Cruise Control Module
- Locate cruise control module behind right kick panel. Leave cruise control module harness connector attached unless other wise specified. Using DVOM, backprobe at specified terminals of cruise control module harness connector while performing appropriate test condition. See CRUISE CONTROL MODULE PIN VOLTAGE CHART table. See Fig 1
. Go to next step.
- If voltage measurements or continuity measurements are not as specified, check related components and wiring. See WIRINGS DIAGRAMS and appropriate component tests. If related components and wiring are okay, but system is still not functioning properly, replace cruise control module.
