VTSS Fails To Arm/Disarm From Drivers Cylinder Lock Switch

NOTE: After making any repairs, perform VTSS VERIFICATION TEST  under VERIFICATION TESTS.
  1. Open driver's door and operate door locks from door lock switch. If door locks operate properly, go to next step. If door locks do not operate properly, perform ALL LOCKS INOPERATIVE FROM A LOCK SWITCH  test under POWER DOOR LOCKS/REMOTE KEYLESS ENTRY.
  2. Disconnect driver's cylinder lock switch 2-pin connector. Using an ohmmeter, check resistance between driver's cylinder lock switch connector terminal No. 2, ground circuit and ground. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open wire.
  3. Using a voltmeter, check voltage between drivers cylinder lock switch connector terminal No. 1, driver's door switch multiplex circuit and ground. If voltage is about 5 volts, replace driver's cylinder lock switch. If voltage is 4.5 volts or less, repair open wire.
