Test 2: Door Unlock Detection Switch Circuit

With ignition switch in OFF position, remove luggage compartment left side panel. Remove wireless door lock ECU. Place all door lock knobs in lock position (door unlock detection switch off). For left front door, measure voltage between ground and ECU connector terminal No. 11 (Light Green/Black wire). For right front door, measure voltage between ground and ECU connector terminal No. 12 (Yellow wire). For rear doors, measure voltage between ground and ECU connector terminal No. 13 (Blue/Orange wire). See Figure. Battery voltage should exist at each individual voltage reading. If battery voltage does not exist, repair appropriate circuit. If battery voltage exists, proceed to next test given in TROUBLE SHOOTING SYMPTOMS  table.
