Check Door Switch Input Signal

Using DVOM, measure voltage (backprobe) between ground and specified terminals at Smart Entrance Control Unit (SECU) harness connector. See DOOR SWITCH CIRCUIT TEST table. If voltage is as specified, door switch is okay. If voltage is not as specified, go to next step.
