Diagnostic Test

CHECK FOR AN ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, read DTCs and record the related Freeze Frame data.
  Is the DTC active?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
CHECK THE (F343) ASD RELAY 2 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 (F343) ASD Relay 2 Output circuit.
  NOTE:
  The test light must be brightly lit. If the test light does not light or is Dim repair the circuit for a open or high resistance circuit.
  
  Does the test light illuminate brightly?
  
  Yes
  - Go To 3
  No
  - Repair the (F343) ASD Relay 2 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 between ground and 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 4
CHECK THE (K333) REVERSE LOCKOUT SOLENOID CONTROL CIRCUIT FOR AN OPEN
1. Turn the ignition off.
2. Disconnect the PCM C4 harness connector.
3. Measure the resistance of the (K333) Reverse Lockout Solenoid Control circuit between the PCM connector and the Reverse Lockout Solenoid connector.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Go To 5
  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 6
REVERSE LOCKOUT SOLENOID
1. Measure the resistance across both 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 7
  No
  - Verify that there is good pin to terminal contact in the 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 .
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Solenoid 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. Verify that there is good pin to terminal contact in the Solenoid and Powertrain Control Module connectors.
5. Perform any Service Bulletins that may apply.
  Repair
  - Replace and program the Powertrain Control Module in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL (PCM), REMOVAL , MODULE, POWERTRAIN CONTROL (PCM), INSTALLATION and MODULE PROGRAMMING .
  - Perform the PCM VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
