Lock vehicle using remote transmitter. After vehicle completes locking and transmitter button is still depressed, .3-1 volt should exist. After vehicle completes locking and transmitter button is released, .3-1 volt should exist. If voltage is as specified, RCL receiver remote signal is okay at this time. If voltage is not as specified, check the following and repair as necessary:
