Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

DTC IS ACTIVE
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 INTERMITTENT CONDITION .
(F344) ASD RELAY OUTPUT CIRCUIT 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 (F344) ASD Relay Output circuit in the Short Runner Valve Assembly 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 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 (F344) ASD Relay Output 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 off.
2. Disconnect the Short Runner Valve Assembly connector.
3. Turn the ignition on.
4. With the scan tool, read the SRV PWM Feedback.
  NOTE:
  The SRV PWM Feedback should be greater than 97% with the connector disconnected.
  
  Is the SRV PWM Feedback greater than 97%?
  
  Yes
  - Replace the Short Runner Valve Assembly in accordance with the Service Information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 4.
(K237) SRV SIGNAL CIRCUIT SHORTED TO GROUND

1. Turn the ignition off.
2. Disconnect the Powertrain Control Module (PCM) C1 harness connector.
3. Measure the resistance between ground and the (K237) SRV Signal circuit in the Short Runner Valve Assembly harness connector.
  Is the resistance less than 100 Ohms?
  
  Yes
  - Repair the (K237) SRV signal circuit for a short to ground.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 5.
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 POWERTRAIN VERIFICATION TEST .
  No
  - Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
