Action Taken:
Disengage cruise control.
When cruise control is on, system voltage is available at one normally open contact of the SET/COAST and RESUME/ACCEL. switches. If the cruise control switch is in the ON position, this voltage is available to the switches when ignition switch is turned to the ON position. If SET/COAST or RESUME/ACCEL. switches were stuck on or shorted to power, cruise control operation would begin. To prevent this, Code EO67 will set and cruise control operation is disabled if signal voltage from SET/COAST (circuit No. 84) or RESUME/ACCEL. (circuit No. 87) is HI continually for 10 minutes. Cruise control will be disengaged until ECM sees a LO on both of these signals.
