Test K: Set/ACCEL Switch Inoperative

  1. Turn ignition switch to ON position. Using New Generation Star (NGS) tester or Worldwide Diagnostic System (WDS) tester, monitor speed control servo/actuator PID SET_ACL. Depress and release speed control switch SET/ACCEL button while slightly turning steering wheel from side to side. If NGS/WDS tester does not indicate ACTIVE with SET/ACCEL button depressed and NOTACT with SET/ACCEL button released, go to next step. If NGS/WDS tester indicates ACTIVE with SET/ACCEL button depressed and NOTACT with SET/ACCEL button released, system is okay.
  2. Turn ignition switch to OFF position. Disconnect speed control servo/actuator 10-pin harness connector C116. Measure resistance between speed control servo/actuator harness connector C116 terminals No. 5 (Light Blue/Black wire) and No. 6 (Dark Green/Orange wire) while pressing speed control switch SET/ACCEL button and slightly turning steering wheel from side to side. See Figure . Resistance should be 612-748 ohms with SET/ACCEL button pressed and more than 10 k/ohms with SET/ACCEL button released. If resistance is as specified, replace speed control servo/actuator. See SPEED CONTROL SERVO/ACTUATOR  under REMOVAL & INSTALLATION. If resistance is not as specified, replace speed control switch. See SPEED CONTROL SWITCH  under REMOVAL & INSTALLATION.
