7. With the scan tool, read DTCs.
  Did the DTC return?
  
  Yes
  - Go To 3
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
CHECK THE (F342) ASD CONTROL OUTPUT CIRCUIT FOR AN OPEN OR SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the Reverse Lockout Solenoid harness connector.
3. Turn the ignition on.
4. Using a 12-volt test light connected to ground, probe the (F342) ASD Control Output circuit at Reverse Lockout Solenoid harness connector.
  NOTE:
  The 12 volt test light should be illuminated and bright as compared to the connection of direct Battery.
  
  Does the test light illuminate brightly?
  
  Yes
  - Go To 4
  No
  - Repair the (F342) ASD Control Output circuit for an open or short to ground.
  - Perform the PCM VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK THE (K333) REVERSE LOCKOUT SOLENOID CONTROL CIRCUIT FOR A SHORT TO VOLTAGE
1. Measure the voltage on the (K333) Reverse Lockout Solenoid Control circuit at the Reverse Lockout Solenoid connector.
  Is there any voltage present?
  
  Yes
  - Repair the (K333) Reverse Lockout Solenoid Control circuit for a short to voltage.
  - Perform the PCM VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 5
CHECK THE (K333) REVERSE LOCKOUT SOLENOID CONTROL CIRCUIT FOR AN OPEN
1. Turn the ignition off.
2. Disconnect the PCM C2 harness connector.
  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 the GPEC Diagnostic Adaptor to perform the diagnosis.
3. Connect the(special tool #10436, Adapter, GPEC Diagnostic)to the appropriate PCM connector.
  NOTE:
  The GPEC Diagnostic Adaptor can add up to 1.5 Ohms of resistance to the circuit.
4. Measure the resistance of the (K333) Reverse Lockout Solenoid Control circuit between the Reverse Lockout Solenoid harness connector and the GPEC Diagnostic Adaptor.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Go To 6
  No
  - Repair the (K333) Reverse Lockout Solenoid Control circuit for an open or high resistance.
  - Perform the PCM VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK THE (K333) REVERSE LOCKOUT SOLENOID CONTROL CIRCUIT FOR A SHORT TO GROUND
1. Check for continuity between ground and the (K333) Reverse Lockout Solenoid Control circuit at the Solenoid harness connector.
  Is there continuity between ground and the (K333) Reverse Lockout Solenoid Control circuit?
  
  Yes
  - Repair the (K333) Reverse Lockout Solenoid Control circuit for a short to ground.
  - Perform the PCM VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 7
CHECK THE RESISTANCE OF THE REVERSE LOCKOUT SOLENOID
1. Measure the resistance across terminals of the Reverse Lockout Solenoid.
  NOTE:
  The resistance should be approximately 13.5 Ohms at 25°C. (77°F).
  
  Is the resistance between 12.0 Ohms and 15.0 Ohms?
  
  Yes
  - Go To 8
  No
  - Verify that there is good pin to terminal contact in the Reverse Lockout Solenoid and Powertrain Control Module connectors. If no problems are found, replace the Reverse Lockout Solenoid.
  - Perform the PCM VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK RELATED PCM AND COMPONENT CONNECTIONS
1. Perform any Service Bulletins that apply.
2. Disconnect all PCM harness connectors.
3. Disconnect all related in-line harness connections (if equipped).
4. Disconnect the related component harness connectors.
5. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
  - Proper connector installation.
  - Damaged connector locks.
  - Corrosion.
  - Other signs of water intrusion.
  - Weather seal damage (if equipped).
  - Bent terminals.
  - Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
  - Terminals that have been pushed back into the connector cavity.
  - Check for spread terminals and verify proper terminal tension.
  Repair any conditions that are found.
6. Reconnect all PCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
7. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
9. With the scan tool, erase DTCs.
10. Test drive or operate the vehicle in accordance with the when monitored and set conditions.
11. With the scan tool, read DTCs.
