Test 19F - Diagnosing Door Lock & Unlock Circuit
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS
article in the ENGINE PERFORMANCE Section. Perform TEST VER - 1A after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition off. Remove appropriate door panel to gain access to inoperative door lock switch. Using DRB-II in voltmeter mode, measure voltage of fused battery feed circuit at door lock switch (Pink wire).
- If voltage is less than 10 volts, repair open Pink wire. If voltage is more than 10 volts, measure voltage of switched battery feed circuit at door lock switch (Pink/Violet wire).
- Monitor DRB-II voltage while depressing power door lock switch to LOCK position. If voltage is more than 10 volts when switch is depressed, replace defective door lock switch. If voltage is less than 10 volts when switch is depressed, repair open Pink/Violet wire and Orange/Violet wire.
