coolant. Refer to Cooling - Standard Procedure
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
PCM
1. Turn the ignition on.
2. With the scan tool under PCM/NGC Data Display, locate the Ignition Off Time value.
3. While monitoring a stop watch, turn the Ignition off for 10 minutes, watch the stop watch for those 10 minutes, and then turn the Ignition on.
4. With the scan tool under Data Functions, check the Ignition Off Time value again.
  Does the Ignition Time Off value on the scan tool match the actual time you had the Ignition off on the stop watch?
  
  Yes
