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.

DTC IS ACTIVE
NOTE:
Diagnose and repair any system voltage or sensor supply voltage DTCs before continuing with this test.
1. Turn the ignition on.
2. With the scan tool, clear DTCs in the Powertrain Control Module (PCM).
3. With the scan tool, actuate the SRV Solenoid Control State.
4. With the scan tool, select View DTCs.
  Is the status Active for this DTC?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to STANDARD PROCEDURE .
SHORT RUNNER VALVE ASSEMBLY

1. Turn the ignition off.
2. Disconnect the Short Runner Valve harness connector.
3. Connect a jumper wire between the (Z908) Sensor Ground circuit and the (K237) SRV signal circuit in the Short Runner Valve Assembly harness connector.
4. Turn the ignition on.
5. With the scan tool, read the SRV PWM Feedback.
  NOTE:
  The SRV PWM Feedback should be less than 3% with the jumper wire in place.
  
  Is the SRV PWM Feedback less than 3%?
  
  Yes
  - Replace the Short Runner Valve in accordance with the Service Information. Refer to MANIFOLD, INTAKE, REMOVAL, 5.7L .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 3
    NOTE:
    Remove the jumper wire before continuing.

1. With the scan tool, actuate the Auto Shutdown (ASD) Relay Control State.
2. Using a 12-volt test light connected to ground, check the (F342) ASD Relay Output circuit in the Short Runner Valve harness connector.
  NOTE:
  The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.
  
  Is the test light illuminated and bright?
  
  Yes
  - Go To 4
  No
  - Repair the (F342) ASD Relay Output circuit for an open circuit or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
(Z908) SRV GROUND CIRCUIT OPEN CIRCUIT OR HIGH RESISTANCE

1. Turn the ignition off.
2. Disconnect the Powertrain Control Module (PCM) C2 harness connector.
3. Measure the resistance of the (Z908) SRV ground circuit in the Short Runner Valve harness connector to ground.
  Is the resistance less than 5.0 Ohms?
  
  Yes
  - Go To 5
  No
  - Repair the (Z908) SRV ground circuit for an open circuit or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
(K237) SRV SIGNAL CIRCUIT SHORTED TO VOLTAGE

1. Turn the ignition on.
2. Measure the voltage of the (K237) SRV signal circuit at the SRV harness connector.
  Is there any voltage present?
  
  Yes
  - Repair the (K237) SRV signal circuit for a short to voltage.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 6
(K237) SRV SIGNAL CIRCUIT OPEN OR HIGH RESISTANCE
2. Turn the ignition off.
3. Leave the SRV harness connector and the PCM C2 harness connector disconnected.
5. Measure the resistance of the (K237) SRV signal circuit between the SRV harness connector and the PCM C2 harness connector.
  Is the resistance less than 5.0 Ohms?
  
  Yes
  - Go To 7
  No
  - Repair the (K237) SRV signal circuit for an open or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Short Runner Valve Assembly and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals.
4. Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
5. Look for the data to change or for the DTC to reset during the wiggle test.
6. Perform any Technical Service Bulletins that may apply.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
