Test T: Speed Control Indicator Is Never On

NOTE: After making any repairs, clear DTCs and perform self-test.
  1. Test drive vehicle and operate speed control system. If speed control operates correctly, go to next step. If speed control does not operate correctly, diagnose and repair as necessary. See CRUISE CONTROL SYSTEMS article.
  2. Turn ignition switch to LOCK position. Disconnect speed control servo 10-pin harness connector C157. Speed control servo is located in left rear corner of engine compartment. Connect a fused jumper wire (5-amp) between C157 terminal No. 1 (Orange/Light Blue wire) and ground. If speed control indicator illuminates, replace speed control servo and test system operation. If speed control indicator does not illuminate, repair open in Orange/Light Blue wire.
