Pinpoint Test C: The Adjustable Pedal Does Not Operate

WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
  1. C1 CHECK MOTOR SOUND 
    • Allow 2 minutes for the thermal overload to reset.
    • Operate the adjustable pedal control switch.
    • Can the adjustable pedal motor be heard to operate? 
      1. Yes  : GO to C2.
      2. No  : GO to  C6.
  2. C2 CHECK MOTOR INSTALLATION 
    • Check adjustable pedal motor for correct installation.
    • Is the motor installation OK? 
      1. Yes  : GO to C3.
      2. No  : CORRECT the motor installation. TEST the system for normal operation.
  3. C3 CHECK ADJUSTABLE ACCELERATOR PEDAL SYSTEM 
    • Disconnect the brake pedal-to-accelerator pedal cable.
    • Operate the adjustable pedal control switch.
    • Does the adjustable brake pedal operate now? 
      1. Yes  : REPAIR the adjustable accelerator pedal system. REFER to FUEL SYSTEM . TEST the system for normal operation.
      2. No  : GO to C4.
  4. C4 INSPECT FOR FOREIGN MATERIAL 
    • Inspect the adjustable brake pedal assembly for foreign material causing a binding condition.
    • Was any foreign material found? 
      1. Yes  : REMOVE the foreign material. RETEST for normal operation.
      2. No  : GO to C5.
  5. C5 CHECK CABLE 
    • Dismount the adjustable pedal motor.
    • Inspect the ends of the brake pedal motor cable for wear or damage.
    • Are the cable ends OK? 
      1. Yes  : GO to C6.
      2. No  : INSTALL a new brake pedal motor cable. TEST the system for normal operation.
  6. C6 CHECK POWER TO SWITCH 
    • Disconnect: Adjustable Pedal Switch C2089.
    • Measure the voltage at C2089-3, circuit 32-AL19 (WH/GN) and C2089-7, circuit 34-AL19 (BU/BK).
    • Is the voltage greater than 10 volts? 
      1. Yes  : GO to C7.
      2. No  : REPAIR circuit in question. TEST the system for normal operation.
  7. C7 CHECK GROUND TO SWITCH 
    • Measure resistance to ground at C2089-4, circuit 31-AL19A(BK/GN).
    • Is the resistance less than 5 ohms? 
      1. Yes  : GO to C8.
      2. No  : REPAIR the circuit. TEST the system for normal operation.
  8. C8 CHECK CIRCUITS FOR SHORT TO BATTERY 
    • Disconnect: FEM C201b.
    • Measure voltage at C2089-3 and C2089-7.
    • Is the voltage greater than 0 volts at either pin? 
      1. Yes  : REPAIR the short to battery. TEST the system for normal operation.
      2. No  : GO to C9.
  9. C9 CHECK CIRCUITS FOR SHORT TO GROUND 
    • Measure resistance to ground at C2089-3 and C2089-7.
    • Are the resistance greater than 10,000 ohms? 
      1. Yes  : GO to C10.
      2. No  : REPAIR the circuit. TEST the system for normal operation.
  10. C10 CHECK SWITCH-TO-MOTOR CIRCUITS CONTINUITY 
    • Connect: Adjustable Pedal Switch C2089.
    • Disconnect: Adjustable Pedal Motor C268.
    • Measure resistance to ground at both pins of the adjustable pedal motor connector, circuits 34-AL19 (BU/RD) and 35-AL18 (VT/BU).
    • Is the resistance less than 5 ohms at both pins? 
      1. Yes  : INSTALL a new adjustable pedal motor. TEST the system for normal operation.
      2. No  : REPAIR the circuit. TEST the system for normal operation.
