Driver's Door Unlock Sensor Check
- Measure voltage by backprobing between terminal No. 36 (Light Green/Red wire) on SECU 24-pin harness connector and ground. See Figure
. Voltage should be zero volts with door unlocked and about 5 volts with door locked. If voltages are not as specified, go to next step. If voltages are as specified, door unlock sensor is okay.
- Perform door unlock sensor test. See SENSORS
under COMPONENT TESTS. If sensor is okay, inspect unlock sensor ground circuit (Black wire) and/or Light Green/Red wire for open or short between SECU and driver's door unlock sensor.
