Diagnostic Test

WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

ACTIVE DTC
1. Turn the ignition on, engine not running.
2. With the scan tool, read DTCs.
  Is the DTC active?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to STANDARD PROCEDURE .
CHECK THE (N11) FPCM CONTROL CIRCUIT FOR A SHORT TO VOLTAGE
1. Leave the ignition on, engine not running.
2. Disconnect the FPCM harness connector.
3. Measure the voltage of the (N11) Control circuit at the FPCM harness connector.
  Does the voltage measure above 5.2v?
  
  Yes
  - Repair the (N11) FPCM Control circuit for a short to voltage.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 3
CHECK THE (N11) FPCM CONTROL CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the PCM C1 harness connector.
3. Measure the resistance between ground and the (N11) FPCM Control circuit at the FPCM harness connector.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Repair the (N11) FPCM Control circuit for a short to ground.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 4
CHECK THE (N11) FPCM CONTROL CIRCUIT FOR AN OPEN/HIGH RESISTANCE
1. Leave the ignition off.
2. Measure the resistance of the (N11) FPCM Control circuit between the FPCM harness connector and the PCM C1 harness connector.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Replace the Powertrain Control Module in accordance with the service information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Repair the (N11) FPCM Control circuit for an open or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
