Inhibitor Switch System Test (Maxima VG30E)

  1. Turn ignition off. Disconnect and inspect inhibitor switch 4-pin (contains Green/Black and Brown wires) harness connectors for pushed-out, bent, damaged or corroded terminals. Repair connector as necessary. Connector is located at right top of bellhousing. Turn ignition on. Measure voltage between Green/Black wire of inhibitor switch 4-pin connector and ground. Battery voltage should be present.
  2. If battery voltage is present, go to next step. If battery voltage is not present, turn ignition off. Check continuity between Green/Black wire of inhibitor switch harness connector and device side of 10-amp ENG CONT fuse. Continuity should exist. If continuity does not exist, check harness and connectors for open. Repair as necessary.
  3. Turn ignition off. Disconnect and inspect ECM harness connector for pushed-out, bent, damaged or corroded terminals. Repair connector as necessary. Check continuity between ECM harness connector terminal No. 44 (Brown wire) and Brown wire of inhibitor switch 4-pin connector. Continuity should exist. If continuity does not exist, check harness and connectors for open. Repair as necessary. If continuity exists, check inhibitor switch. See INHIBITOR SWITCH TEST (MAXIMA VG30E).
