    2. Disconnect the Right Seat Stow Motor harness connector.
    3. Disconnect the FSM C2 harness connector.
    4. Turn the ignition on.
    5. Measure the voltage of the (P300) Right Folding Seat Stow Motor Rearward Driver circuit at the FSM C2 harness connector.

      Is there any voltage present?

      Yes 

      No 

      • Go To  5
  5. CHECK THE (P299) RIGHT FOLDING SEAT STOW MOTOR FORWARD DRIVER CIRCUIT FOR A SHORT TO VOLTAGE 
    1. Measure the voltage of the (P299) Right Folding Seat Stow Motor Forward Driver circuit at the FSM C2 harness connector.

      Is there any voltage present?

      Yes 

      No 

      • Go To  6
  6. CHECK THE (P300) RIGHT FOLDING SEAT STOW MOTOR REARWARD DRIVER CIRCUIT FOR A SHORT TO GROUND 
    1. Turn the ignition off.
    2. Check for continuity between ground and the (P300) Right Folding Seat Stow Motor Rearward Driver circuit at the FSM C2 harness connector.

      Is there continuity between ground and the (P300) Right Folding Seat Stow Motor Rearward Driver circuit?

      Yes 

      No 

      • Go To  7
  7. CHECK THE (P299) RIGHT FOLDING SEAT STOW MOTOR FORWARD DRIVER CIRCUIT FOR A SHORT TO GROUND

      Is there continuity between ground and the (P299) Right Folding Seat Stow Motor Forward Driver circuit?

      Yes 

      No 

      • Go To  8
  8. CHECK THE (P300) RIGHT FOLDING SEAT STOW MOTOR REARWARD DRIVER CIRCUIT FOR AN OPEN 
    1. Measure the resistance of the (P300) Right Folding Seat Stow Motor Rearward Driver circuit between the FSM C2 harness connector and the Right Seat Stow Motor harness connector.

      Is the resistance below 3.0 ohms?

      Yes 

      • Go To  9

      No 

  9. CHECK THE (P299) RIGHT FOLDING SEAT STOW MOTOR FORWARD DRIVER CIRCUIT FOR AN OPEN 
    1. Measure the resistance of the (P299) Right Folding Seat Stow Motor Forward Driver circuit between the FSM C2 harness connector and the Right Seat Stow Motor harness connector.

      Is the resistance below 3.0 ohms?

      Yes 

      • Go To  10

      No 

  10. REPLACE THE RIGHT SEAT STOW MOTOR - PERFORM THE POWER FOLDING SEAT SYSTEM VERIFICATION TEST AND CHECK FOR DTC TO RETURN

    2. Perform the POWER FOLDING SEAT SYSTEM VERIFICATION TEST. Refer to POWER FOLDING SEAT SYSTEM VERIFICATION TEST  .

      Did the DTC return?

      Yes 

      • Go To  11

      No 

      • Replacing the Stow Motor corrected the condition.
  11. CHECK RELATED HARNESS CONNECTIONS 
    1. Turn the ignition off.
    2. Disconnect all FSM 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.
      • Perform a terminal drag test on each connector terminal to verify proper terminal tension.

      Repair any conditions that are found.
