Test 12: Clutch Switch

  1. Ensure starting system is operating normally. Check for starting system problems and repair as necessary. If starting system is okay, go to next step.
  2. Perform clutch switch position test. See CRUISE CONTROL CIRCUIT FUNCTION TEST  under TROUBLE SHOOTING. If clutch switch input signal is as specified, go to test for next trouble code displayed. If input signal is not as specified, go to next step.
  3. Remove CC ECU with connector connected. Turn ignition on, using voltmeter positive lead, backprobe CC ECU connector terminal No. 2/N & C (Black wire) with negative lead to ground. Ensure less than one volt exists with clutch pedal depressed (switch on), and battery voltage exists with clutch pedal released (switch off). If voltage is as specified, go to test for next trouble code displayed. If voltage is not as specified, go to next step.
  4. Ensure continuity exists between CC ECU connector terminal No. 2 and ground with clutch pedal depressed (switch on). If continuity is not present, repair open in circuit between CC ECU connector terminal No. 2 and clutch switch. If continuity is present, replace CC ECU and retest system.
