  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. Go to next step.
  2. Observe scan tool speed control switch voltage. Wiggle wiring harness between speed control ON/OFF switch and Powertrain Control Module (PCM). If voltage was more than 4.9 volts at any time, repair wiring harness as necessary where wiggling caused problem to appear. Perform TEST SC-VER  . If voltage was not more than 4.9 volts at any time, problem is not present at this time. Test is complete. Perform TEST SC-VER  .
