Diagnostic Test

WARNING: This page is about a different variant/trim than selected.

DTC IS ACTIVE
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, select View DTCs.
  Is the status Active for this DTC?
  
  Yes
  - Go To 2.
  No
  - Refer to STANDARD PROCEDURE and perform the INTERMITTENT CONDITION diagnostic procedure.
(F342) 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 (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 open or high resistance in the (F342) ASD Relay Output circuit.
  - Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
HIGH RESISTANCE IN THE (Z903) SRV GROUND CIRCUIT OPEN CIRCUIT
1. Turn the ignition off.
2. Measure the resistance between ground and the (Z903) SRV Ground circuit in the Short Runner Valve Assembly harness connector.
  Is the resistance less than 5.0 Ohms?
  
  Yes
  - Go To 4.
  No
  - Repair the open or high resistance in the (Z903) SRV ground circuit.
  - Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
HIGH RESISTANCE IN THE (K238) SRV CONTROL CIRCUIT
1. Disconnect the PCM C2 harness connector.
2. Measure the resistance of the (K238) SRV control circuit between the Short Runner Valve Assembly harness connector and the PCM C2 harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 5.
  No
  - Repair the open or high resistance in the (K238) SRV Control circuit.
  - Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
HIGH RESISTANCE IN THE (K237) SRV SIGNAL CIRCUIT
1. Measure the resistance of the (K237) SRV signal circuit between the Short Runner Valve Assembly harness connector and the PCM C2 harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 6.
  No
  - Repair the open or high resistance in the (K237) SRV signal circuit for.
  - Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
SHORT RUNNER VALVE ASSEMBLY
1. Connect the PCM C2 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 (K238) 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. It 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 STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
  No
  - Go To 7.
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 Technical Service Bulletins that may apply.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
  No
  - Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information.
  - Refer to STANDARD PROCEDURE and perform the POWERTRAIN VERIFICATION TEST.
