  1. Condition to set trouble code is not present at this time. SPEED CONTROL SWITCH ALWAYS HIGH DTC sets if an open condition is detected in speed control ON/OFF switch circuit. Possible causes are: multiplexing switch(es) (speed control switches) shorted to power, multiplexing switch(es) (speed control switches) open, ON/OFF switch open or Powertrain Control Module (PCM) failure.
  2. Observe scan tool voltmeter. Wiggle wiring harness between speed control ON/OFF switch and Powertrain Control Module (PCM).
