Test 11, Park/Neutral Position 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 park/neutral position switch test. See CANCEL SWITCHES under CRUISE CONTROL CIRCUIT FUNCTION TEST  under TROUBLE SHOOTING. If park/neutral position switch input signal is as specified, go to test for next trouble code displayed or appropriate TROUBLE SHOOTING BY SYMPTOM . 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 (Black/White wire) and put negative lead to ground. Ensure less than one volt exists with shift lever in Park or Neutral, and battery voltage exists with shift lever in other positions. If voltage is as specified, go to test for next trouble code displayed or appropriate TROUBLE SHOOTING BY SYMPTOM . If voltage is not as specified, go to next step.
  4. Check harness and connectors between CC ECU and ST or GAUGE fuse. Repair or replace as necessary. If harness and connectors are okay, replace CC ECU and retest system.
