Diagnostic Test

WARNING: This page is about a different car, the 2015 RAM 3500 HD and 2015 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

CHECK FOR AN ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, erase DTCs in the Powertrain Control Module (PCM).
3. With the scan tool, actuate the SRV Solenoid Control State.
4. With the scan tool, read DTCs.
  Is the DTC active?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
CHECK THE (F342) ASD RELAY OUTPUT CIRCUIT FOR AN OPEN OR HIGH RESISTANCE

1. Turn the ignition off.
2. Disconnect the Short Runner Valve Assembly harness connector.
3. Turn the ignition on.
4. With the scan tool, actuate the Auto Shutdown (ASD) Relay Control State.
5. Using a 12-volt test light connected to ground, check the (F342) ASD Relay Output circuit in the Short Runner Valve Assembly 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 3
  No
  - Repair the (F342) ASD Relay Output circuit for an open circuit or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK THE (Z908) SRV GROUND CIRCUIT FOR AN OPEN OR HIGH RESISTANCE

1. Turn the ignition off.
2. Measure the resistance of the (Z908) SRV ground circuit in the Short Runner Valve Assembly harness connector to ground.
  Is the resistance less than 5.0 Ohms?
  
  Yes
  - Go To 4
  No
  - Repair the (Z908) SRV ground circuit for an open circuit or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
SHORT RUNNER VALVE ASSEMBLY

1. Turn the ignition on.
2. With the scan tool, actuate the SRV Solenoid Control State to toggle.
3. Using a 12-volt test light connected to ground, check the (K238) SRV Control circuit in the SRV harness connector.
  NOTE:
  If the DTC is active, the actuation test may not be allowed by the PCM. If may be necessary to clear the DTCs before starting the actuation.
  
  NOTE:
  The test light should illuminate on and off with the actuation.
  
  Does the test light illuminate on and off with the actuation?
  
  Yes
  - Replace the Short Runner Valve Assembly in accordance with the Service Information. Refer to MANIFOLD, INTAKE, REMOVAL, 5.7L .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 5
CHECK THE (K238) SRV CONTROL CIRCUIT FOR A SHORT TO GROUND

1. Turn the ignition off.
2. Disconnect the Powertrain Control Module (PCM) C2 harness connector.
3. Measure the resistance between ground and the (K238) SRV Control circuit in the SRV harness connector.
  Is the resistance less than 100 Ohms?
  
  Yes
  - Repair the (K238) Short Runner Valve Control circuit for a short to ground.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 6
CHECK THE (K238) SRV CONTROL CIRCUIT FOR AN OPEN OR HIGH RESISTANCE
1. Measure the resistance of the (K238) SRV Control 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 (K238) Short Runner Valve Control circuit for an open circuit or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK THE (K238) SRV SIGNAL CIRCUIT SHORTED TO VOLTAGE

1. Turn the ignition on
2. Measure the voltage between ground and the (K238) SRV Signal circuit in the Short Runner Valve Assembly harness connector.
  Is there any voltage present?
  
  Yes
  - Repair the (K238) Short Runner Valve Signal circuit for a short to voltage.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 8
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. Perform any Service Bulletins that may apply.
  Were any problems found?
  
  Yes
