Test 8: Park/Neutral Position Switch

NOTE: Park/Neutral position switch includes a diode. If circuit shows no continuity, reverse positive and negative test leads and retest circuit.
  1. Ensure starting system is operating normally. Disconnect CC ECU connector (12-pin connector "A", models with motor actuator). Set shift lever to "P" or "N" position. Ensure continuity exists between ground and CC ECU connector terminal No. A4 (with motor actuator, Black wire) or No. 13 (with vacuum actuator, Black wire). If continuity is not present, repair open in harness between CC ECU terminal No. 2 or No. A4 or No. 13 and park/neutral position switch connector terminal No. 2 (Black/White wire).
  2. Set shift lever to "L", 2, 3, and "R" positions. Ensure no continuity exists between ground and CC ECU connector terminal No. A4 (with motor actuator) or No. 13 (with vacuum actuator). If continuity is not present, replace CC ECU and retest system. If continuity is present, repair short in harness between terminal No. 2 or No. A4 or No. 13 and park/neutral position switch connector terminal No. 2 (Black/White wire).
