Pinpoint Test C: Cannot Change Suspension Modes Using The Ride Control Switch

WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
  1. C1 CHECK FOR VDM DTCS 
    • Enter the following diagnostic mode on the scan tool: Self Test - VDM.
    • Are any DTCs present in the VDM? 
    • Yes  : DIAGNOSE all VDM DTCs before diagnosing the ride control switch. GO to the VDM DTC Chart .
    • No  : GO to C2.
  2. C2 CHECK THE RIDE CONTROL SWITCH CIRCUITS FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Disconnect: Ride Control Switch C2473.
    • Disconnect: PCM C175B.
    • Ignition ON.
    • Measure the voltage  between:
      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C2473-4 RMC27 (WH/BN) - Ground
      C2473-5 CMC29 (GN/VT) - Ground

    • Is any voltage present? 
    • Yes  : REPAIR the circuit.
    • No  : GO to C3.
  3. C3 CHECK THE RIDE CONTROL SWITCH CIRCUITS FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Measure the resistance  between:
      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C2473-4 RMC27 (WH/BN) - Ground
      C2473-5 CMC29 (GN/VT) - Ground

    • Are the resistances greater than 10, 000 ohms? 
    • Yes  : GO to C4.
    • No  : REPAIR the circuit.
  4. C4 CHECK THE RIDE CONTROL SWITCH CIRCUITS FOR AN OPEN 
    NOTE: The circuits pass through an in-line connector, C211, circuit RMC27 changes to RE405 at C211.
    • Measure the resistance  between:
      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C2473-4 RMC27 (WH/BN) C175B-56 RE405 (GN/WH)
      C2473-5 CMC29 (GN/VT) C175B-17 CMC29 (GN/VT)

    • Are the resistances less than 3 ohms? 
    • Yes  : GO to C5.
    • No  : REPAIR the circuit.
  5. C5 CHECK THE RIDE CONTROL SWITCH CIRCUITS FOR A SHORT TOGETHER 
    • Measure the resistance  between:
      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C2473-4 RMC27 (WH/BN) - Ground
      C2473-5 CMC29 (GN/VT) - Ground

    • Are the resistances greater than 10, 000 ohms? 
    • Yes  : GO to C6.
    • No  : REPAIR the circuits.
  6. C6 CHECK THE PCM RIDE CONTROL SWITCH OUTPUT 
    • Connect: PCM C175B.
    • Ignition ON.
    • Measure the voltage  between:
      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C2473-5 CMC29 (GN/VT) - Ground
