Diagnostic Test

  1. 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 DTC Active at this time?

      Yes 

      • Go to step  2

      No 

  2. (F343) 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 (F343) 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 step  3

      No 

  3. (K236) SRV CONTROL CIRCUIT SHORTED TO GROUND

    1. Turn the ignition off.
    2. Disconnect the C1 Powertrain Control Module (PCM) harness connector.
    3. Measure the resistance between ground and the (K236) SRV Control circuit in the Short Runner Valve Assembly harness connector.

      Is the resistance above 100 ohms?

      Yes 

      • Go to step  4

      No 

  4. (K236) SRV CONTROL CIRCUIT OPEN OR HIGH RESISTANCE

    CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals, resulting in poor terminal to pin connection. Install PCM Pinout Box 8815 to perform diagnosis.
    1. Measure the resistance of the (K236) SRV Control circuit between the Short Runner Valve Assembly harness connector and the appropriate terminal of special tool #8815.

      Is the resistance below 5.0 ohms?

      Yes 

      • Go to step  5

      No 

  5. SHORT RUNNER VALVE ASSEMBLY

    1. Connect the C1 Powertrain Control Module (PCM) harness connector.
    2. Turn the ignition on.
    3. With the scan tool, actuate the SRV Solenoid Control State to toggle.
    4. Using a 12 volt test light connected to 12 volts, check the (K236) SRV Control 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 illuminate on and off with the actuation.

      Does the test light illuminate on and off with the actuation?

      Yes 

      No 

      • Go to step  6
  6. 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. Verify that there is good pin to terminal contact in the Short Runner Valve Assembly and Powertrain Control Module connectors.
    4. Look for broken, bent, pushed out or corroded terminals.
    5. Refer to any Technical Service Bulletins that may apply.

      Were any problems found?

      Yes 

      No
