Cruise Control Module

  1. Locate cruise control module behind right kick panel. Leave cruise control module harness connector attached.
  2. Using DVOM, backprobe specified terminals of cruise control module harness connector while performing appropriate test condition. See CRUISE CONTROL MODULE PIN VOLTAGE  table. See Fig 1 .
  3. If voltage measurements or continuity measurements are not as specified, check related components and wiring. See WIRING DIAGRAMS  . If related components and wiring are okay, but system is still not functioning properly, replace cruise control module.
