Test E: Coast Switch Inoperative

  1. Check COAST Switch Operation  - Disconnect speed control servo/actuator connector C136 (located near master cylinder). While pressing COAST switch and rotating steering wheel, check resistance between speed control servo/actuator connector C136 terminals No. 5 and 6. See Figure . If resistance is 114-126 ohms, go to next step. If resistance is not 114-126 ohms, replace speed control switch assembly and retest system operation.
  2. Check Switch Return Circuit  - Using an ohmmeter, check resistance between speed control servo/actuator connector C136 terminals No. 6 and 10. If resistance is more than 10 k/ohms, replace speed control servo/actuator and retest system operation. If resistance is 10 k/ohms or less, repair shorted Dark Green/Orange wire. Retest system operation.
