VTSS Test 12B - Right VTSS Disarm Malfunction

NOTE: Perform VTSS TEST 12A  before proceeding with this test. For connector terminal identification, refer to CONNECTOR IDENTIFICATION  . For wiring diagrams, refer to WIRING DIAGRAMS  . Perform, after each repair, TEST VER-1A - VERIFICATION PROCEDURE  .
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Remove key from ignition switch. Open passenger's door. Place key in passenger's door key lock cylinder. Rotate key to UNLOCK position and hold. Using scan tool, read RF DR DISARM voltage. If voltage is more than 9 volts, go to next step. If voltage is 9 volts or less, go tostep 3).
  2. Rotate key to LOCK position and hold. Using scan tool, read RF DR DISARM voltage. If voltage is more than 6.8 volts, replace BCM. If voltage is 6.8 volts or less, replace passenger's door key lock cylinder switch.
  3. Access passenger's door key lock cylinder harness. Disconnect lock cylinder connector. Using external voltmeter, measure voltage between ground and terminal No. 1 (Pink wire) on key cylinder switch connector. If voltage is 10 volts or less, repair open Pink wire. If voltage is more than 10 volts, go to next step.
  4. Using external ohmmeter, measure resistance between ground and terminal No. 2 (Dark Green/Orange wire) on key cylinder switch connector. If resistance is less than 5 ohms, repair Dark Green/Orange wire for short to ground. If resistance is 5 ohms or greater, go to next step.
  5. Connect jumper wire between key cylinder lock switch connector terminals. Using scan tool, read RF DR DISARM voltage. If voltage displayed is more than 9.5 volts, replace passenger's door key lock cylinder switch. If voltage is 9.5 volts or less, go to next step.
  6. Access BCM 20-pin connector located at junction block. See Figure in CHIME TEST 3A. Do not disconnect connector. Using external voltmeter, measure voltage between ground and terminal No. 20 (Dark Green/Orange wire) on 20-pin connector. If voltage is more than 10 volts, replace BCM. If voltage is 10 volts or less, repair open Light Green/Orange wire.
