Control Unit Test
CAUTION:
On models equipped with Supplemental Restraint System (SRS), SRS wire harness is routed near cruise control related parts. All SRS wire harness terminals are colored Yellow. DO NOT use electrical test equipment on these circuits.
Turn ignition off. Disconnect control unit connector, located under left side of dash. Using a DVOM, check wire(s) specified under test condition. See Fig 1 or Fig 2 for control unit testing. If all test results are okay, replace control unit.
